1. DISASTER

The Throg task force struck the Terran Survey camp a few minutes after dawn, without warning, and with a deadly precision which argued that the aliens had fully reconnoitered and prepared that attack. Eye-searing lances of energy lashed back and forth across the base with methodical accuracy. And a single cowering witness, flattened on a ledge in the heights above, knew that when the last of those yellow-red bolts fell, nothing human would be left alive down there. His teeth closed hard upon the thick stuff of the sleeve covering his thin forearm, and in his throat a scream of terror and rage was stillborn.

More than caution kept him pinned on that narrow shelf of rock. Watching that holocaust below, Shann Lantee could not force himself to move. The sheer ruthlessness of the Throg move-in left him momentarily weak. To listen to a tale of Throgs in action, and to be an eye-witness to such action, were two vastly different things. He shivered in spite of the warmth of the Survey Corps uniform.

As yet he had sighted none of the aliens, only their plate-shaped flyers. They would stay aloft until their long-range weapon cleared out all opposition. But how had they been able to make such a complete annihilation of the Terran force? The last report had placed the nearest Throg nest at least two systems away from Warlock. And a patrol lane had been drawn about the Circe system the minute that Survey had marked its second planet ready for colonization. Somehow the beetles had slipped through that supposedly tight cordon and would now consolidate their gains with their usual speed at rooting. First an energy attack to finish the small Terran force; then they would simply take over.

A month later, or maybe two months, and they could not have done it. The grids would have been up, and any Throg ship venturing into Warlock's amber-tinted sky would abruptly cease to be. In the race for survival as a galactic power, Terra had that one small edge over the swarms of the enemy. They need only stake out their new-found world and get the grids assembled on its surface; then that planet would be locked to the beetles. The critical period was between the first discovery of a suitable colony world and the erection of grid control. Planets in the past had been lost during that time lag, just as Warlock was lost now.

Throgs and Terrans ... For more than a century now, planet time, they had been fighting their queer, twisted war among the stars. Terrans hunted worlds for colonization, the old hunger for land of their own driving men from the over-populated worlds, out of Sol's system to the far stars. And those worlds barren of intelligent native life, open to settlers, were none too many and widely scattered. Perhaps half a dozen were found in a quarter century, and of that six maybe only one was suitable for human life without any costly and lengthy adaption of man or world. Warlock was one of the lucky finds which came so seldom.

Throgs were predators, living on the loot they garnered. As yet, mankind had not been able to discover whether they did indeed swarm from any home world. Perhaps they lived eternally on board their plate ships with no permanent base, forced into a wandering life by the destruction of the planet on which they had originally been spawned. But they were raiders now, laying waste defenseless worlds, picking up the wealth of shattered cities in which no native life remained. And their hidden temporary bases were looped about the galaxy, their need for worlds with an atmosphere similar to Terra's as necessary as that of man. For in spite of their grotesque insectile bodies, their wholly alien minds, the Throgs were warm-blooded, oxygen-breathing creatures.

After the first few clashes the early Terran explorers had endeavored to promote a truce between the species, only to discover that between Throg and man there appeared to be no meeting ground at all—total differences of mental processes producing insurmountable misunderstanding. There was simply no point of communication. So the Terrans had suffered one smarting defeat after another until they perfected the grid. And now their colonies were safe, at least when time worked in their favor.

It had not on Warlock.

A last vivid lash of red cracked over the huddle of domes in the valley. Shann blinked, half blinded by that glare. His jaws ached as he unclenched his teeth. That was the finish. Breathing raggedly, he raised his head, beginning to realize that he was the only one of his kind left alive on a none-too-hospitable world controlled by enemies—without shelter or supplies.

He edged back into the narrow cleft which was the entrance to the ledge. As a representative of his species he was not impressive, and now with those shudders he could not master, shaking his thin body, he looked even smaller and more vulnerable. Shann drew his knees up close under his chin. The hood of his woodsman's jacket was pushed back in spite of the chill of the morning, and he wiped the back of his hand across his lips and chin in an oddly childish gesture.

None of the men below who had been alive only minutes earlier had been close friends of his; Shann had never known anyone but acquaintances in his short, roving life. Most people had ignored him completely except to give orders, and one or two had been actively malicious—like Garth Thorvald. Shann grimaced at a certain recent memory, and then that grimace faded into wonder. If young Thorvald hadn't purposefully tried to get Shann into trouble by opening the wolverines' cage, Shann wouldn't be here now—alive and safe for a time—he'd have been down there with the others.

The wolverines! For the first time since Shann had heard the crackle of the Throg attack he remembered the reason he had been heading into the hills. Of all the men on the Survey team, Shann Lantee had been the least important. The dirty, tedious clean-up jobs, the dull routines which required no technical training but which had to be performed to keep the camp functioning comfortably, those had been his portion. And he had accepted that status willingly, just to have a chance to be included among Survey personnel. Not that he had the slightest hope of climbing up to even an S-E-Three rating in the service.

Part of those menial activities had been to clean the animal cages. And there Shann Lantee had found something new, something so absorbing that most of the tiring dull labor had ceased to exist except as tasks to finish before he could return to the fascination of the animal runs.

Survey teams had early discovered the advantage of using mutated and highly trained Terran animals as assistants in the exploration of strange worlds. From the biological laboratories and breeding farms on Terra came a trickle of specialized aides-de-camp to accompany man into space. Some were fighters, silent, more deadly than weapons a man wore at his belt or carried in his hands. Some were keener eyes, keener noses, keener scouts than the human kind could produce. Bred for intelligence, for size, for adaptability to alien conditions, the animal explorers from Terra were prized.

Wolverines, the ancient "devils" of the northlands on Terra, were being tried for the first time on Warlock. Their caution, a quality highly developed in their breed, made them testers for new territory. Able to tackle in battle an animal three times their size, they should be added protection for the man they accompanied into the wilderness, and their wide ranging, their ability to climb and swim, and above all, their curiosity were assets.

Shann had begun contact by cleaning their cages; he ended captivated by these miniature bears with long bushy tails. And to his unbounded delight the attraction was mutual. Alone to Taggi and Togi he was a person, an important person. Those teeth, which could tear flesh into ragged strips, nipped gently at his fingers, closed without any pressure on arm, even on nose and chin in what was the ultimate caress of their kind. Since they were escape artists of no mean ability, twice he had had to track and lead them back to camp from forays of their own devising.

But the second time he had been caught by Fadakar, the chief of animal control, before he could lock up the delinquents. And the memory of the resulting interview still had the power to make him flush with impotent anger. Shann's explanation had been contemptuously brushed aside, and he had been delivered an ultimatum. If his carelessness occurred again, he would be sent back on the next supply ship, to be dismissed without an official sign-off on his work record, thus locked out of even the lowest level of Survey for the rest of his life.

That was why Garth Thorvald's act of the night before had made Shann brave the unknown darkness of Warlock alone when he had discovered that the test animals were gone. He had to locate and return them before Fadakar made his morning inspection; Garth Thorvald's attempt to get him into bad trouble had saved his life.

Shann cowered back, striving to make his huddled body as small as possible. One of the Throg flyers appeared silently out of the misty amber of the morning sky, hovering over the silent camp. The aliens were coming in to inspect the site of their victory. And the safest place for any Terran now was as far from the vicinity of those silent domes as he could get. Shann's slight body was an asset as he wedged through the narrow mouth of a cleft and so back into the cliff wall. The climb before him he knew in part, for this was the path the wolverines had followed on their two other escapes. A few moments of tricky scrambling and he was out in a cuplike depression choked with brush covered with the purplish foliage of Warlock. On the other side of that was a small cut to a sloping hillside, giving on another valley, not as wide as that in which the camp stood, but one well provided with cover in the way of trees and high-growing bushes.

