He handed me the two papers, of which one gave the actual words of the cryptogram, and the other a suggested reconstruction, with omitted words supplied. The first read:

"Woe city lies robbery prey noise whip rattling wheel horse chariot day darkness gloominess cloud darkness morning mountain people strong fire them flame."

Turning to the second paper, I read out the suggested rendering:

"'Woe to the bloody city! It is full of lies and robbery; the prey departeth not. The noise of a whip, and the noise of the rattling of the wheels, and of the prancing horses, and of the jumping chariots.

"'A day of darkness and of gloominess, a day of clouds, and of thick darkness, as the morning spread upon the mountains, a great people and a strong.

"'A fire devoureth before them, and behind them a flame burneth.'"

Here the first sheet ended, and, as I laid it down, Thorndyke looked at me inquiringly.

"There is a good deal of reconstruction in proportion to the original matter," I objected. "The Professor has 'supplied' more than three-quarters of the final rendering."

"Exactly," burst in the superintendent; "it's all Professor and no cryptogram."

"Still, I think the reading is correct," said Thorndyke. "As far as it goes, that is."

"Good Lord!" exclaimed the dismayed detective. "Do you mean to tell me, sir, that that balderdash is the real meaning of the thing?"

"I don't say that," replied Thorndyke. "I say it is correct as far as it goes; but I doubt its being the solution of the cryptogram."

"Have you been studying that photograph that I gave you?" demanded Miller, with sudden eagerness.

"I have looked at it," said Thorndyke evasively, "but I should like to examine the original if you have it with you."

"I have," said the detective. "Professor Poppelbaum sent it back with the solution. You can have a look at it, though I can't leave it with you without special authority."

He drew the document from his pocket-book and handed it to Thorndyke, who took it over to the window and scrutinized it closely. From the window he drifted into the adjacent office, closing the door after him; and presently the sound of a faint explosion told me that he had lighted the gas-fire.

"Of course," said Miller, taking up the translation again, "this gibberish is the sort of stuff you might expect from a parcel of crack-brained anarchists; but it doesn't seem to mean anything."

"Not to us," I agreed; "but the phrases may have some pre-arranged significance. And then there are the letters between the words. It is possible that they may really form a cipher."

"I suggested that to the Professor," said Miller, "but he wouldn't hear of it. He is sure they are only dummies."

"I think he is probably mistaken, and so, I fancy, does my colleague. But we shall hear what he has to say presently."

"Oh, I know what he will say," growled Miller. "He will put the thing under the microscope, and tell us who made the paper, and what the ink is composed of, and then we shall be just where we were." The superintendent was evidently deeply depressed.

We sat for some time pondering in silence on the vague sentences of the Professor's translation, until, at length, Thorndyke reappeared, holding the document in his hand. He laid it quietly on the table by the officer, and then inquired:

"Is this an official consultation?"

"Certainly," replied Miller. "I was authorized to consult you respecting the translation, but nothing was said about the original. Still, if you want it for further study, I will get it for you."

"No, thank you," said Thorndyke. "I have finished with it. My theory turned out to be correct."

"Your theory!" exclaimed the superintendent, eagerly. "Do you mean to say—?"

"And, as you are consulting me officially, I may as well give you this."

He held out a sheet of paper, which the detective took from him and began to read.

"What is this?" he asked, looking up at Thorndyke with a puzzled frown. "Where did it come from?"

"It is the solution of the cryptogram," replied Thorndyke.

The detective re-read the contents of the paper, and, with the frown of perplexity deepening, once more gazed at my colleague.

"This is a joke, sir; you are fooling me," he said sulkily.

"Nothing of the kind," answered Thorndyke. "That is the genuine solution."

"But it's impossible!" exclaimed Miller. "Just look at it, Dr. Jervis."

I took the paper from his hand, and, as I glanced at it, I had no difficulty in understanding his surprise. It bore a short inscription in printed Roman capitals, thus:

"THE PICKERDILLEY STUF IS UP THE CHIMBLY 416 WARDOUR ST 2ND FLOUR BACK IT WAS HID BECOS OF OLD MOAKEYS JOOD MOAKEY IS A BLITER."

"Then that fellow wasn't an anarchist at all?" I exclaimed.

"No," said Miller. "He was one of Moakey's gang. We suspected Moakey of being mixed up with that job, but we couldn't fix it on him. By Jove!" he added, slapping his thigh, "if this is right, and I can lay my hands on the loot! Can you lend me a bag, doctor? I'm off to Wardour Street this very moment."

We furnished him with an empty suit-case, and, from the window, watched him making for Mitre Court at a smart double.

"I wonder if he will find the booty," said Thorndyke. "It just depends on whether the hiding-place was known to more than one of the gang. Well, it has been a quaint case, and instructive, too. I suspect our friend Barton and the evasive Schoenberg were the collaborators who produced that curiosity of literature."

"May I ask how you deciphered the thing?" I said. "It didn't appear to take long."

"It didn't. It was merely a matter of testing a hypothesis; and you ought not to have to ask that question," he added, with mock severity, "seeing that you had what turn out to have been all the necessary facts, two days ago. But I will prepare a document and demonstrate to you to-morrow morning."

* * * * *

"So Miller was successful in his quest," said Thorndyke, as we smoked our morning pipes after breakfast. "The 'entire swag,' as he calls it, was 'up the chimbly,' undisturbed."

He handed me a note which had been left, with the empty suit-case, by a messenger, shortly before, and I was about to read it when an agitated knock was heard at our door. The visitor, whom I admitted, was a rather haggard and dishevelled elderly gentleman, who, as he entered, peered inquisitively through his concave spectacles from one of us to the other.

"Allow me to introduce myself, gentlemen," said he. "I am Professor Poppelbaum."

Thorndyke bowed and offered a chair.

"I called yesterday afternoon," our visitor continued, "at Scotland Yard, where I heard of your remarkable decipherment and of the convincing proof of its correctness. Thereupon I borrowed the cryptogram, and have spent the entire night in studying it, but I cannot connect your solution with any of the characters. I wonder if you would do me the great favour of enlightening me as to your method of decipherment, and so save me further sleepless nights? You may rely on my discretion."

"Have you the document with you?" asked Thorndyke.

The Professor produced it from his pocket-book, and passed it to my colleague.

"You observe, Professor," said the latter, "that this is a laid paper, and has no water-mark?"

"Yes, I noticed that."

"And that the writing is in indelible Chinese ink?"

"Yes, yes," said the savant impatiently; "but it is the inscription that interests me, not the paper and ink."

"Precisely," said Thorndyke. "Now, it was the ink that interested me when I caught a glimpse of the document three days ago. 'Why,' I asked myself, 'should anyone use this troublesome medium'—for this appears to be stick ink—'when good writing ink is to be had?' What advantages has Chinese ink over writing ink? It has several advantages as a drawing ink, but for writing purposes it has only one: it is quite unaffected by wet. The obvious inference, then, was that this document was, for some reason, likely to be exposed to wet. But this inference instantly suggested another, which I was yesterday able to put to the test—thus."

He filled a tumbler with water, and, rolling up the document, dropped it in. Immediately there began to appear on it a new set of characters of a curious grey colour. In a few seconds Thorndyke lifted out the wet paper, and held it up to the light, and now there was plainly visible an inscription in transparent lettering, like a very distinct water-mark. It was in printed Roman capitals, written across the other writing, and read:

"THE PICKERDILLEY STUF IS UP THE CHIMBLY 416 WARDOUR ST 2ND FLOUR BACK IT WAS HID BECOS OF OLD MOAKEYS JOOD MOAKEY IS A BLITER."

The Professor regarded the inscription with profound disfavour.

"How do you suppose this was done?" he asked gloomily.

"I will show you," said Thorndyke. "I have prepared a piece of paper to demonstrate the process to Dr. Jervis. It is exceedingly simple."

He fetched from the office a small plate of glass, and a photographic dish in which a piece of thin notepaper was soaking in water.

"This paper," said Thorndyke, lifting it out and laying it on the glass, "has been soaking all night, and is now quite pulpy."

He spread a dry sheet of paper over the wet one, and on the former wrote heavily with a hard pencil, "Moakey is a bliter." On lifting the upper sheet, the writing was seen to be transferred in a deep grey to the wet paper, and when the latter was held up to the light the inscription stood out clear and transparent as if written with oil.

"When this dries," said Thorndyke, "the writing will completely disappear, but it will reappear whenever the paper is again wetted."

The Professor nodded.

"Very ingenious," said he—"a sort of artificial palimpsest, in fact. But I do not understand how that illiterate man could have written in the difficult Moabite script."

"He did not," said Thorndyke. "The 'cryptogram' was probably written by one of the leaders of the gang, who, no doubt, supplied copies to the other members to use instead of blank paper for secret communications. The object of the Moabite writing was evidently to divert attention from the paper itself, in case the communication fell into the wrong hands, and I must say it seems to have answered its purpose very well."

The Professor started, stung by the sudden recollection of his labours.

"Yes," he snorted; "but I am a scholar, sir, not a policeman. Every man to his trade."

He snatched up his hat, and with a curt "Good-morning," flung out of the room in dudgeon.

Thorndyke laughed softly.

"Poor Professor!" he murmured. "Our playful friend Barton has much to answer for."