A light wind pushed among the trees, and twice Shann heard the harsh, rasping call of a clak-clak—one of the bat-like leather-winged flyers that laired in pits along the cliff walls. That present snap of two-tone complaint suggested that the land was empty of strangers. For the clak-claks vociferously and loudly resented encroachment on their chosen hunting territory.

Shann hesitated. He was driven by the urge to put as much distance between him and the landing Throg ship as he could. But to arouse the attention of inquisitive clak-claks was asking for trouble. Perhaps it would be best to keep on along the top of the cliff, rather than risk a descent to take cover in the valley the flyers patrolled.

A patch of dust, sheltered by a tooth-shaped projection of rock, gave the Terran his first proof that Taggi and his mate had preceded him, for printed firmly there was the familiar paw mark of a wolverine. Shann began to hope that both animals had taken to cover in the wilderness ahead.

He licked dry lips. Having left secretly without any emergency pack, he had no canteen, and now Shann inventoried his scant possessions—a field kit, heavy-duty clothing, a short hooded jacket with attached mittens, the breast marked with the Survey insignia. His belt supported a sheathed stunner and bush knife, and seam pockets held three credit tokens, a twist of wire intended to reinforce the latch of the wolverine cage, a packet of bravo tablets, two identity and work cards, and a length of cord. No rations—save the bravos—no extra charge for his stunner. But he did have, weighing down a loop on the jacket, a small atomic torch.

The path he followed ended abruptly in a cliff drop, and Shann made a face at the odor rising from below, even though that scent meant he could climb down to the valley floor here without fearing any clak-clak attention. Chemical fumes from a mineral spring funneled against the wall, warding off any nesting in this section.

Shann drew up the hood of his jacket and snapped the transparent face mask into place. He must get away—then find food, water, a hiding place. That will to live which had made Shann Lantee fight innumerable battles in the past was in command, bracing him with a stubborn determination.

The fumes swirled up in a smoke haze about his waist, but he strode on, heading for the open valley and cleaner air. That sickly lavender vegetation bordering the spring deepened in color to the normal purple-green, and then he was in a grove of trees, their branches pointed skyward at sharp angles to the rust-red trunks.

A small skitterer burst from moss-spotted ground covering, giving an alarmed squeak, skimming out of sight as suddenly as it had appeared. Shann squeezed between two trees and then paused. The trunk of the larger was deeply scored with scratches dripping viscid gobs of sap, a sap which was a bright froth of scarlet. Taggi had left his mark here, and not too long ago.

The soft carpet of moss showed no paw marks, but he thought he knew the goal of the animals—a lake down-valley. Shann was beginning to plan now. The Throgs had not blasted the Terran camp out of existence; they had only made sure of the death of its occupiers. Which meant they must have some use for the installations. For the general loot of a Survey field camp would be relatively worthless to those who picked over the treasure of entire cities elsewhere. Why? What did the Throgs want? And would the alien invaders continue to occupy the domes for long?

Shann did not realize what had happened to him since that shock of ruthless attack. From early childhood, when he had been thrown on his own to scratch a living—a borderline existence of a living—on the Dumps of Tyr, he had had to use his wits to keep life in a scrawny and undersized body. However, since he had been eating regularly from Survey rations, he was not quite so scrawny any more.

His formal education was close to zero, his informal and off-center schooling vast. And that particular toughening process which had been working on him for years now aided in his speedy adaption to a new set of facts, formidable ones. He was alone on a strange and perhaps hostile world. Water, food, safe shelter, those were important now. And once again, away from the ordered round of the camp where he had been ruled by the desires and requirements of others, he was thinking, planning in freedom. Later (his hand went to the butt of his stunner) perhaps later he might just find a way of extracting an accounting from the beetle-faces, too.

For the present, he would have to keep away from the Throgs, which meant well away from the camp. A fleck of green showed through the amethyst foliage before him—the lake! Shann wriggled through a last bush barrier and stood to look out over that surface. A sleek brown head bobbed up. Shann put fingers to his mouth and whistled. The head turned, black button eyes regarded him, short legs began to churn water. To his gratification the swimmer was obeying his summons.

Taggi came ashore, pausing on the fine gray sand of the verge to shake himself vigorously. Then the wolverine came upslope at a clumsy gallop to Shann. With an unknown feeling swelling inside him, the Terran went down on both knees, burying both hands in the coarse brown fur, warming to the uproarious welcome Taggi gave him.

"Togi?" Shann asked as if the other could answer. He gazed back to the lake, but Taggi's mate was nowhere in sight.

The blunt head under his hand swung around, black button nose pointed north. Shann had never been sure just how intelligent, as mankind measured intelligence, the wolverines were. He had come to suspect that Fadakar and the other experts had underrated them and that both beasts understood more than they were given credit for. Now he followed an experiment of his own, one he had had a chance to try only a few times before and never at length. Pressing his palm flat on Taggi's head, Shann thought of Throgs and of their attack, trying to arouse in the animal a corresponding reaction to his own horror and anger.

And Taggi responded. A mutter became a growl, teeth gleamed—those cruel teeth of a carnivore to whom they were weapons of aggression. Danger ... Shann thought "danger." Then he raised his hand, and the wolverine shuffled off, heading north. The man followed.

They discovered Togi busy in a small cove where a jagged tangle of drift made a mat dating from the last high-water period. She was finishing a hearty breakfast, the remains of a water rat being buried thriftily against future need after the instincts of her kind. When she was done she came to Shann, inquiry plain to read in her eyes.

There was water here, and good hunting. But the site was too close to the Throgs. Let one of their exploring flyers sight them, and the little group was finished. Better cover, that's what the three fugitives must have. Shann scowled, not at Togi, but at the landscape. He was tired and hungry, but he must keep on going.

A stream fed into the cove from the west, a guide of sorts. With very little knowledge of the countryside, Shann was inclined to follow that.

Overhead the sun made its usual golden haze of the sky. A flight of vivid green streaks marked a flock of lake ducks coming for a morning feeding. Lake duck was good eating, but Shann had no time to hunt one now. Togi started down the bank of the stream, Taggi behind her. Either they had caught his choice subtly through some undefined mental contact, or they had already picked that road on their own.

Shann's attention was caught by a piece of the drift. He twisted the length free and had his first weapon of his own manufacture, a club. Using it to hold back a low sweeping branch, he followed the wolverines.

Within the half hour he had breakfast, too. A pair of limp skitterers, their long hind feet lashed together with a thong of grass, hung from his belt. They were not particularly good eating, but they were meat and acceptable.

The three, man and wolverines, made their way up the stream to the valley wall and through a feeder ravine into the larger space beyond. There, where the stream was born at the foot of a falls, they made their first camp. Judging that the morning haze would veil any smoke, Shann built a pocket-size fire. He seared rather than roasted the skitterers after he had made an awkward and messy business of skinning them, and tore the meat from the delicate bones in greedy mouthfuls. The wolverines lay side by side on the gravel, now and again raising a head alertly to test the scent on the air, or gaze into the distance.

Taggi made a warning sound deep in the throat. Shann tossed handfuls of sand over the dying fire. He had only time to fling himself face-down, hoping the drab and weathered cloth of his uniform faded into the color of the earth on which he lay, every muscle tense.

A shadow swung across the hillside. Shann's shoulders hunched, and he cowered again. That terror he had known on the ledge was back in full force as he waited for the beam to lick at him as it had earlier at his fellows. The Throgs were on the hunt....



2. DEATH OF A SHIP

That sigh of displaced air was not as loud as a breeze, but it echoed monstrously in Shann's ears. He could not believe in his luck as that sound grew fainter, drew away into the valley he had just left. With infinite caution he raised his head from his arm, still hardly able to accept the fact that he had not been sighted, that the Throgs and their flyer were gone.

But that black plate was spinning out into the sun haze. One of the beetles might have suspected that there were Terran fugitives and ordered a routine patrol. After all, how could the aliens know that they had caught all but one of the Survey party in camp? Though with all the Terran scout flitters grounded on the field, the men dead in their bunks, the surprise would seem to be complete.

As Shann moved, Taggi and Togi came to life also. They had gone to earth with speed, and the man was sure that both beasts had sensed danger. Not for the first time he knew a burning desire for the formal education he had never had. In camp he had listened, dragging out routine jobs in order to overhear reports and the small talk of specialists keen on their own particular hobbies. But so much of the information Shann had thus picked up to store in a retentive memory he had not understood and could not fit together. It had been as if he were trying to solve some highly important puzzle with at least a quarter of the necessary pieces missing, or with unrelated bits from others intermixed. How much control did a trained animal scout have over his furred or feathered assistants? And was part of that mastery a mental rapport built up between man and animal?

How well would the wolverines obey him now, especially when they would not return to camp where cages stood waiting as symbols of human authority? Wouldn't a trek into the wilderness bring about a revolt for complete freedom? If Shann could depend upon the animals, it would mean a great deal. Not only would their superior hunting ability provide all three with food, but their scouting senses, so much keener than his, might erect a slender wall between life and death.

Few large native beasts had been discovered on Warlock by the Terran explorers. And of those four or five different species, none had proved hostile if unprovoked. But that did not mean that somewhere back in the wild lands into which Shann was heading there were no heretofore unknowns, perhaps slyer and as vicious as the wolverines when they were aroused to rage.

Then there were the "dreams," which had afforded the prime source of camp discussion and dispute. Shann brushed coarse sand from his boots and thought about the dreams. Did they or did they not exist? You could start an argument any time by making a definite statement for or against the peculiar sort of dreaming reported by the first scout to set ship on this world.

The Circe system, of which Warlock was the second of three planets, had first been scouted four years ago by one of those explorers traveling solo in Survey service. Everyone knew that the First-In Scouts were a weird breed, almost a mutation of Terran stock—their reports were rife with strange observations.

So an alarming one concerning Circe (a yellow sun such as Sol) and her three planets was not so rare. Witch, the world nearest in orbit to Circe, was too hot for human occupancy without drastic and too costly world-changing. Wizard, the third out from the sun, was mostly bare rock and highly poisonous water. But Warlock, swinging through space between two forbidding neighbors, seemed to be just what the settlement board ordered.

Then the Survey scout, even in the cocoon safety of his well-armed ship, began to dream. And from those dreams a horror of the apparently empty world developed, until he fled the planet to preserve his sanity. There had been a second visit to Warlock in check; worlds so well adapted to human emigration could not be lightly thrown away. And this time there was a negative report, no trace of dreams, no registration of any outside influence on the delicate and complicated equipment the ship carried. So the Survey team had been dispatched to prepare for the coming of the first pioneers, and none of them had dreamed either—at least, no more than the ordinary dreams all men accepted.

Only there were those who pointed out that the seasons had changed between the first and second visits to Warlock. That first scout had planeted in summer; his successors had come in fall and winter. They argued that the final release of the world for settlement should not be given until the full year on Warlock had been sampled.

But the pressure of Emigrant Control had forced their hands, that and the fear of just what had eventually happened—an attack from the Throgs. So they had speeded up the process of declaring Warlock open. Only Ragnar Thorvald had protested that decision up to the last and had gone back to headquarters on the supply ship a month ago to make a last appeal for a more careful study.

Shann stopped brushing the sand from the tough fabric above his knee. Ragnar Thorvald ... He remembered back to the port landing apron on another world, remembered with a sense of loss he could not define. That had been about the second biggest day of his short life; the biggest had come earlier when they had actually allowed him to sign on for Survey duty.

He had tumbled off the cross-continent cargo carrier, his kit—a very meager kit—slung over his thin shoulder, a hot eagerness expanding inside him until he thought that he could not continue to throttle down that wild happiness. There was a waiting starship. And he—Shann Lantee from the Dumps of Tyr, without any influence or schooling—was going to blast off in her, wearing the brown-green uniform of Survey!

Then he had hesitated uncertainly, had not quite dared cross the few feet of apron lying between him and that compact group wearing the same uniform—with a slight difference, that of service bars and completion badges and rank insignia—with the unconscious self-assurance of men who had done this many times before.

But after a moment that whole group had become in his own shy appraisal just a background for one man. Shann had never before known in his pinched and limited childhood, his lost boyhood, anyone who aroused in him hero worship. And he could not have put a name to the new emotion that added so suddenly to his burning desire to make good, not only to hold the small niche in Survey which he had already so painfully achieved, but to climb, until he could stand so in such a group talking easily to that tall man, his uncovered head bronze-yellow in the sunlight, his cool gray eyes pale in his brown face.

Not that any of those wild dreams born in that minute or two had been realized in the ensuing months. Probably those dreams had always been as wild as the ones reported by the first scout on Warlock. Shann grinned wryly now at the short period of childish hope and half-confidence that he could do big things. Only one Thorvald had ever noticed Shann's existence in the Survey camp, and that had been Garth.

Garth Thorvald, a far less impressive—one could say "smudged"—copy of his brother. Swaggering with an arrogance Ragnar never showed, Garth was a cadet on his first mission, intent upon making Shann realize the unbridgeable gulf between a labor hand and an officer-to-be. He had appeared to know right from their first meeting just how to make Shann's life a misery.

Now, in this slit of valley well away from the domes, Shann's fists balled. He pounded them against the earth in a way he had so often hoped to plant them on Garth's smoothly handsome face, his well-muscled body. One didn't survive the Dumps of Tyr without learning how to use fists, and boots, and a list of tricks they didn't teach in any academy. He had always been sure that he could take Garth if they mixed it up. But if he had loosed the tight rein he had kept on his temper and offered that challenge, he would have lost his chance with Survey. Garth had proved himself able to talk his way out of any scrape, even minor derelictions of duty, and he far out-ranked Shann. The laborer from Tyr had had to swallow all that the other could dish out and hope that on his next assignment he would not be a member of young Thorvald's team. Though, because of Garth Thorvald, Shann's toll of black record marks had mounted dangerously high and each day the chance for any more duty tours had grown dimmer.

Shann laughed, and the sound was ugly. That was one thing he didn't have to worry about any longer. There would be no other assignments for him, the Throgs had seen to that. And Garth ... well, there would never be a showdown between them now. He stood up. The Throg ship had disappeared; they could push on.

He found a break in the cliff wall which was climbable, and he coaxed the wolverines after him. When they stood on the heights from which the falls tumbled, Taggi and Togi rubbed against him, cried for his attention. They, too, appeared to need the reassurance they got from contact with him, for they were also fugitives on this alien world, the only representatives of their kind.

Since he did not have any definite goal in view, Shann continued to be guided by the stream, following its wanderings across a plateau. The sun was warm, so he carried his jacket slung across one shoulder. Taggi and Togi ranged ahead, twice catching skitterers, which they devoured voraciously. A shadow on a sun-baked rock sent the Terran skidding for cover until he saw that it was cast by one of the questing falcons from the upper peaks. But that shook his confidence, so he again sought cover, ashamed at his own carelessness.