VI

THE MANDARIN'S PEARL

Mr. Brodribb stretched out his toes on the kerb before the blazing fire with the air of a man who is by no means insensible to physical comfort.

"You are really an extraordinarily polite fellow, Thorndyke," said he.

He was an elderly man, rosy-gilled, portly, and convivial, to whom a mass of bushy, white hair, an expansive double chin, and a certain prim sumptuousness of dress imparted an air of old-world distinction. Indeed, as he dipped an amethystine nose into his wine-glass, and gazed thoughtfully at the glowing end of his cigar, he looked the very type of the well-to-do lawyer of an older generation.

"You are really an extraordinarily polite fellow, Thorndyke," said Mr. Brodribb.

"I know," replied Thorndyke. "But why this reference to an admitted fact?"

"The truth has just dawned on me," said the solicitor. "Here am I, dropping in on you, uninvited and unannounced, sitting in your own armchair before your fire, smoking your cigars, drinking your Burgundy—and deuced good Burgundy, too, let me add—and you have not dropped a single hint of curiosity as to what has brought me here."

"I take the gifts of the gods, you see, and ask no questions," said Thorndyke.

"Devilish handsome of you, Thorndyke—unsociable beggar like you, too," rejoined Mr. Brodribb, a fan of wrinkles spreading out genially from the corners of his eyes; "but the fact is I have come, in a sense, on business—always glad of a pretext to look you up, as you know—but I want to take your opinion on a rather queer case. It is about young Calverley. You remember Horace Calverley? Well, this is his son. Horace and I were schoolmates, you know, and after his death the boy, Fred, hung on to me rather. We're near neighbours down at Weybridge, and very good friends. I like Fred. He's a good fellow, though cranky, like all his people."

"What has happened to Fred Calverley?" Thorndyke asked, as the solicitor paused.

"Why, the fact is," said Mr. Brodribb, "just lately he seems to be going a bit queer—not mad, mind you—at least, I think not—but undoubtedly queer. Now, there is a good deal of property, and a good many highly interested relatives, and, as a natural consequence, there is some talk of getting him certified. They're afraid he may do something involving the estate or develop homicidal tendencies, and they talk of possible suicide—you remember his father's death—but I say that's all bunkum. The fellow is just a bit cranky, and nothing more."

"What are his symptoms?" asked Thorndyke.

"Oh, he thinks he is being followed about and watched, and he has delusions; sees himself in the glass with the wrong face, and that sort of thing, you know."

"You are not highly circumstantial," Thorndyke remarked.

Mr. Brodribb looked at me with a genial smile.

"What a glutton for facts this fellow is, Jervis. But you're right, Thorndyke; I'm vague. However, Fred will be here presently. We travel down together, and I took the liberty of asking him to call for me. We'll get him to tell you about his delusions, if you don't mind. He's not shy about them. And meanwhile I'll give you a few preliminary facts. The trouble began about a year ago. He was in a railway accident, and that knocked him all to pieces. Then he went for a voyage to recruit, and the ship broke her propeller-shaft in a storm and became helpless. That didn't improve the state of his nerves. Then he went down the Mediterranean, and after a month or two, back he came, no better than when he started. But here he is, I expect."

He went over to the door and admitted a tall, frail young man whom Thorndyke welcomed with quiet geniality, and settled in a chair by the fire. I looked curiously at our visitor. He was a typical neurotic—slender, fragile, eager. Wide-open blue eyes with broad pupils, in which I could plainly see the characteristic "hippus"—that incessant change of size that marks the unstable nervous equilibrium—parted lips, and wandering taper fingers, were as the stigmata of his disorder. He was of the stuff out of which prophets and devotees, martyrs, reformers, and third-rate poets are made.

"I have been telling Dr. Thorndyke about these nervous troubles of yours," said Mr. Brodribb presently. "I hope you don't mind. He is an old friend, you know, and he is very much interested."

"It is very good of him," said Calverley. Then he flushed deeply, and added: "But they are not really nervous, you know. They can't be merely subjective."

"You think they can't be?" said Thorndyke.

"No, I am sure they are not." He flushed again like a girl, and looked earnestly at Thorndyke with his big, dreamy eyes. "But you doctors," he said, "are so dreadfully sceptical of all spiritual phenomena. You are such materialists."

"Yes," said Mr. Brodribb; "the doctors are not hot on the supernatural, and that's the fact."

"Supposing you tell us about your experiences," said Thorndyke persuasively. "Give us a chance to believe, if we can't explain away."

Calverley reflected for a few moments; then, looking earnestly at Thorndyke, he said:

"Very well; if it won't bore you, I will. It is a curious story."

"I have told Dr. Thorndyke about your voyage and your trip down the Mediterranean," said Mr. Brodribb.

"Then," said Calverley, "I will begin with the events that are actually connected with these strange visitations. The first of these occurred in Marseilles. I was in a curio-shop there, looking over some Algerian and Moorish tilings, when my attention was attracted by a sort of charm or pendant that hung in a glass case. It was not particularly beautiful, but its appearance was quaint and curious, and took my fancy. It consisted of an oblong block of ebony in which was set a single pear-shaped pearl more than three-quarters of an inch long. The sides of the ebony block were lacquered—probably to conceal a joint—and bore a number of Chinese characters, and at the top was a little gold image with a hole through it, presumably for a string to suspend it by. Excepting for the pearl, the whole thing was uncommonly like one of those ornamental tablets of Chinese ink.

"Now, I had taken a fancy to the thing, and I can afford to indulge my fancies in moderation. The man wanted five pounds for it; he assured me that the pearl was a genuine one of fine quality, and obviously did not believe it himself. To me, however, it looked like a real pearl, and I determined to take the risk; so I paid the money, and he bowed me out with a smile—I may almost say a grin—of satisfaction. He would not have been so well pleased if he had followed me to a jeweller's to whom I took it for an expert opinion; for the jeweller pronounced the pearl to be undoubtedly genuine, and worth anything up to a thousand pounds.

"A day or two later, I happened to show my new purchase to some men whom I knew, who had dropped in at Marseilles in their yacht. They were highly amused at my having bought the thing, and when I told them what I had paid for it, they positively howled with derision.

"'Why, you silly guffin,' said one of them, a man named Halliwell, 'I could have had it ten days ago for half a sovereign, or probably five shillings. I wish now I had bought it; then I could have sold it to you.'

"It seemed that a sailor had been hawking the pendant round the harbour, and had been on board the yacht with it.

"'Deuced anxious the beggar was to get rid of it, too,' said Halliwell, grinning at the recollection. 'Swore it was a genuine pearl of priceless value, and was willing to deprive himself of it for the trifling sum of half a jimmy. But we'd heard that sort of thing before. However, the curio-man seems to have speculated on the chance of meeting with a greenhorn, and he seems to have pulled it off. Lucky curio man!'

"I listened patiently to their gibes, and when they had talked themselves out I told them about the jeweller. They were most frightfully sick; and when we had taken the pendant to a dealer in gems who happened to be staying in the town, and he had offered me five hundred pounds for it, their language wasn't fit for a divinity students' debating club. Naturally the story got noised abroad, and when I left, it was the talk of the place. The general opinion was that the sailor, who was traced to a tea-ship that had put into the harbour, had stolen it from some Chinese passenger; and no less than seventeen different Chinamen came forward to claim it as their stolen property.

"Soon after this I returned to England, and, as my nerves were still in a very shaky state, I came to live with my cousin Alfred, who has a large house at Weybridge. At this time he had a friend staying with him, a certain Captain Raggerton, and the two men appeared to be on very intimate terms. I did not take to Raggerton at all. He was a good-looking man, pleasant in his manners, and remarkably plausible. But the fact is—I am speaking in strict confidence, of course—he was a bad egg. He had been in the Guards, and I don't quite know why he left; but I do know that he played bridge and baccarat pretty heavily at several clubs, and that he had a reputation for being a rather uncomfortably lucky player. He did a good deal at the race-meetings, too, and was in general such an obvious undesirable that I could never understand my cousin's intimacy with him, though I must say that Alfred's habits had changed somewhat for the worse since I had left England.

"The fame of my purchase seems to have preceded me, for when, one day, I produced the pendant to show them, I found that they knew all about it. Raggerton had heard the story from a naval man, and I gathered vaguely that he had heard something that I had not, and that he did not care to tell me; for when my cousin and he talked about the pearl, which they did pretty often, certain significant looks passed between them, and certain veiled references were made which I could not fail to notice.

"One day I happened to be telling them of a curious incident that occurred on my way home. I had travelled to England on one of Holt's big China boats, not liking the crowd and bustle of the regular passenger-lines. Now, one afternoon, when we had been at sea a couple of days, I took a book down to my berth, intending to have a quiet read till tea-time. Soon, however, I dropped off into a doze, and must have remained asleep for over an hour. I awoke suddenly, and as I opened my eyes, I perceived that the door of the state-room was half-open, and a well-dressed Chinaman, in native costume, was looking in at me. He closed the door immediately, and I remained for a few moments paralyzed by the start that he had given me. Then I leaped from my bunk, opened the door, and looked out. But the alley-way was empty. The Chinaman had vanished as if by magic.

"This little occurrence made me quite nervous for a day or two, which was very foolish of me; but my nerves were all on edge—and I am afraid they are still."