In the late afternoon he reached the far end of the plateau, faced a climb to peaks which still bore cones of snow, now tinted a soft peach by the sun. Shann studied that possible path and distrusted his own powers to take it without proper equipment or supplies. He must turn either north or south, though he would then have to abandon a sure water supply in the stream. Tonight he would camp where he was. He had not realized how tired he was until he found a likely half-cave in the mountain wall and crawled in. There was too much danger in fire here; he would have to do without that first comfort of his kind.

Luckily, the wolverines squeezed in beside him to fill the hole. With their warm furred bodies sandwiching him, Shann dozed, awoke, and dozed again, listening to night sounds—the screams, cries, hunting calls, of the Warlock wilds. Now and again one of the wolverines whined and moved uneasily.

Fingers of sun picked at Shann through a shaft among the rocks, striking his eyes. He moved, blinked blearily awake, unable for the first few seconds to understand why the smooth plasta wall of his bunk had become rough red stone. Then he remembered. He was alone and he threw himself frantically out of the cave, afraid the wolverines had wandered off. Only both animals were busy clawing under a boulder with a steady persistence which argued there was a purpose behind that effort.

A sharp sting on the back of one hand made that purpose only too clear to Shann, and he retreated hurriedly from the vicinity of the excavation. They had found an earth-wasp's burrow and were hunting grubs, naturally arousing the rightful inhabitants to bitter resentment.

Shann faced the problem of his own breakfast. He had had the immunity shots given to all members of the team, and he had eaten game brought in by exploring parties and labeled "safe." But how long he could keep to the varieties of native food he knew was uncertain. Sooner or later he must experiment for himself. Already he drank the stream water without the aid of purifiers, and so far there had been no ill results from that necessary recklessness. Now the stream suggested fish. But instead he chanced upon another water inhabitant which had crawled up on land for some obscure purpose of its own. It was a sluggish scaled thing, an easy victim to his club, with thin, weak legs it could project at will from a finned and armor-plated body.

Shann offered the head and guts to Togi, who had abandoned the wasp nest. She sniffed in careful investigation and then gulped. Shann built a small fire and seared the firm greenish flesh. The taste was flat, lacking salt, but the food eased his emptiness. Enheartened, he started south, hoping to find water sometime during the morning.

By noon he had his optimism justified with the discovery of a spring, and the wolverines had brought down a slender-legged animal whose coat was close in shade to the dusky purple of the vegetation. Smaller than a Terran deer, its head bore, not horns, but a ridge of stiffened hair rising in a point some twelve inches about the skull dome. Shann haggled off some ragged steaks while the wolverines feasted in earnest, carefully burying the head afterward.

It was when Shann knelt by the spring pool to wash that he caught the clamor of the clak-claks. He had seen or heard nothing of the flyers since he had left the lake valley. But from the noise now rising in an earsplitting volume, he thought there was a sizable colony near-by and that the inhabitants were thoroughly aroused.

He crept on his hands and knees to near-by brush cover, heading toward the source of that outburst. If the claks were announcing a Throg scouting party, he wanted to know it.

Lying flat, with branches forming a screen over him, the Terran gazed out on a stretch of grassland which sloped at a fairly steep angle to the south and which must lead to a portion of countryside well below the level he was now traversing.

The clak-claks were skimming back and forth, shrieking their staccato war cries. Following the erratic dashes of their flight formation, Shann decided that whatever they railed against was on the lower level, out of his sight from that point. Should he simply withdraw, since the disturbance was not near him? Prudence dictated that; yet still he hesitated.

He had no desire to travel north, or to try and scale the mountains. No, south was his best path, and he should be very sure that route was closed before he retreated.

Since any additional fuss the clak-claks might make on sighting him would be undistinguished in their now general clamor, the Terran crawled on to where tall grass provided a screen at the top of the slope. There he stopped short, his hands digging into the earth in sudden braking action.

Below, the ground steamed from a rocket flare-back, grasses burned away from the fins of a small scoutship. But even as Shann rose to one knee, his shout of welcome choked in his throat. One of those fins sank, canting the ship crookedly, preventing any new take-off. And over the crown of a low hill to the west swung the ominous black plate of a Throg flyer.

The Throg ship came up in a burst of speed, and Shann waited tensely for some countermove from the scout. Those small speedy Terran ships were prudently provided with weapons triply deadly in proportion to their size. He was sure that the Terran ship could hold its own against the Throg, even eliminate the enemy. But there was no fire from the slanting pencil of the scout. The Throg circled warily, obviously expecting a trap. Twice it darted back in the direction from which it had come. As it returned from its second retreat, another of its kind showed, a black coin dot against the amber of the sky.

Shann felt sick inside. Now the Terran scout had lost any advantage and perhaps all hope. The Throgs could box the other in, cut the downed ship to pieces with their energy beams. He wanted to crawl away and not witness this last disaster for his kind. But some stubborn core of will kept him where he was.

The Throgs began to circle while beneath them the flock of clak-claks screamed and dived at the slanting nose of the Terran ship. Then that same slashing energy he had watched quarter the camp snapped from the far plate across the stricken scout. The man who had piloted her, if not dead already (which might account for the lack of defense), must have fallen victim to that. But the Throg was going to make very sure. The second flyer halted, remaining poised long enough to unleash a second bolt—dazzling any watching eyes and broadcasting a vibration to make Shann's skin crawl when the last faint ripple reached his lookout post.

What happened then the overconfident Throg was not prepared to take. Shann cried out, burying his face on his arm, as pinwheels of scarlet light blotted out normal sight. There was an explosion, a deafening blast. He cowered, blind, unable to hear. Then, rubbing at his eyes, he tried to see what had happened.

Through watery blurs he made out the Throg ship, not swinging now in serene indifference to Warlock's gravity, but whirling end over end across the sky as might a leaf tossed in a gust of wind. Its rim caught against a rust-red cliff, it rebounded and crumpled. Then it came down, smashing perhaps half a mile away from the smoking crater in which lay the mangled wreckage of the Terran ship. The disabled scout pilot must have played a last desperate game, making of his ship bait for a trap.

The Terran had taken one Throg with him. Shann rubbed again at his eyes, just barely able to catch a glimpse of the second ship flashing away westward. Perhaps it was only his impaired sight, but it appeared to him that the Throg followed an erratic path, either as if the pilot feared to be caught by a second shot, or because that ship had also suffered some injury.

Acid smoke wreathed up from the valley making Shann retch and cough. There could be no survivor from the Terran scout, and he did not believe that any Throg had lived to crawl free of the crumpled plate. But there would be other beetles swarming here soon. They would not dare to leave the scene unsearched. He wondered about that scout. Had the pilot been aiming for the Survey camp, the absence of any rider beam from there warning him off so that he made the detour which brought him here? Or had the Throgs tried to blast the Terran ship in the upper atmosphere, crippling it, making this a forced landing? But at least this battle had cost the Throgs, settling a small portion of the Terran debt for the lost camp.

The length of time between Shann's sighting of the grounded ship and the attack by the Throgs had been so short that he had not really developed any strong hope of rescue to be destroyed by the end of the crippled ship. On the other hand, seeing the Throgs take a beating had exploded his subconscious acceptance of their superiority. He might not have even the resources of a damaged scout at his command. But he did have Taggi, Togi, and his own brain. Since he was fated to permanent exile on Warlock, there might just be some way to make the beetles pay for that.