"Yes," said Thorndyke. "There was nothing mysterious about the affair. These boats carry a Chinese crew, and the man you saw was probably a Serang, or whatever they call the gang-captains on these vessels. Or he may have been a native passenger who had strayed into the wrong part of the ship."

"Exactly," agreed our client. "But to return to Raggerton. He listened with quite extraordinary interest as I was telling this story, and when I had finished he looked very queerly at my cousin.

"'A deuced odd thing, this, Calverley,' said he. 'Of course, it may be only a coincidence, but it really does look as if there was something, after all, in that—'

"'Shut up, Raggerton,' said my cousin. 'We don't want any of that rot.'

"'What is he talking about?" I asked.

"'Oh, it's only a rotten, silly yarn that he has picked up somewhere. You're not to tell him, Raggerton.'

"'I don't see why I am not to be told,' I said, rather sulkily. 'I'm not a baby.'

"'No,' said Alfred, 'but you're an invalid. You don't want any horrors.'

"In effect, he refused to go into the matter any further, and I was left on tenter-hooks of curiosity.

"However, the very next day I got Raggerton alone in the smoking-room, and had a little talk with him. He had just dropped a hundred pounds on a double event that hadn't come off, and I expected to find him pliable. Nor was I disappointed, for, when we had negotiated a little loan, he was entirely at my service, and willing to tell me everything, on my promising not to give him away to Alfred.

"'Now, you understand,' he said, 'that this yarn about your pearl is nothing but a damn silly fable that's been going the round in Marseilles. I don't know where it came from, or what sort of demented rotter invented it; I had it from a Johnnie in the Mediterranean Squadron, and you can have a copy of his letter if you want it.'

"I said that I did want it. Accordingly, that same evening he handed me a copy of the narrative extracted from his friend's letter, the substance of which was this:

"About four months ago there was lying in Canton Harbour a large English barque. Her name is not mentioned, but that is not material to the story. She had got her cargo stowed and her crew signed on, and was only waiting for certain official formalities to be completed before putting to sea on her homeward voyage. Just ahead of her, at the same quay, was a Danish ship that had been in collision outside, and was now laid up pending the decision of the Admiralty Court. She had been unloaded, and her crew paid off, with the exception of one elderly man, who remained on board as ship-keeper. Now, a considerable part of the cargo of the English barque was the property of a certain wealthy mandarin, and this person had been about the vessel a good deal while she was taking in her lading.

"One day, when the mandarin was on board the barque, it happened that three of the seamen were sitting in the galley smoking and chatting with the cook—an elderly Chinaman named Wo-li—and the latter, pointing out the mandarin to the sailors, expatiated on his enormous wealth, assuring them that he was commonly believed to carry on his person articles of sufficient value to buy up the entire lading of a ship.

"Now, unfortunately for the mandarin, it chanced that these three sailors were about the greatest rascals on board; which is saying a good deal when one considers the ordinary moral standard that prevails in the forecastle of a sailing-ship. Nor was Wo-li himself an angel; in fact, he was a consummate villain, and seems to have been the actual originator of the plot which was presently devised to rob the mandarin.

"This plot was as remarkable for its simplicity as for its cold-blooded barbarity. On the evening before the barque sailed, the three seamen, Nilsson, Foucault, and Parratt, proceeded to the Danish ship with a supply of whisky, made the ship-keeper royally drunk, and locked him up in an empty berth. Meanwhile Wo-li made a secret communication to the mandarin to the effect that certain stolen property, believed to be his, had been secreted in the hold of the empty ship. Thereupon the mandarin came down hot-foot to the quay-side, and was received on board by the three seamen, who had got the covers off the after-hatch in readiness. Parratt now ran down the iron ladder to show the way, and the mandarin followed; but when they reached the lower deck, and looked down the hatch into the black darkness of the lower hold, he seems to have taken fright, and begun to climb up again. Meanwhile Nilsson had made a running bowline in the end of a loose halyard that was rove through a block aloft, and had been used for hoisting out the cargo. As the mandarin came up, he leaned over the coaming of the hatch, dropped the noose over the Chinaman's head, jerked it tight, and then he and Foucault hove on the fall of the rope. The unfortunate Chinaman was dragged from the ladder, and, as he swung clear, the two rascals let go the rope, allowing him to drop through the hatches into the lower hold. Then they belayed the rope, and went down below. Parratt had already lighted a slush-lamp, by the glimmer of which they could see the mandarin swinging to and fro like a pendulum within a few feet of the ballast, and still quivering and twitching in his death-throes. They were now joined by Wo-li, who had watched the proceedings from the quay, and the four villains proceeded, without loss of time, to rifle the body as it hung. To their surprise and disgust, they found nothing of value excepting an ebony pendant set with a single large pearl; but Wo-li, though evidently disappointed at the nature of the booty, assured his comrades that this alone was well worth the hazard, pointing out the great size and exceptional beauty of the pearl. As to this, the seamen know nothing about pearls, but the thing was done, and had to be made the best of; so they made the rope fast to the lower deck-beams, cut off the remainder and unrove it from the block, and went back to their ship.

"It was twenty-four hours before the ship-keeper was sufficiently sober to break out of the berth in which he had been locked, by which time the barque was well out to sea; and it was another three days before the body of the mandarin was found. An active search was then made for the murderers, but as they were strangers to the ship-keeper, no clues to their whereabouts could be discovered.

"Meanwhile, the four murderers were a good deal exercised as to the disposal of the booty. Since it could not be divided, it was evident that it must be entrusted to the keeping of one of them. The choice in the first place fell upon Wo-li, in whose chest the pendant was deposited as soon as the party came on board, it being arranged that the Chinaman should produce the jewel for inspection by his confederates whenever called upon.

"For six weeks nothing out of the common occurred; but then a very singular event befell. The four conspirators were sitting outside the galley one evening, when suddenly the cook uttered a cry of amazement and horror. The other three turned to see what it was that had so disturbed their comrade, and then they, too, were struck dumb with consternation; for, standing at the door of the companion-hatch—the barque was a flush-decked vessel—was the mandarin whom they had left for dead. He stood quietly regarding them for fully a minute, while they stared at him transfixed with terror. Then he beckoned to them, and went below.

"So petrified were they with astonishment and mortal fear that they remained for a long time motionless and dumb. At last they plucked up courage, and began to make furtive inquiries among the crew; but no one—not even the steward—knew anything of any passengers, or, indeed, of any Chinaman, on board the ship, excepting Wo-li.

"At day-break the next morning, when the cook's mate went to the galley to fill the coppers, he found Wo-li hanging from a hook in the ceiling. The cook's body was stiff and cold, and had evidently been hanging several hours. The report of the tragedy quickly spread through the ship, and the three conspirators hurried off to remove the pearl from the dead man's chest before the officers should come to examine it. The cheap lock was easily picked with a bent wire, and the jewel abstracted; but now the question arose as to who should take charge of it. The eagerness to be the actual custodian of the precious bauble, which had been at first displayed, now gave place to equally strong reluctance. But someone had to take charge of it, and after a long and angry discussion Nilsson was prevailed upon to stow it in his chest.

"A fortnight passed. The three conspirators went about their duties soberly, like men burdened with some secret anxiety, and in their leisure moments they would sit and talk with bated breath of the apparition at the companion-hatch, and the mysterious death of their late comrade.

"At last the blow fell.

"It was at the end of the second dog-watch that the hands were gathered on the forecastle, preparing to make sail after a spell of bad weather. Suddenly Nilsson gave a husky shout, and rushed at Parratt, holding out the key of his chest.

"'Here you, Parratt,' he exclaimed, 'go below and take that accursed thing out of my chest.'

"'What for?' demanded Parratt; and then he and Foucault, who was standing close by, looked aft to see what Nilsson was staring at.

"Instantly they both turned white as ghosts, and fell trembling so that they could hardly stand; for there was the mandarin, standing calmly by the companion, returning with a steady, impassive gaze their looks of horror. And even as they looked he beckoned and went below.

"'D'ye hear, Parratt?' gasped Nilsson; 'take my key and do what I say, or else—'

"But at this moment the order was given to go aloft and set all plain sail; the three men went off to their respective posts, Nilsson going up the fore-topmast rigging, and the other two to the main-top. Having finished their work aloft, Foucault and Parratt who were both in the port watch, came down on deck, and then, it being their watch below, they went and turned in.

"When they turned out with their watch at midnight, they looked about for Nilsson, who was in the starboard watch, but he was nowhere to be seen. Thinking he might have slipped below unobserved, they made no remark, though they were very uneasy about him; but when the starboard watch came on deck at four o'clock, and Nilsson did not appear with his mates, the two men became alarmed, and made inquiries about him. It was now discovered that no one had seen him since eight o'clock on the previous evening, and, this being reported to the officer of the watch, the latter ordered all hands to be called. But still Nilsson did not appear. A thorough search was now instituted, both below and aloft, and as there was still no sign of the missing man, it was concluded that he had fallen overboard.

"But at eight o'clock two men were sent aloft to shake out the fore-royal. They reached the yard almost simultaneously, and were just stepping on to the foot-ropes when one of them gave a shout; then the pair came sliding down a backstay, with faces as white as tallow. As soon as they reached the deck, they took the officer of the watch forward, and, standing on the heel of the bowsprit, pointed aloft. Several of the hands, including Foucault and Parratt, had followed, and all looked up; and there they saw the body of Nilsson, hanging on the front of the fore-topgallant sail. He was dangling at the end of a gasket, and bouncing up and down on the taut belly of the sail as the ship rose and fell to the send of the sea.

"The two survivors were now in some doubt about having anything further to do with the pearl. But the great value of the jewel, and the consideration that it was now to be divided between two instead of four, tempted them. They abstracted it from Nilsson's chest, and then, as they could not come to an agreement in any other way, they decided to settle who should take charge of it by tossing a coin. The coin was accordingly spun, and the pearl went to Foucault's chest.

"From this moment Foucault lived in a state of continual apprehension. When on deck, his eyes were for ever wandering towards the companion hatch, and during his watch below, when not asleep, he would sit moodily on his chest, lost in gloomy reflection. But a fortnight passed, then three weeks, and still nothing happened. Land was sighted, the Straits of Gibraltar passed, and the end of the voyage was but a matter of days. And still the dreaded mandarin made no sign.

"At length the ship was within twenty-four hours of Marseilles, to which port a large part of the cargo was consigned. Active preparations were being made for entering the port, and among other things the shore tackle was being overhauled. A share in this latter work fell to Foucault and Parratt, and about the middle of the second dog-watch—seven o'clock in the evening—they were sitting on the deck working an eye-splice in the end of a large rope. Suddenly Foucault, who was facing forward, saw his companion turn pale and stare aft with an expression of terror. He immediately turned and looked over his shoulder to see what Parratt was staring at. It was the mandarin, standing by the companion, gravely watching them; and as Foucault turned and met his gaze, the Chinaman beckoned and went below.

"For the rest of that day Parratt kept close to his terrified comrade, and during their watch below he endeavoured to remain awake, that he might keep his friend in view. Nothing happened through the night, and the following morning, when they came on deck for the forenoon watch, their port was well in sight. The two men now separated for the first time, Parratt going aft to take his trick at the wheel, and Foucault being set to help in getting ready the ground tackle.

"Half an hour later Parratt saw the mate stand on the rail and lean outboard, holding on to the mizzen-shrouds while he stared along the ship's side. Then he jumped on to the deck and shouted angrily: 'Forward, there! What the deuce is that man up to under the starboard cat-head?'

"The men on the forecastle rushed to the side and looked over; two of them leaned over the rail with the bight of a rope between them, and a third came running aft to the mate. 'It's Foucault, sir,' Parratt heard him say. 'He's hanged hisself from the cat-head.'

"As soon as he was off duty, Parratt made his way to his dead comrade's chest, and, opening it with his pick-lock, took out the pearl. It was now his sole property, and, as the ship was within an hour or two of her destination, he thought he had little to fear from its murdered owner. As soon as the vessel was alongside the wharf, he would slip ashore and get rid of the jewel, even if he sold it at a comparatively low price. The thing looked perfectly simple.

"In actual practice, however, it turned out quite otherwise. He began by accosting a well-dressed stranger and offering the pendant for fifty pounds; but the only reply that he got was a knowing smile and a shake of the head. When this experience had been repeated a dozen times or more, and he had been followed up and down the streets for nearly an hour by a suspicious gendarme, he began to grow anxious. He visited quite a number of ships and yachts in the harbour, and at each refusal the price of his treasure came down, until he was eager to sell it for a few francs. But still no one would have it. Everyone took it for granted that the pearl was a sham, and most of the persons whom he accosted assumed that it had been stolen. The position was getting desperate. Evening was approaching—the time of the dreaded dog-watches—and still the pearl was in his possession. Gladly would he now have given it away for nothing, but he dared not try, for this would lay him open to the strongest suspicion.

"At last, in a by-street, he came upon the shop of a curio-dealer. Putting on a careless and cheerful manner, he entered and offered the pendant for ten francs. The dealer looked at it, shook his head, and handed it back.

"'What will you give me for it?' demanded Parratt, breaking out into a cold sweat at the prospect of a final refusal.

"The dealer felt in his pocket, drew out a couple of francs, and held them out.

"'Very well,' said Parratt. He took the money as calmly as he could, and marched out of the shop, with a gasp of relief, leaving the pendant in the dealer's hand.

"The jewel was hung up in a glass case, and nothing more was thought about it until some ten days later, when an English tourist, who came into the shop, noticed it and took a liking to it. Thereupon the dealer offered it to him for five pounds, assuring him that it was a genuine pearl, a statement that, to his amazement, the stranger evidently believed. He was then deeply afflicted at not having asked a higher price, but the bargain had been struck, and the Englishman went off with his purchase.

"This was the story told by Captain Raggerton's friend, and I have given it to you in full detail, having read the manuscript over many times since it was given to me. No doubt you will regard it as a mere traveller's tale, and consider me a superstitious idiot for giving any credence to it."

"It certainly seems more remarkable for picturesqueness than for credibility," Thorndyke agreed. "May I ask," he continued, "whether Captain Raggerton's friend gave any explanation as to how this singular story came to his knowledge, or to that of anybody else?"

"Oh yes," replied Calverley; "I forgot to mention that the seaman, Parratt, very shortly after he had sold the pearl, fell down the hatch into the hold as the ship was unloading, and was very badly injured. He was taken to the hospital, where he died on the following day; and it was while he was lying there in a dying condition that he confessed to the murder, and gave this circumstantial account of it."

"I see," said Thorndyke; "and I understand that you accept the story as literally true?"

"Undoubtedly." Calverley flushed defiantly as he returned Thorndyke's look, and continued: "You see, I am not a man of science: therefore my beliefs are not limited to things that can be weighed and measured. There are things, Dr. Thorndyke, which are outside the range of our puny intellects; things that science, with its arrogant materialism, puts aside and ignores with close-shut eyes. I prefer to believe in things which obviously exist, even though I cannot explain them. It is the humbler and, I think, the wiser attitude."

"But, my dear Fred," protested Mr. Brodribb, "this is a rank fairy-tale."

Calverley turned upon the solicitor. "If you had seen what I have seen, you would not only believe: you would know."

"Tell us what you have seen, then," said Mr. Brodribb.

"I will, if you wish to hear it," said Calverley. "I will continue the strange history of the Mandarin's Pearl."

He lit a fresh cigarette and continued:

"The night I came to Beech-hurst—that is my cousin's house, you know—a rather absurd thing happened, which I mention on account of its connection with what has followed. I had gone to my room early, and sat for some time writing letters before getting ready for bed. When I had finished my letters, I started on a tour of inspection of my room. I was then, you must remember, in a very nervous state, and it had become my habit to examine the room in which I was to sleep before undressing, looking under the bed, and in any cupboards and closets that there happened to be. Now, on looking round my new room, I perceived that there was a second door, and I at once proceeded to open it to see where it led to. As soon as I opened the door, I got a terrible start. I found myself looking into a narrow closet or passage, lined with pegs, on which the servant had hung some of my clothes; at the farther end was another door, and, as I stood looking into the closet, I observed, with startled amazement, a man standing holding the door half-open, and silently regarding me. I stood for a moment staring at him, with my heart thumping and my limbs all of a tremble; then I slammed the door and ran off to look for my cousin.

"He was in the billiard-room with Raggerton, and the pair looked up sharply as I entered.

"'Alfred,' I said, 'where does that passage lead to out of my room?'

"'Lead to?' said he. 'Why, it doesn't lead anywhere. It used to open into a cross corridor, but when the house was altered, the corridor was done away with, and this passage closed up. It is only a cupboard now.'

"'Well, there's a man in it—or there was just now.'

"'Nonsense!' he exclaimed; 'impossible! Let us go and look at the place.'

"He and Raggerton rose, and we went together to my room. As we flung open the door of the closet and looked in, we all three burst into a laugh. There were three men now looking at us from the open door at the other end, and the mystery was solved. A large mirror had been placed at the end of the closet to cover the partition which cut it off from the cross corridor.

"This incident naturally exposed me to a good deal of chaff from my cousin and Captain Raggerton; but I often wished that the mirror had not been placed there, for it happened over and over again that, going to the cupboard hurriedly, and not thinking of the mirror, I got quite a bad shock on being confronted by a figure apparently coming straight at me through an open door. In fact, it annoyed me so much, in my nervous state, that I even thought of asking my cousin to give me a different room; but, happening to refer to the matter when talking to Raggerton, I found the Captain so scornful of my cowardice that my pride was touched, and I let the affair drop.



"And now I come to a very strange occurrence, which I shall relate quite frankly, although I know beforehand that you will set me down as a liar or a lunatic. I had been away from home for a fortnight, and as I returned rather late at night, I went straight to my room. Having partly undressed, I took my clothes in one hand and a candle in the other, and opened the cupboard door. I stood for a moment looking nervously at my double, standing, candle in hand, looking at me through the open door at the other end of the passage; then I entered, and, setting the candle on a shelf, proceeded to hang up my clothes. I had hung them up, and had just reached up for the candle, when my eye was caught by something strange in the mirror. It no longer reflected the candle in my hand, but instead of it, a large coloured paper lantern. I stood petrified with astonishment, and gazed into the mirror; and then I saw that my own reflection was changed, too; that, in place of my own figure, was that of an elderly Chinaman, who stood regarding me with stony calm.