He licked his lips. Real action against the aliens would take a lot of planning. Shann would have to know more about what made a Throg a Throg, more than all the wild stories he had heard over the years. There had to be some way a Terran could move effectively against a beetle-head. And he had a lot of time, maybe the rest of his life to work out a few answers. That Throg ship lying wrecked at the foot of the cliff ... perhaps he could do a little investigating before any rescue squad arrived. Shann decided such a move was worth the try and whistled to the wolverines.



3. TO CLOSE RANKS

Shann made his way at an angle to avoid the smoking pit cradling the wreckage of the Terran ship. There were no signs of life about the Throg plate as he approached. A quarter of its bulk was telescoped back into the rest, and surely none of the aliens could have survived such a smash, tough as they were reputed to be with those horny carapaces serving them in place of more vulnerable human skin.

He sniffed. There was a nauseous odor heavy on the morning air, one which would make a lasting impression on any human nose. The port door in the black ship stood open, perhaps having burst in the impact against the cliff. Shann had almost reached it when a crackle of chain lightning beat across the ground before him, turning the edge of the buckled entrance panel red.

Shann dropped to the ground, drawing his stunner, knowing at the same moment that such a weapon was about as much use in meeting a blaster as a straw wand would be to ward off a blazing coal. A chill numbness held him as he waited for a second blast to charr the flesh between his shoulders. So there had been a Throg survivor, after all.

But as moments passed and the Throg did not move in to make an easy kill, Shann collected his wits. Only one shot! Was the beetle injured, unable to make sure of even an almost defenseless prey? The Throgs seldom took prisoners. When they did....

The Terran's lips tightened. He worked his hand under his prone body, feeling for the hilt of his knife. With that he could speedily remove himself from the status of Throg prisoner, and he would do it gladly if there was no hope of escape. Had there been only one charge left in that blaster? Shann could make half a dozen guesses as to why the other had made no move, but that shot had come from behind him, and he dared not turn his head or otherwise make an effort to see what the other might be doing.

Was it only his imagination, or had that stench grown stronger during the last few seconds? Could the Throg be creeping up on him? Shann strained his ears, trying to catch some sound he could interpret. The few clak-claks that had survived the blast about the ship were shrieking overhead, and Shann made one attempt at counterattack.

He whistled the wolverines' call. The pair had not been too willing to follow him down into this valley, and they had avoided the crater at a very wide circle. But if they would obey him now, he just might have a chance.

There! That had been a sound, and the smell was stronger. The Throg must be coming to him. Again Shann whistled, holding in his mind his hatred for the beetle-head, the need for finishing off that alien. If the animals could pick either thoughts or emotions out of their human companion, this was the time for him to get those unspoken half-orders across.

Shann slammed his hand hard against the ground, sent his body rolling, his stunner up and ready.

And now he could see that grotesque thing, swaying weakly back and forth on its thin legs, yet holding a blaster, bringing that weapon up to center it on him. The Throg was hunched over and perhaps to Taggi presented the outline of some four-footed creature to be hunted. For the wolverine male sprang for the horn-shelled shoulders.

Under that impact that Throg sagged forward. But Taggi, outraged at the nature of creature he had attacked, squalled and retreated. Shann had had his precious seconds of distraction. He fired, the core of the stun beam striking full into the flat dish of the alien's "face."

That bolt, which would have shocked a mammal into insensibility, only slowed the Throg. Shann rolled again, gaining a temporary cover behind the wrecked ship. He squirmed under metal hot enough to scorch his jacket and saw the reflection of a second blaster shot which had been fired seconds late.

Now the Throg had him tied down. But to get at the Terran the alien would have to show himself, and Shann had one chance in fifty, which was better than that of three minutes ago—when the odds had been set at one in a hundred. He knew that he could not press the wolverines in again. Taggi's distaste was too manifest; Shann had been lucky that the animal had made one abortive attack.

Perhaps the Terran's escape and Taggi's action had made the alien reckless. Shann had no clue to the thinking processes of the non-human, but now the Throg staggered around the end of the plate, his digits, which were closer to claws than fingers, fumbling with his weapon. The Terran snapped another shot from his stunner, hoping to slow the enemy down. But he was trapped. If he turned to climb the cliff at his back, the beetle-head could easily pick him off.

A rock hurtled from the heights above, striking with deadly accuracy on the domed, hairless head of the Throg. His armored body crashed forward, struck against the ship, and rebounded to the ground. Shann darted forward to seize the blaster, kicking loose the claws which still grasped it, before he flattened back to the cliff, the strange weapon over his arm, his heart beating wildly.

That rock had not bounded down the mountainside by chance; it had been hurled with intent and aimed carefully at its target. And no Throg would kill one of his fellows. Or would he? Suppose orders had been issued to take a Terran prisoner and the Throg by the ship had disobeyed? Then, why a rock and not a blaster bolt?

Shann edged along until the upslanted, broken side of the Throg flyer provided him with protection from any overhead attack. Under that shelter he waited for the next move from his unknown rescuer.

The clak-claks wheeled closer to earth. One lit boldly on the carapace of the inert Throg, shuffling ungainly along that horny ridge. Cradling the blaster, the Terran continued to wait. His patience was rewarded when that investigating clak-clak took off uttering an enraged snap or two. He heard what might be the scrape of boots across rock, but that might also have come from horny skin meeting stone.

Then the other must have lost his footing not too far above. Accompanied by a miniature landslide of stones and earth, a figure slid down several yards away. Shann waited in a half-crouch, his looted blaster covering the man now getting to his feet. There was no mistaking the familiar uniform, or even the man. How Ragnar Thorvald had reached that particular spot on Warlock or why, Shann could not know. But that he was there, there was no denying.

Shann hurried forward. It had been when he caught his first sight of Thorvald that he realized just how deep his unacknowledged loneliness had bit. There were two Terrans on Warlock now, and he did not need to know why. But Thorvald was staring back at him with the blankness of non-recognition.

"Who are you?" The demand held something close to suspicion.

That note in the other's voice wiped away a measure of Shann's confidence, threatened something which had flowered in him since he had struck into the wilderness on his own. Three words had reduced him again to Lantee, unskilled laborer.

"Lantee. I'm from the camp...."

Thorvald's eagerness was plain in his next question: "How many of you got away? Where are the rest?" He gazed past Shann up the plateau slope as if he expected to see the personnel of the camp sprout out of the cloak of grass along the verge.

"Just me and the wolverines," Shann answered in a colorless voice. He cradled the blaster on his hip, turned a little away from the officer.

"You ... and the wolverines?" Thorvald was plainly startled. "But ... where? How?"

"The Throgs hit very early yesterday morning. They caught the rest in camp. The wolverines had escaped from their cage, and I was out hunting them...." He told his story baldly.

"You're sure about the rest?" Thorvald had a thin steel of rage edging his voice. Almost, Shann thought, as if he could turn that blade of rage against one Shann Lantee for being yet alive when more important men had not survived.

"I saw the attack from an upper ridge," the younger man said, having been put on the defensive. Yet he had a right to be alive, hadn't he? Or did Thorvald believe that he should have gone running down to meet the beetle-heads with his useless stunner? "They used energy beams ... didn't land until it was all over."

"I knew there was something wrong when the camp didn't answer our enter-atmosphere signal," Thorvald said absently. "Then one of those platters jumped us on braking orbit, and my pilot was killed. When we set down on the automatics here I had just time to rig a surprise for any trackers before I took to the hills——"

"The blast got one of them," Shann pointed out.

"Yes, they'd nicked the booster rocket; she wouldn't climb again. But they'll be back here to pick over the remains."