"I must have stood for near upon a minute, unable to move and scarce able to breathe, face to face with that awful figure. At length I turned to escape, and, as I turned, he turned also, and I could see him, over my shoulder, hurrying away. As I reached the door, I halted for a moment, looking back with the door in my hand, holding the candle above my head; and even so he halted, looking back at me, with his hand upon the door and his lantern held above his head.

"I was so much upset that I could not go to bed for some hours, but continued to pace the room, in spite of my fatigue. Now and again I was impelled, irresistibly, to peer into the cupboard, but nothing was to be seen in the mirror save my own figure, candle in hand, peeping in at me through the half-open door. And each time that I looked into my own white, horror-stricken face, I shut the door hastily and turned away with a shudder; for the pegs, with the clothes hanging on them, seemed to call to me. I went to bed at last, and before I fell asleep I formed the resolution that, if I was spared until the next day, I would write to the British Consul at Canton, and offer to restore the pearl to the relatives of the murdered mandarin.

"On the following day I wrote and despatched the letter, after which I felt more composed, though I was haunted continually by the recollection of that stony, impassive figure; and from time to time I felt an irresistible impulse to go and look in at the door of the closet, at the mirror and the pegs with the clothes hanging from them. I told my cousin of the visitation that I had received, but he merely laughed, and was frankly incredulous; while the Captain bluntly advised me not to be a superstitious donkey.

"For some days after this I was left in peace, and began to hope that my letter had appeased the spirit of the murdered man; but on the fifth day, about six o'clock in the evening, happening to want some papers that I had left in the pocket of a coat which was hanging in the closet, I went in to get them. I took in no candle, as it was not yet dark, but left the door wide open to light me. The coat that I wanted was near the end of the closet, not more than four paces from the mirror, and as I went towards it I watched my reflection rather nervously as it advanced to meet me. I found my coat, and as I felt for the papers, I still kept a suspicious eye on my double. And, even as I looked, a most strange phenomenon appeared: the mirror seemed for an instant to darken or cloud over, and then, as it cleared again, I saw, standing dark against the light of the open door behind him, the figure of the mandarin. After a single glance, I ran out of the closet, shaking with agitation; but as I turned to shut the door, I noticed that it was my own figure that was reflected in the glass. The Chinaman had vanished in an instant.

"It now became evident that my letter had not served its purpose, and I was plunged in despair; the more so since, on this day, I felt again the dreadful impulse to go and look at the pegs on the walls of the closet. There was no mistaking the meaning of that impulse, and each time that I went, I dragged myself away reluctantly, though shivering with horror. One circumstance, indeed, encouraged me a little; the mandarin had not, on either occasion, beckoned to me as he had done to the sailors, so that perhaps some way of escape yet lay open to me.

"During the next few days I considered very earnestly what measures I could take to avert the doom that seemed to be hanging over me. The simplest plan, that of passing the pearl on to some other person, was out of the question; it would be nothing short of murder. On the other hand, I could not wait for an answer to my letter; for even if I remained alive, I felt that my reason would have given way long before the reply reached me. But while I was debating what I should do, the mandarin appeared to me again; and then, after an interval of only two days, he came to me once more. That was last night. I remained gazing at him, fascinated, with my flesh creeping, as he stood, lantern in hand, looking steadily in my face. At last he held out his hand to me, as if asking me to give him the pearl; then the mirror darkened, and he vanished in a flash; and in the place where he had stood there was my own reflection looking at me out of the glass.

"That last visitation decided me. When I left home this morning the pearl was in my pocket, and as I came over Waterloo Bridge, I leaned over the parapet and flung the thing into the water. After that I felt quite relieved for a time; I had shaken the accursed thing off without involving anyone in the curse that it carried. But presently I began to feel fresh misgivings, and the conviction has been growing upon me all day that I have done the wrong thing. I have only placed it for ever beyond the reach of its owner, whereas I ought to have burnt it, after the Chinese fashion, so that its non-material essence could have joined the spiritual body of him to whom it had belonged when both were clothed with material substance.

"But it can't be altered now. For good or for evil, the thing is done, and God alone knows what the end of it will be."

As he concluded, Calverley uttered a deep sigh, and covered his face with his slender, delicate hands. For a space we were all silent and, I think, deeply moved; for, grotesquely unreal as the whole thing was, there was a pathos, and even a tragedy, in it that we all felt to be very real indeed.

Suddenly Mr. Brodribb started and looked at his watch.

"Good gracious, Calverley, we shall lose our train."

The young man pulled himself together and stood up. "We shall just do it if we go at once," said he. "Good-bye," he added, shaking Thorndyke's hand and mine. "You have been very patient, and I have been rather prosy, I am afraid. Come along, Mr. Brodribb."

Thorndyke and I followed them out on to the landing, and I heard my colleague say to the solicitor in a low tone, but very earnestly: "Get him away from that house, Brodribb, and don't let him out of your sight for a moment."

I did not catch the solicitor's reply, if he made any, but when we were back in our room I noticed that Thorndyke was more agitated than I had ever seen him.

"I ought not to have let them go," he exclaimed. "Confound me! If I had had a grain of wit, I should have made them lose their train."

He lit his pipe and fell to pacing the room with long strides, his eyes bent on the floor with an expression sternly reflective. At last, finding him hopelessly taciturn, I knocked out my pipe and went to bed.

* * * * *

As I was dressing on the following morning, Thorndyke entered my room. His face was grave even to sternness, and he held a telegram in his hand.

"I am going to Weybridge this morning," he said shortly, holding the "flimsy" out to me. "Shall you come?"

I took the paper from him, and read:

"Come, for God's sake! F. C. is dead. You will understand.—BRODRIBB."

I handed him back the telegram, too much shocked for a moment to speak. The whole dreadful tragedy summed up in that curt message rose before me in an instant, and a wave of deep pity swept over me at this miserable end to the sad, empty life.

"What an awful thing, Thorndyke!" I exclaimed at length. "To be killed by a mere grotesque delusion."

"Do you think so?" he asked dryly. "Well, we shall see; but you will come?"

"Yes," I replied; and as he retired, I proceeded hurriedly to finish dressing.

Half an hour later, as we rose from a rapid breakfast, Polton came into the room, carrying a small roll-up case of tools and a bunch of skeleton keys.

"Will you have them in a bag, sir?" he asked.

"No," replied Thorndyke; "in my overcoat pocket. Oh, and here is a note, Polton, which I want you to take round to Scotland Yard. It is to the Assistant Commissioner, and you are to make sure that it is in the right hands before you leave. And here is a telegram to Mr. Brodribb."

He dropped the keys and the tool-case into his pocket, and we went down together to the waiting hansom.

At Weybridge Station we found Mr. Brodribb pacing the platform in a state of extreme dejection. He brightened up somewhat when he saw us, and wrung our hands with emotional heartiness.

"It was very good of you both to come at a moment's notice," he said warmly, "and I feel your kindness very much. You understood, of course, Thorndyke?"

"Yes," Thorndyke replied. "I suppose the mandarin beckoned to him."

Mr. Brodribb turned with a look of surprise. "How did you guess that?" he asked; and then, without waiting for a reply, he took from his pocket a note, which he handed to my colleague. "The poor old fellow left this for me," he said. "The servant found it on his dressing-table."

Thorndyke glanced through the note and passed it to me. It consisted of but a few words, hurriedly written in a tremulous hand.

"He has beckoned to me, and I must go. Good-bye, dear old friend."

"How does his cousin take the matter?" asked Thorndyke.

"He doesn't know of it yet," replied the lawyer. "Alfred and Raggerton went out after an early breakfast, to cycle over to Guildford on some business or other, and they have not returned yet. The catastrophe was discovered soon after they left. The maid went to his room with a cup of tea, and was astonished to find that his bed had not been slept in. She ran down in alarm and reported to the butler, who went up at once and searched the room; but he could find no trace of the missing one, except my note, until it occurred to him to look in the cupboard. As he opened the door he got rather a start from his own reflection in the mirror; and then he saw poor Fred hanging from one of the pegs near the end of the closet, close to the glass. It's a melancholy affair—but here is the house, and here is the butler waiting for us. Mr. Alfred is not back yet, then, Stevens?"

"No, sir." The white-faced, frightened-looking man had evidently been waiting at the gate from distaste of the house, and he now walked back with manifest relief at our arrival. When we entered the house, he ushered us without remark up on to the first-floor, and, preceding us along a corridor, halted near the end. "That's the room, sir," said he; and without another word he turned and went down the stairs.

We entered the room, and Mr. Brodribb followed on tiptoe, looking about him fearfully, and casting awe-struck glances at the shrouded form on the bed. To the latter Thorndyke advanced, and gently drew back the sheet.

"You'd better not look, Brodribb," said he, as he bent over the corpse. He felt the limbs and examined the cord, which still remained round the neck, its raggedly-severed end testifying to the terror of the servants who had cut down the body. Then he replaced the sheet and looked at his watch. "It happened at about three o'clock in the morning," said he. "He must have struggled with the impulse for some time, poor fellow! Now let us look at the cupboard."

We went together to a door in the corner of the room, and, as we opened it, we were confronted by three figures, apparently looking in at us through an open door at the other end.

"It is really rather startling," said the lawyer, in a subdued voice, looking almost apprehensively at the three figures that advanced to meet us. "The poor lad ought never to have been here."

It was certainly an eerie place, and I could not but feel, as we walked down the dark, narrow passage, with those other three dimly-seen figures silently coming towards us, and mimicking our every gesture, that it was no place for a nervous, superstitious man like poor Fred Calverley. Close to the end of the long row of pegs was one from which hung an end of stout box-cord, and to this Mr. Brodribb pointed with an awe-struck gesture. But Thorndyke gave it only a brief glance, and then walked up to the mirror, which he proceeded to examine minutely. It was a very large glass, nearly seven feet high, extending the full width of the closet, and reaching to within a foot of the floor; and it seemed to have been let into the partition from behind, for, both above and below, the woodwork was in front of it. While I was making these observations, I watched Thorndyke with no little curiosity. First he rapped his knuckles on the glass; then he lighted a wax match, and, holding it close to the mirror, carefully watched the reflection of the flame. Finally, laying his cheek on the glass, he held the match at arm's length, still close to the mirror, and looked at the reflection along the surface. Then he blew out the match and walked back into the room, shutting the cupboard door as we emerged.

"I think," said he, "that as we shall all undoubtedly be subpoenaed by the coroner, it would be well to put together a few notes of the facts. I see there is a writing-table by the window, and I would propose that you, Brodribb, just jot down a precis of the statement that you heard last night, while Jervis notes down the exact condition of the body. While you are doing this, I will take a look round."

"We might find a more cheerful place to write in," grumbled Mr. Brodribb; "however—"

Without finishing the sentence, he sat down at the table, and, having found some sermon paper, dipped a pen in the ink by way of encouraging his thoughts. At this moment Thorndyke quietly slipped out of the room, and I proceeded to make a detailed examination of the body: in which occupation I was interrupted at intervals by requests from the lawyer that I should refresh his memory.

We had been occupied thus for about a quarter of an hour, when a quick step was heard outside, the door was opened abruptly, and a man burst into the room. Brodribb rose and held out his hand.

"This is a sad home-coming for you, Alfred," said he.

"Yes, my God!" the newcomer exclaimed. "It's awful."

He looked askance at the corpse on the bed, and wiped his forehead with his handkerchief. Alfred Calverley was not extremely prepossessing. Like his cousin, he was obviously neurotic, but there were signs of dissipation in his face, which, just now, was pale and ghastly, and wore an expression of abject fear. Moreover, his entrance was accompanied by that of a perceptible odour of brandy.

He had walked over, without noticing me, to the writing-table, and as he stood there, talking in subdued tones with the lawyer, I suddenly found Thorndyke at my side. He had stolen in noiselessly through the door that Calverley had left open.

"Show him Brodribb's note," he whispered, "and then make him go in and look at the peg."

With this mysterious request, he slipped out of the room as silently as he had come, unperceived either by Calverley or the lawyer.

"Has Captain Raggerton returned with you?" Brodribb was inquiring.

"No, he has gone into the town," was the reply; "but he won't be long. This will be a frightful shock to him."

At this point I stepped forward. "Have you shown Mr. Calverley the extraordinary letter that the deceased left for you?" I asked.

"What letter was that?" demanded Calverley, with a start.

Mr. Brodribb drew forth the note and handed it to him. As he read it through, Calverley turned white to the lips, and the paper trembled in his hand.

"'He has beckoned to me, and I must go,'" he read. Then, with a furtive glance at the lawyer: "Who had beckoned? What did he mean?"

Mr. Brodribb briefly explained the meaning of the allusion, adding: "I thought you knew all about it."

"Yes, yes," said Calverley, with some confusion; "I remember the matter now you mention it. But it's all so dreadful and bewildering."

At this point I again interposed. "There is a question," I said, "that may be of some importance. It refers to the cord with which the poor fellow hanged himself. Can you identify that cord, Mr. Calverley?"

"I!" he exclaimed, staring at me, and wiping the sweat from his white face; "how should I? Where is the cord?"

"Part of it is still hanging from the peg in the closet. Would you mind looking at it?"

"If you would very kindly fetch it—you know I—er—naturally—have a—"

"It must not be disturbed before the inquest," said I; "but surely you are not afraid—"

"I didn't say I was afraid," he retorted angrily. "Why should I be?"

With a strange, tremulous swagger, he strode across to the closet, flung open the door, and plunged in.

A moment later we heard a shout of horror, and he rushed out, livid and gasping.

"What is it, Calverley?" exclaimed Mr. Brodribb, starting up in alarm.

But Calverley was incapable of speech. Dropping limply into a chair, he gazed at us for a while in silent terror; then he fell back uttering a wild shriek of laughter.

Mr. Brodribb looked at him in amazement. "What is it, Calverley?" he asked again.

As no answer was forthcoming, he stepped across to the open door of the closet and entered, peering curiously before him. Then he, too, uttered a startled exclamation, and backed out hurriedly, looking pale and flurried.

"Bless my soul!" he ejaculated. "Is the place bewitched?"

He sat down heavily and stared at Calverley, who was still shaking with hysteric laughter; while I, now consumed with curiosity, walked over to the closet to discover the cause of their singular behaviour. As I flung open the door, which the lawyer had closed, I must confess to being very considerably startled; for though the reflection of the open door was plain enough in the mirror, my own reflection was replaced by that of a Chinaman. After a momentary pause of astonishment, I entered the closet and walked towards the mirror; and simultaneously the figure of the Chinaman entered and walked towards me. I had advanced more than halfway down the closet when suddenly the mirror darkened; there was a whirling flash, the Chinaman vanished in an instant, and, as I reached the glass, my own reflection faced me.

I turned back into the room pretty completely enlightened, and looked at Calverley with a new-born distaste. He still sat facing the bewildered lawyer, one moment sobbing convulsively, the next yelping with hysteric laughter. He was not an agreeable spectacle, and when, a few moments later, Thorndyke entered the room, and halted by the door with a stare of disgust, I was moved to join him. But at this juncture a man pushed past Thorndyke, and, striding up to Calverley, shook him roughly by the arm.

"Stop that row!" he exclaimed furiously. "Do you hear? Stop it!"

"I can't help it, Raggerton," gasped Calverley. "He gave me such a turn—the mandarin, you know."

"What!" ejaculated Raggerton.

He dashed across to the closet, looked in, and turned upon Calverley with a snarl. Then he walked out of the room.

"Brodribb," said Thorndyke, "I should like to have a word with you and Jervis outside." Then, as we followed him out on to the landing, he continued: "I have something rather interesting to show you. It is in here."

He softly opened an adjoining door, and we looked into a small unfurnished room. A projecting closet occupied one side of it, and at the door of the closet stood Captain Raggerton, with his hand upon the key. He turned upon us fiercely, though with a look of alarm, and demanded:

"What is the meaning of this intrusion? and who the deuce are you? Do you know that this is my private room?"

"I suspected that it was," Thorndyke replied quietly. "Those will be your properties in the closet, then?"

Raggerton turned pale, but continued to bluster. "Do I understand that you have dared to break into my private closet?" he demanded.

"I have inspected it," replied Thorndyke, "and I may remark that it is useless to wrench at that key, because I have hampered the lock."

"The devil you have!" shouted Raggerton.

"Yes; you see, I am expecting a police-officer with a search warrant, so I wished to keep everything intact."

Raggerton turned livid with mingled fear and rage. He stalked up to Thorndyke with a threatening air, but, suddenly altering his mind, exclaimed, "I must see to this!" and flung out of the room.

Thorndyke took a key from his pocket, and, having locked the door, turned to the closet. Having taken out the key to unhamper the lock with a stout wire, he reinserted it and unlocked the door. As we entered, we found ourselves in a narrow closet, similar to the one in the other room, but darker, owing to the absence of a mirror. A few clothes hung from the pegs, and when Thorndyke had lit a candle that stood on a shelf, we could see more of the details.

"Here are some of the properties," said Thorndyke. He pointed to a peg from which hung a long, blue silk gown of Chinese make, a mandarin's cap, with a pigtail attached to it, and a beautifully-made papier-mache mask. "Observe," said Thorndyke, taking the latter down and exhibiting a label on the inside, marked "Renouard a Paris," "no trouble has been spared."

He took off his coat, slipped on the gown, the mask, and the cap, and was, in a moment, in that dim light, transformed into the perfect semblance of a Chinaman.

"By taking a little more time," he remarked, pointing to a pair of Chinese shoes and a large paper lantern, "the make-up could be rendered more complete; but this seems to have answered for our friend Alfred."

"But," said Mr. Brodribb, as Thorndyke shed the disguise, "still, I don't understand—"

"I will make it clear to you in a moment," said Thorndyke. He walked to the end of the closet, and, tapping the right-hand wall, said: "This is the back of the mirror. You see that it is hung on massive well-oiled hinges, and is supported on this large, rubber-tyred castor, which evidently has ball bearings. You observe three black cords running along the wall, and passing through those pulleys above. Now, when I pull this cord, notice what happens."

He pulled one cord firmly, and immediately the mirror swung noiselessly inwards on its great castor, until it stood diagonally across the closet, where it was stopped by a rubber buffer.

"Bless my soul!" exclaimed Mr. Brodribb. "What an extraordinary thing!"

The effect was certainly very strange, for, the mirror being now exactly diagonal to the two closets they appeared to be a single, continuous passage, with a door at either end. On going up to the mirror, we found that the opening which it had occupied was filled by a sheet of plain glass, evidently placed there as a precaution to prevent any person from walking through from one closet into the other, and so discovering the trick.