Shann looked at the dead Throg. "Thanks for taking a hand." His tone was as chill as the other's this time. "I'm heading south...."

And, he added silently, I intend to keep on that way. The Throg attack had dissolved the pattern of the Survey team. He didn't owe Thorvald any allegiance. And he had been successfully on his own here since the camp had been overrun.

"South," Thorvald repeated. "Well, that's as good a direction as any right now."

But they were not united. Shann found the wolverines and patiently coaxed and wheedled them into coming with him over a circuitous route which kept them away from both ships. Thorvald went up the cliff, swung down again, a supply bag slung over one shoulder. He stood watching as Shann brought the animals in.

Then Thorvald's arm swept out, his fingers closing possessively about the barrel of the blaster. Shann's own hold on the weapon tightened, and the force of the other's pull dragged him partly around.

"Let's have that——"

"Why?" Shann supposed that because it had been the other's well-aimed rock which had put the Throg out of commission permanently, the officer was going to claim their only spoils of war as personal booty, and a hot resentment flowered in the younger man.

"We don't take that away from here." Thorvald made the weapon his with a quick twist.

To Shann's utter astonishment, the Survey officer walked back to kneel beside the dead Throg. He worked the grip of the blaster under the alien's lax claws and inspected the result with the care of one arranging a special and highly important display. Shann's protest became vocal. "We'll need that!"

"It'll do us far more good right where it is...." Thorvald paused and then added, with impatience roughening his voice as if he disliked the need for making any explanations, "There is no reason for us to advertise our being alive. If the Throgs found a blaster missing, they'd start thinking and looking around. I want to have a breathing spell before I have to play quarry in one of their hunts."

Put that way, his action did make sense. But Shann regretted the loss of an arm so superior to their own weapons. Now they could not loot the plateship either. In silence he turned and started to trudge southward, without waiting for Thorvald to catch up with him.

Once away from the blasted area, the wolverines ranged ahead at their clumsy gallop, which covered ground at a surprising rate of speed. Shann knew that their curiosity made them scouts surpassing any human and that the men who followed would have ample warning of any danger to come. Without reference to his silent trail companion, he sent the animals toward another strip of woodland which would give them cover against the coming of any Throg flyer.

As the hours advanced he began to cast about for a proper night camp. The woods ought to give them a usable site.

"This is a water wood," Thorvald said, breaking the silence for the first time since they had left the wrecks.

Shann knew that the other had knowledge, not only of the general countryside, but of exploring techniques which he himself did not possess, but to be reminded of that fact was an irritant rather than a reassurance. Without answering, the younger man bored on to locate the water promised.

The wolverines found the small lake first and were splashing along its shore when the Terrans caught up. Thorvald went to work, but to Shann's surprise he did not unstrap the force-blade ax at his belt. Bending over a sapling, he pounded away with a stone at the green wood a few inches above the root line until he was able to break through the slender trunk. Shann drew his own knife and bent to tackle another treelet when Thorvald stopped him with an order: "Use a stone on that, the way I did."

Shann could see no reason for such a laborious process. If Thorvald did not want to use his ax, that was no reason that Shann could not put his heavy belt knife to work. He hesitated, ready to set the blade to the outer bark of the tree.

"Look—" again that impatient edge in the officer's tone, the need for explanation seeming to come very hard to the other—"sooner or later the Throgs might just trace us here and find this camp. If so, they are not going to discover any traces to label us Terran——"

"But who else could we be?" protested Shann. "There is no native race on Warlock."

Thorvald tossed his improvised stone ax from hand to hand.

"But do the Throgs know that?"

The implications, the possibilities, in that idea struck home to Shann. Now he began to understand what Thorvald might be planning.

"Now there is going to be a native race." Shann made a statement instead of a question and saw that the other was watching him with a new intentness, as if he had at last been recognized as a person instead of rank and file and very low rank at that—Survey personnel.

"There is going to be a native race," Thorvald affirmed.

Shann resheathed his knife and went to search the pond beach for a suitable stone to use in its place. Even so, he made harder work of the clumsy chopping than Thorvald had. He worried at one sapling after another until his hands were skinned and his breath came in painful gusts from under aching ribs. Thorvald had gone on to another task, ripping the end of a long tough vine from just under the powdery surface of the thick leaf masses fallen in other years.

With this the officer lashed together the tops of the poles, having planted their splintered butts in the ground, so that he achieved a crudely conical erection. Leafy branches were woven back and forth through this framework, with an entrance, through which one might crawl on hands and knees, left facing the lakeside. The shelter they completed was compact and efficient but totally unlike anything Shann had ever seen before, certainly far removed from the domes of the camp. He said so, nursing his raw hands.

"An old form," Thorvald replied, "native to a primitive race on Terra. Certainly the beetle-heads haven't come across its like before."

"Are we going to stay here? Otherwise it is pretty heavy work for one night's lodging."

Thorvald tested the shelter with a sharp shake. The matted leaves whispered, but the framework held.

"Stage dressing. No, we won't linger here. But it's evidence to support our play. Even a Throg isn't dense enough to believe that natives would make a cross-country trip without leaving evidence of their passing."

Shann sat down with a sigh he made no effort to suppress. He had a vision of Thorvald traveling southward, methodically erecting these huts here and there to confound Throgs who might not ever chance upon them. But already the Survey officer was busy with a new problem.

"We need weapons——"

"We have our stunners, a force ax, and our knives," Shann pointed out. He did not add, as he would have liked that they could have had a blaster.

"Native weapons," Thorvald countered with his usual snap. He went back to the beach and crawled about there, choosing and rejecting stones picked out of the gravel.

Shann scooped out a small pit just before their hut and set about the making of a pocket-sized fire. He was hungry and looked longingly now and again to the supply bag Thorvald had brought with him. Dared he rummage in that for rations? Surely the other would be carrying concentrates.

"Who taught you how to make a fire that way?" Thorvald was back from the pond, a selection of round stones about the size of his fist resting between his chest and his forearm.

"It's regulation, isn't it?" Shann countered defensively.

"It's regulation," Thorvald agreed. He set down his stones in a row and then tossed the supply bag over to his companion. "Too late to hunt tonight. But well have to go easy on those rations until we can get more."

"Where?" Did Thorvald know of some supply cache they could raid?

"From the Throgs," the other answered matter of factly.

"But they don't eat our kind of food...."

"All the more reason for them to leave the camp supplies untouched."

"The camp?"

For the first time Thorvald's lips curved in a shadow smile which was neither joyous nor warming. "A native raid on an invaders' camp. What could be more natural? And we'd better make it soon."

"But how can we?" To Shann what the other proposed was sheer madness.

"There was once an ancient service corps on Terra," Thorvald answered, "which had a motto something like this: 'The improbable we do at once; the impossible takes a little longer.' What did you think we were going to do? Sulk around out here in the bush and let the Throgs claim Warlock for one of their pirate bases without opposition?"

Since that was the only future Shann had visualized, he was ready enough to admit the truth, only some shade of tone in the officer's voice kept him from saying so aloud.



4. SORTIE

Five days later they came up from the south so that this time Shann's view of the Terran camp was from a different angle. At first sight there had been little change in the general scene. He wondered if the aliens were using the Terran dome shelters themselves. Even in the twilight it was easy to pick out such landmarks as the com dome with the shaft of a broadcaster spearing from its top and the greater bulk of the supply warehouse.

"Two of their small flyers down on the landing field...." Thorvald materialized from the shadow, his voice a thread of whisper.