"It's all very puzzling," said Mr. Brodribb; "I don't clearly understand it now."

"Let us finish here," replied Thorndyke, "and then I will explain. Notice this black curtain. When I pull the second cord, it slides across the closet and cuts off the light. The mirror now reflects nothing into the other closet; it simply appears dark. And now I pull the third cord."

He did so, and the mirror swung noiselessly back into its place.

"There is only one other thing to observe before we go out," said Thorndyke, "and that is this other mirror standing with its face to the wall. This, of course, is the one that Fred Calverley originally saw at the end of the closet; it has since been removed, and the larger swinging glass put in its place. And now," he continued, when we came out into the room, "let me explain the mechanism in detail. It was obvious to me, when I heard poor Fred Calverley's story, that the mirror was 'faked,' and I drew a diagram of the probable arrangement, which turns out to be correct. Here it is." He took a sheet of paper from his pocket and handed it to the lawyer. "There are two sketches. Sketch 1 shows the mirror in its ordinary position, closing the end of the closet. A person standing at A, of course, sees his reflection facing him at, apparently, A 1. Sketch 2 shows the mirror swung across. Now a person standing at A does not see his own reflection at all; but if some other person is standing in the other closet at B, A sees the reflection of B apparently at B 1—that is, in the identical position that his own reflection occupied when the mirror was straight across."

"I see now," said Brodribb; "but who set up this apparatus, and why was it done?"

"Let me ask you a question," said Thorndyke. "Is Alfred Calverley the next-of-kin?"

"No; there is Fred's younger brother. But I may say that Fred has made a will quite recently very much in Alfred's favour."

"There is the explanation, then," said Thorndyke. "These two scoundrels have conspired to drive the poor fellow to suicide, and Raggerton was clearly the leading spirit. He was evidently concocting some story with which to work on poor Fred's superstitions when the mention of the Chinaman on the steamer gave him his cue. He then invented the very picturesque story of the murdered mandarin and the stolen pearl. You remember that these 'visitations' did not begin until after that story had been told, and Fred had been absent from the house on a visit. Evidently, during his absence, Raggerton took down the original mirror, and substituted this swinging arrangement; and at the same time procured the Chinaman's dress and mask from the theatrical property dealers. No doubt he reckoned on being able quietly to remove the swinging glass and other properties and replace the original mirror before the inquest."

"By God!" exclaimed Mr. Brodribb, "it's the most infamous, cowardly plot I have ever heard of. They shall go to gaol for it, the villains, as sure as I am alive."

But in this Mr. Brodribb was mistaken; for immediately on finding themselves detected, the two conspirators had left the house, and by nightfall were safely across the Channel; and the only satisfaction that the lawyer obtained was the setting aside of the will on facts disclosed at the inquest.

As to Thorndyke, he has never to this day forgiven himself for having allowed Fred Calverley to go home to his death.



VII

THE ALUMINIUM DAGGER

The "urgent call"—the instant, peremptory summons to professional duty—is an experience that appertains to the medical rather than the legal practitioner, and I had supposed, when I abandoned the clinical side of my profession in favour of the forensic, that henceforth I should know it no more; that the interrupted meal, the broken leisure, and the jangle of the night-bell, were things of the past; but in practice it was otherwise. The medical jurist is, so to speak, on the borderland of the two professions, and exposed to the vicissitudes of each calling, and so it happened from time to time that the professional services of my colleague or myself were demanded at a moment's notice. And thus it was in the case that I am about to relate.

The sacred rite of the "tub" had been duly performed, and the freshly-dried person of the present narrator was about to be insinuated into the first instalment of clothing, when a hurried step was heard upon the stair, and the voice of our laboratory assistant, Polton, arose at my colleague's door.

"There's a gentleman downstairs, sir, who says he must see you instantly on most urgent business. He seems to be in a rare twitter, sir—"

Polton was proceeding to descriptive particulars, when a second and more hurried step became audible, and a strange voice addressed Thorndyke.

"I have come to beg your immediate assistance, sir; a most dreadful thing has happened. A horrible murder has been committed. Can you come with me now?"

"I will be with you almost immediately," said Thorndyke. "Is the victim quite dead?"

"Quite. Cold and stiff. The police think—"

"Do the police know that you have come for me?" interrupted Thorndyke.

"Yes. Nothing is to be done until you arrive."

"Very well. I will be ready in a few minutes."

"And if you would wait downstairs, sir," Polton added persuasively, "I could help the doctor to get ready."

With this crafty appeal, he lured the intruder back to the sitting-room, and shortly after stole softly up the stairs with a small breakfast tray, the contents of which he deposited firmly in our respective rooms, with a few timely words on the folly of "undertaking murders on an empty stomach." Thorndyke and I had meanwhile clothed ourselves with a celerity known only to medical practitioners and quick-change artists, and in a few minutes descended the stairs together, calling in at the laboratory for a few appliances that Thorndyke usually took with him on a visit of investigation.

As we entered the sitting-room, our visitor, who was feverishly pacing up and down, seized his hat with a gasp of relief. "You are ready to come?" he asked. "My carriage is at the door;" and, without waiting for an answer, he hurried out, and rapidly preceded us down the stairs.

The carriage was a roomy brougham, which fortunately accommodated the three of us, and as soon as we had entered and shut the door, the coachman whipped up his horse and drove off at a smart trot.

"I had better give you some account of the circumstances, as we go," said our agitated friend. "In the first place, my name is Curtis, Henry Curtis; here is my card. Ah! and here is another card, which I should have given you before. My solicitor, Mr. Marchmont, was with me when I made this dreadful discovery, and he sent me to you. He remained in the rooms to see that nothing is disturbed until you arrive."

"That was wise of him," said Thorndyke. "But now tell us exactly what has occurred."

"I will," said Mr. Curtis. "The murdered man was my brother-in-law, Alfred Hartridge, and I am sorry to say he was—well, he was a bad man. It grieves me to speak of him thus—de mortuis, you know—but, still, we must deal with the facts, even though they be painful."

"Undoubtedly," agreed Thorndyke.

"I have had a great deal of very unpleasant correspondence with him—Marchmont will tell you about that—and yesterday I left a note for him, asking for an interview, to settle the business, naming eight o'clock this morning as the hour, because I had to leave town before noon. He replied, in a very singular letter, that he would see me at that hour, and Mr. Marchmont very kindly consented to accompany me. Accordingly, we went to his chambers together this morning, arriving punctually at eight o'clock. We rang the bell several times, and knocked loudly at the door, but as there was no response, we went down and spoke to the hall-porter. This man, it seems, had already noticed, from the courtyard, that the electric lights were full on in Mr. Hartridge's sitting-room, as they had been all night, according to the statement of the night-porter; so now, suspecting that something was wrong, he came up with us, and rang the bell and battered at the door. Then, as there was still no sign of life within, he inserted his duplicate key and tried to open the door—unsuccessfully, however, as it proved to be bolted on the inside. Thereupon the porter fetched a constable, and, after a consultation, we decided that we were justified in breaking open the door; the porter produced a crowbar, and by our unified efforts the door was eventually burst open. We entered, and—my God! Dr. Thorndyke, what a terrible sight it was that met our eyes! My brother-in-law was lying dead on the floor of the sitting-room. He had been stabbed—stabbed to death; and the dagger had not even been withdrawn. It was still sticking out of his back."

He mopped his face with his handkerchief, and was about to continue his account of the catastrophe when the carriage entered a quiet side-street between Westminster and Victoria, and drew up before a block of tall, new, red-brick buildings. A flurried hall-porter ran out to open the door, and we alighted opposite the main entrance.

"My brother-in-law's chambers are on the second-floor," said Mr. Curtis. "We can go up in the lift."

The porter had hurried before us, and already stood with his hand upon the rope. We entered the lift, and in a few seconds were discharged on to the second floor, the porter, with furtive curiosity, following us down the corridor. At the end of the passage was a half-open door, considerably battered and bruised. Above the door, painted in white lettering, was the inscription, "Mr. Hartridge"; and through the doorway protruded the rather foxy countenance of Inspector Badger.

"I am glad you have come, sir," said he, as he recognized my colleague. "Mr. Marchmont is sitting inside like a watch-dog, and he growls if any of us even walks across the room."

The words formed a complaint, but there was a certain geniality in the speaker's manner which made me suspect that Inspector Badger was already navigating his craft on a lee shore.

We entered a small lobby or hall, and from thence passed into the sitting-room, where we found Mr. Marchmont keeping his vigil, in company with a constable and a uniformed inspector. The three rose softly as we entered, and greeted us in a whisper; and then, with one accord, we all looked towards the other end of the room, and so remained for a time without speaking.

There was, in the entire aspect of the room, something very grim and dreadful. An atmosphere of tragic mystery enveloped the most commonplace objects; and sinister suggestions lurked in the most familiar appearances. Especially impressive was the air of suspense—of ordinary, every-day life suddenly arrested—cut short in the twinkling of an eye. The electric lamps, still burning dim and red, though the summer sunshine streamed in through the windows; the half-emptied tumbler and open book by the empty chair, had each its whispered message of swift and sudden disaster, as had the hushed voices and stealthy movements of the waiting men, and, above all, an awesome shape that was but a few hours since a living man, and that now sprawled, prone and motionless, on the floor.