By Shann's side the wolverines were moving restlessly. Since Taggi's attack on the Throg neither beast would venture near any site where they could scent the aliens. This was the nearest point to which the men could urge either animal, which was a disappointment, for the wolverines would have been an excellent addition to the surprise sortie they planned for tonight, halving the danger for the men.

Shann ran his fingers across the coarse fur on the animals' shoulders, exerting a light pressure to signal them to wait. But he was not sure of their obedience. The foray was a crazy idea, and Shann wondered again why he had agreed to it. Yet he had gone along with Thorvald, even suggested a few modifications and additions of his own, such as the contents of the crude leaf sack now resting between his knees.

Thorvald flitted away, seeking his own post to the west. Shann was still waiting for the other's signal when there arose from the camp a sound to chill the flesh of any listener, a wail which could not have come from the throat of any normal living thing, intelligent being or animal. Ululating in ear-torturing intensity, the cry sank to a faint, ominous echo of itself, to waver up the scale again.

The wolverines went mad. Shann had witnessed their quick kills in the wilds, but this stark ferocity of spitting, howling rage was new. They answered that challenge from the camp, streaking out from under his hands. Yet both animals skidded to a stop before they passed the first dome and were lost in the gloom. A spark glowed for an instant to his right; Thorvald was ready to go, so Shann had no time to try and recall the animals.

He fumbled for those balls of soaked moss in his leaf bag. The chemical smell from them blotted out that alien mustiness which the wind brought from the campsite. Shann readied the first sopping mess in his sling, snapped his fire sparker at it, and had the ball awhirl for a toss almost in one continuous movement. The moss burst into fire as it curved out and fell.

To a witness it might have seemed that the missile materialized out of the air, the effect being better than Shann had hoped.

A second ball for the sling—spark ... out ... down. The first had smashed on the ground near the dome of the com station, the force of impact flattening it into a round splatter of now fiercely burning material. And his second, carefully aimed, lit two feet beyond.

Another wail tearing at the nerves. Shann made a third throw, a fourth. He had an audience now. In the light of those pools of fire the Throgs were scuttling back and forth, their hunched bodies casting weird shadows on the dome walls. They were making efforts to douse the fires, but Shann knew from careful experimentation that once ignited the stuff he had skimmed from the lip of one of the hot springs would go on burning as long as a fraction of its viscid substance remained unconsumed.

Now Thorvald had gone into action. A Throg suddenly halted, struggled frantically, and toppled over into the edge of a fire splotch, legs looped together by the coils of the curious weapon Thorvald had put together on their first night of partnership. Three round stones of comparable weight had each been fastened at the end of a vine cord, and those cords united at a center point. Thorvald had demonstrated the effectiveness of his creation by bringing down one of the small "deer" of the grasslands, an animal normally fleet enough to feel safe from both human and animal pursuit. And those weighted ropes now trapped the Throg with the same efficiency.

Having shot his last fireball, Shann ran swiftly to take up a new position, downgrade and to the east of the domes. Here he put into action another of the primitive weapons Thorvald had devised, a spear hurled with a throwing stick, giving it double range and twice as forceful penetration power. The spears themselves were hardly more than crudely shaped lengths of wood, their points charred in the fire. Perhaps these missiles could neither kill nor seriously wound. But more than one thudded home in a satisfactory fashion against the curving back carapace or the softer front parts of a Throg in a manner which certainly shook up and bruised the target. And one of Shann's victims went to the ground, to lie kicking in a way which suggested he had been more than just bruised.

Fireballs, spears.... Thorvald had moved too. And now down into the somewhat frantic melee of the aroused camp fell a shower of slim weighted reeds, each provided with a clay-ball head. The majority of those balls broke on landing as the Terrans had intended. So, through the beetle smell of the aliens, spread the acrid, throat-parching fumes of the hot spring water. Whether those fumes had the same effect upon Throg breathing apparatus as they did upon Terran, the attackers could not tell, but they hoped such a bombardment would add to the general confusion.

Shann began to space the hurling of his crude spears with more care, trying to place them with all the precision of aim he could muster. There was a limit to their amount of varied ammunition, although they had dedicated every waking moment of the past few days to manufacture and testing. Luckily the enemy had had none of their energy beams at the domes. And so far they had made no move to lift their flyers for retaliation blasts.

But the Throgs were pulling themselves into order. Blaster fire cut the dusk. Most of the aliens were now flat on the ground, sending a creeping line of fire into the perimeter of the camp area. A dark form moved between Shann and the nearest patch of burning moss. The Terran raised a spear to the ready before he caught a whiff of the pungent scent emitted by a wolverine hot with battle rage. He whistled coaxingly. With the Throgs eager to blast any moving thing, the animals were in danger if they prowled about the scene.

That blunt head moved. Shann caught the glint of eyes in a furred mask; it was either Taggi or his mate. Then a puff of mixed Throng and chemical scent from the camp must have reached the wolverine. The animal coughed and fled westward, passing Shann.

Had Thorvald had time and opportunity to make his planned raid on the supply dome? Time during such an embroilment was hard to measure, and Shann could not be sure. He began to count aloud, slowly, as they had agreed. When he reached one hundred he would begin his retreat; on two hundred he was to run for it, his goal the river a half mile from the camp.

The stream would take the fugitives to the sea where fiords cut the coastline into a ragged fringe offering a wealth of hiding places. Throgs seldom explored any territory on foot. For them to venture into that maze would be putting themselves at the mercy of the Terrans they hunted. And their flyers could comb the air above such a rocky wilderness without result.

Shann reached the count of one hundred. Twice a blaster bolt singed ground within distance close enough to make him wince, but most of the fire carried well above his head. All of his spears were gone, save for one he had kept, hoping for a last good target. One of the Throgs who appeared to be directing the fire of the others was facing Shann's position. And on pure chance that he might knock out that leader, Shann chose him for his victim.

The Terran had no illusions concerning his own marksmanship. The most he could hope for, he thought, was to have the primitive weapon thud home painfully on the other's armored hide. Perhaps, if he were very lucky, he could knock the other from his clawed feet. But that chance which hovers over any battlefield turned in Shann's favor. At just the right moment the Throg stretched his head up from the usual hunched position where the carapace extended over his wide shoulders to protect one of the alien's few vulnerable spots, the soft underside of his throat. And the fire-sharpened point of the spear went deep.

Throgs were mute, or at least none of them had ever uttered a vocal sound to be reported by Terrans. This one did not cry out. But he staggered forward, forelimbs up, clawed digits pulling at the wooden pin transfixing his throat just under the mandible-equipped jaw, holding his head at an unnatural angle. Without seeming to notice the others of his kind, the Throg came on at a shambling run, straight at Shann as if he could actually see through the dark and had marked down the Terran for personal vengeance. There was something so uncanny about that forward dash that Shann retreated. As his hand groped for the knife at his belt his boot heel caught in a tangle of weed and he struggled for balance. The wounded Throg, still pulling at the spear shaft protruding above the swelling barrel of his chest, pounded on.

Shann sprawled backward and was caught in the elastic embrace of a bush, so he did not strike the ground. He fought the grip of prickly branches and kicked to gain solid earth under his feet. Then again he heard that piercing wail from the camp, as chilling as it had been the first time. Spurred by that, he won free. But he could not turn his back on the wounded Throg, keeping rather a sidewise retreat.

Already the alien had reached the dark beyond the rim of the camp. His progress now was marked by the crashing through low brush. Two of the Throgs back on the firing line started up after their leader. Shann caught a whiff of their odor as the wounded alien advanced with the single-mindedness of a robot.