"This is a mysterious affair," observed Inspector Badger, breaking the silence at length, "though it is clear enough up to a certain point. The body tells its own story."

We stepped across and looked down at the corpse. It was that of a somewhat elderly man, and lay, on an open space of floor before the fireplace, face downwards, with the arms extended. The slender hilt of a dagger projected from the back below the left shoulder, and, with the exception of a trace of blood upon the lips, this was the only indication of the mode of death. A little way from the body a clock-key lay on the carpet, and, glancing up at the clock on the mantelpiece, I perceived that the glass front was open.

"You see," pursued the inspector, noting my glance, "he was standing in front of the fireplace, winding the clock. Then the murderer stole up behind him—the noise of the turning key must have covered his movements—and stabbed him. And you see, from the position of the dagger on the left side of the back, that the murderer must have been left-handed. That is all clear enough. What is not clear is how he got in, and how he got out again."

"The body has not been moved, I suppose," said Thorndyke.

"No. We sent for Dr. Egerton, the police-surgeon, and he certified that the man was dead. He will be back presently to see you and arrange about the post-mortem."

"Then," said Thorndyke, "we will not disturb the body till he comes, except to take the temperature and dust the dagger-hilt."

He took from his bag a long, registering chemical thermometer and an insufflator or powder-blower. The former he introduced under the dead man's clothing against the abdomen, and with the latter blew a stream of fine yellow powder on to the black leather handle of the dagger. Inspector Badger stooped eagerly to examine the handle, as Thorndyke blew away the powder that had settled evenly on the surface.

"No finger-prints," said he, in a disappointed tone. "He must have worn gloves. But that inscription gives a pretty broad hint."

He pointed, as he spoke, to the metal guard of the dagger, on which was engraved, in clumsy lettering, the single word, "TRADITORE."

"That's the Italian for 'traitor,'" continued the inspector, "and I got some information from the porter that fits in with that suggestion. We'll have him in presently, and you shall hear."

"Meanwhile," said Thorndyke, "as the position of the body may be of importance in the inquiry, I will take one or two photographs and make a rough plan to scale. Nothing has been moved, you say? Who opened the windows?"

"They were open when we came in," said Mr. Marchmont. "Last night was very hot, you remember. Nothing whatever has been moved."

Thorndyke produced from his bag a small folding camera, a telescopic tripod, a surveyor's measuring-tape, a boxwood scale, and a sketch-block. He set up the camera in a corner, and exposed a plate, taking a general view of the room, and including the corpse. Then he moved to the door and made a second exposure.

"Will you stand in front of the clock, Jervis," he said, "and raise your hand as if winding it? Thanks; keep like that while I expose a plate."

I remained thus, in the position that the dead man was assumed to have occupied at the moment of the murder, while the plate was exposed, and then, before I moved, Thorndyke marked the position of my feet with a blackboard chalk. He next set up the tripod over the chalk marks, and took two photographs from that position, and finally photographed the body itself.

The photographic operations being concluded, he next proceeded, with remarkable skill and rapidity, to lay out on the sketch-block a ground-plan of the room, showing the exact position of the various objects, on a scale of a quarter of an inch to the foot—a process that the inspector was inclined to view with some impatience.

"You don't spare trouble, Doctor," he remarked; "nor time either," he added, with a significant glance at his watch.

"No," answered Thorndyke, as he detached the finished sketch from the block; "I try to collect all the facts that may bear on a case. They may prove worthless, or they may turn out of vital importance; one never knows beforehand, so I collect them all. But here, I think, is Dr. Egerton."

The police-surgeon greeted Thorndyke with respectful cordiality, and we proceeded at once to the examination of the body. Drawing out the thermometer, my colleague noted the reading, and passed the instrument to Dr. Egerton.

"Dead about ten hours," remarked the latter, after a glance at it. "This was a very determined and mysterious murder."

"Very," said Thorndyke. "Feel that dagger, Jervis."

I touched the hilt, and felt the characteristic grating of bone.

"It is through the edge of a rib!" I exclaimed.

"Yes; it must have been used with extraordinary force. And you notice that the clothing is screwed up slightly, as if the blade had been rotated as it was driven in. That is a very peculiar feature, especially when taken together with the violence of the blow."

"It is singular, certainly," said Dr. Egerton, "though I don't know that it helps us much. Shall we withdraw the dagger before moving the body?"

"Certainly," replied Thorndyke, "or the movement may produce fresh injuries. But wait." He took a piece of string from his pocket, and, having drawn the dagger out a couple of inches, stretched the string in a line parallel to the flat of the blade. Then, giving me the ends to hold, he drew the weapon out completely. As the blade emerged, the twist in the clothing disappeared. "Observe," said he, "that the string gives the direction of the wound, and that the cut in the clothing no longer coincides with it. There is quite a considerable angle, which is the measure of the rotation of the blade."

"Yes, it is odd," said Dr. Egerton, "though, as I said, I doubt that it helps us."

"At present," Thorndyke rejoined dryly, "we are noting the facts."

"Quite so," agreed the other, reddening slightly; "and perhaps we had better move the body to the bedroom, and make a preliminary inspection of the wound."

We carried the corpse into the bedroom, and, having examined the wound without eliciting anything new, covered the remains with a sheet, and returned to the sitting-room.

"Well, gentlemen," said the inspector, "you have examined the body and the wound, and you have measured the floor and the furniture, and taken photographs, and made a plan, but we don't seem much more forward. Here's a man murdered in his rooms. There is only one entrance to the flat, and that was bolted on the inside at the time of the murder. The windows are some forty feet from the ground; there is no rain-pipe near any of them; they are set flush in the wall, and there isn't a foothold for a fly on any part of that wall. The grates are modern, and there isn't room for a good-sized cat to crawl up any of the chimneys. Now, the question is, How did the murderer get in, and how did he get out again?"

"Still," said Mr. Marchmont, "the fact is that he did get in, and that he is not here now; and therefore he must have got out; and therefore it must have been possible for him to get out. And, further, it must be possible to discover how he got out."

The inspector smiled sourly, but made no reply.

"The circumstances," said Thorndyke, "appear to have been these: The deceased seems to have been alone; there is no trace of a second occupant of the room, and only one half-emptied tumbler on the table. He was sitting reading when apparently he noticed that the clock had stopped—at ten minutes to twelve; he laid his book, face downwards, on the table, and rose to wind the clock, and as he was winding it he met his death."

"By a stab dealt by a left-handed man, who crept up behind him on tiptoe," added the inspector.

Thorndyke nodded. "That would seem to be so," he said. "But now let us call in the porter, and hear what he has to tell us."

The custodian was not difficult to find, being, in fact, engaged at that moment in a survey of the premises through the slit of the letter-box.

"Do you know what persons visited these rooms last night?" Thorndyke asked him, when he entered looking somewhat sheepish.

"A good many were in and out of the building," was the answer, "but I can't say if any of them came to this flat. I saw Miss Curtis pass in about nine."

"My daughter!" exclaimed Mr. Curtis, with a start. "I didn't know that."

"She left about nine-thirty," the porter added.

"Do you know what she came about?" asked the inspector.

"I can guess," replied Mr. Curtis.

"Then don't say," interrupted Mr. Marchmont. "Answer no questions."

"You're very close, Mr. Marchmont," said the inspector; "we are not suspecting the young lady. We don't ask, for instance, if she is left-handed."

He glanced craftily at Mr. Curtis as he made this remark, and I noticed that our client suddenly turned deathly pale, whereupon the inspector looked away again quickly, as though he had not observed the change.

"Tell us about those Italians again," he said, addressing the porter. "When did the first of them come here?"

"About a week ago," was the reply. "He was a common-looking man—looked like an organ-grinder—and he brought a note to my lodge. It was in a dirty envelope, and was addressed 'Mr. Hartridge, Esq., Brackenhurst Mansions,' in a very bad handwriting. The man gave me the note and asked me to give it to Mr. Hartridge; then he went away, and I took the note up and dropped it into the letter-box."

"What happened next?"

"Why, the very next day an old hag of an Italian woman—one of them fortune-telling swines with a cage of birds on a stand—came and set up just by the main doorway. I soon sent her packing, but, bless you! she was back again in ten minutes, birds and all. I sent her off again—I kept on sending her off, and she kept on coming back, until I was reg'lar wore to a thread."

"You seem to have picked up a bit since then," remarked the inspector with a grin and a glance at the sufferer's very pronounced bow-window.

"Perhaps I have," the custodian replied haughtily. "Well, the next day there was a ice-cream man—a reg'lar waster, he was. Stuck outside as if he was froze to the pavement. Kept giving the errand-boys tasters, and when I tried to move him on, he told me not to obstruct his business. Business, indeed! Well, there them boys stuck, one after the other, wiping their tongues round the bottoms of them glasses, until I was fit to bust with aggravation. And he kept me going all day.

"Then, the day after that there was a barrel-organ, with a mangy-looking monkey on it. He was the worst of all. Profane, too, he was. Kept mixing up sacred tunes and comic songs: 'Rock of Ages,' 'Bill Bailey,' 'Cujus Animal,' and 'Over the Garden Wall.' And when I tried to move him on, that little blighter of a monkey made a run at my leg; and then the man grinned and started playing, 'Wait till the Clouds roll by.' I tell you, it was fair sickening."