It would be best to head for the river. Tall grass twisted about the Terran's legs as he began to run. In spite of the gloom, he hesitated to cross that open space. At night Warlock's peculiar vegetation displayed a very alien attribute—ten ... twenty varieties of grass, plant, and tree emitted a wan phosphorescence, varying in degree, but affording each an aura of light. And the path before Shann now was dotted by splotches of that radiance, not as brilliant as the chemical-born flames the attackers had kindled in the camp, but as quick to betray the unwary who passed within their dim circles. And there had never been any reason to believe that Throg powers of sight were less than human; there was perhaps some evidence to the contrary. Shann crouched, charting the clumps ahead for a zigzag course which would take him to at least momentary safety in the river bed.

Perhaps a mile downstream was the transport the Terrans had cobbled together no earlier than this afternoon, a raft Thorvald had professed to believe would support them to the sea which lay some fifty Terran miles to the west. But now he had to cover that mile.

The wolverines? Thorvald? There was one lure which might draw the animals on to the rendezvous. Taggi had brought down a "deer" just before they had left the raft. And instead of allowing both beasts to feast at leisure, Shann had lashed the carcass to the shaky platform of wood and brush, putting it out to swing in the current, though still moored to the bank.

Wolverines always cached that part of the kill which they did not consume at the first eating, usually burying it. He had hoped that to leave the carcass in such a way would draw both animals back to the raft when they were hungry. And they had not fed particularly well that day.

Thorvald? Well, the Survey officer had made it very plain during the past five days of what Shann had come to look upon as an uneasy partnership that he considered himself far abler to manage in the field, while he had grave doubts of Shann's efficiency in the direction of survival potential.

The Terran started along the pattern of retreat he had laid out to the river bed. His heart pounded as he ran, not because of the physical effort he was expending, but because again from the camp had come that blood-freezing howl. A lighter line marked the lip of the cut in which the stream was set, something he had not foreseen. He threw himself down to crawl the last few feet, hugging the earth.

That very pale luminescence was easily accounted for by what lay below. Shann licked his lips and tasted the sting of sap smeared on his face during his struggle with the bushes. While the strip of meadow behind him now had been spotted with light plants, the cut below showed an almost solid line of them stringing willow-wise along the water's edge. To go down at this point was simply to spotlight his presence for any Throg on his trail. He could only continue along the upper bank, hoping to finally find an end to the growth of luminescent vegetation below.

Shann was perhaps five yards from the point where he had come to the river, when a commotion behind made him freeze and turn his head cautiously. The camp was half hidden, and the fires there must be dying. But a twisting, struggling mass was rolling across the meadow in his general direction.

Thorvald fighting off an attack? The wolverines? Shann drew his legs under him, ready to erupt into a counter-offensive. He hesitated between drawing stunner or knife. In his brush with the injured Throg at the wreck the stunner had had little impression on the enemy. And now he wondered if his blade, though it was super-steel at its toughest, could pierce any joint in the armored bodies of the aliens.

There was surely a fight in progress. The whole crazily weaving blot collapsed and rolled down upon three bright light plants. Dull sheen of Throg casing was revealed ... no sign of fur, or flesh, or clothing. Two of the aliens battling? But why?

One of those figures got up stiffly, bent over the huddle still on the ground, and pulled at something. The wooden shaft of Shann's spear was wanly visible. And the form on the ground did not stir as that was jerked loose. The Throg leader dead? Shann hoped so. He slid his knife back into the sheath, tapped the hilt to make sure it was firmly in place, and crawled on. The river, twisting here and there, was a promising pool of dusky shadow ahead. The bank of willow-things was coming to an end, and none too soon. For when he glanced back again he saw another Throg run across the meadow, and he watched them lift their fellow, carrying him back to camp.

The Throgs might seem indestructible, but he had put an end to one, aided by luck and a very rough weapon. With that to bolster his self-confidence to a higher notch, Shann dropped by cautious degrees over the bank and down to the water's edge. When his boots splashed into the oily flood he began to tramp downstream, feeling the pull of the water, first ankle high and then about his calves. This early in the season they did hot have to fear floods, and hereabouts the stream was wide and shallow, save in mid-current at the center point.

Twice more he had to skirt patches of light plants, and once a young tree stood bathed in radiance with a pinkish tinge instead of the usual ghostly gray. Within the haze which tented the drooping branches, flitted small glittering, flying things; and the scent of its half-open buds was heavy on the air, neither pleasant nor unpleasant in Shann's nostrils, merely different.

He dared to whistle, a soft call he hoped would carry along the cut between the high banks. But, though he paused and listened until it seemed that every cell in his thin body was occupied in that act, he heard no answering call from the wolverines, nor any suggestion that either the animals or Thorvald were headed in the direction of the raft.

What was he going to do if none of the others joined him downstream? Thorvald had said not to linger there past daylight. Yet Shann knew that unless he actually sighted a Throg patrol splashing after him he would wait until he made sure of the others' fate. Both Taggi and Togi were as important to him as the Survey officer. Perhaps more so, he told himself now, because he understood them to a certain degree and found companionship in their undemanding company which he could not claim from the man.

Why did Thorvald insist upon their going on to the seashore? To Shann's mind his own first plan of holing up back in the eastern mountains was better. Those heights had as many hiding places as the fiord country. But Thorvald had suddenly become so set on this westward trek that he had given in. As much as he inwardly rebelled when he took them, he found himself obeying the older man's orders. It was only when he was alone, as now, that he began to question both Thorvald's motives and his authority.

Three sprigs of a light bush set in a triangle. Shann paused and then climbed out on the bank, shaking the water from his boots as Taggi might shake such drops from a furred limb. This was the sign they had set to mark their rendezvous point, but....

Shann whirled, drawing his stunner. The raft was a dark blob on the surface of the water some feet farther on. And now it was bobbing up and down violently. That was not the result of any normal tug of current. He heard an indignant squeal and relaxed with a little laugh. He need not have worried about the wolverines; that bait had drawn them all right. Both of them were now engaged in eating, though they had to conduct their feast on the rather shaky foundation of the makeshift transport.

They paid no attention as he waded out, pulling at the anchor cord as he went. The wind must have carried his familiar scent to them. As the water climbed to his shoulders Shann put one hand on the outmost log of the raft. One of the animals snarled a warning at being disturbed. Or had that been at him?

Shann stood where he was, listening intently. Yes, there was a splashing sound from upstream. Whoever followed his own recent trail was taking no care to keep that pursuit a secret, and the pace of the newcomer was fast enough to spell trouble.

Throgs? Tensely the Terran waited for some reaction from the wolverines. He was sure that if the aliens had followed him, both animals would give warning. Save when they had gone wild upon hearing that strange wail from the camp, they avoided meeting the enemy.

But from all sounds the animals had not stopped feeding. So the other was no beetle-head. On the other hand, why would Thorvald so advertise his coming, unless the need for speed was greater than caution? Shann drew taut the mooring cord, bringing out his knife to saw through that tough length. A figure passed the three-sprig signal, ran onto the raft.

"Lantee?" The call came in a hoarse, demanding whisper.

"Here."

"Cut loose. We have to get out of here!"

Thorvald flung himself forward, and together the men scrambled up on the raft. The mangled carcass plunged into the water, dislodged by their efforts. But before the wolverines could follow it, the mooring vine snapped, and the river current took them. Feeling the raft sway and begin to spin, the wolverines whined, crouched in the middle of what now seemed a very frail craft.

Behind them, far away but too clear, sounded that eerie howling, topping the sigh of the night wind.

"I saw——" Thorvald gasped, pausing as if to catch full lungfuls of air to back his words, "they have a 'hound!' That's what you hear."



5. PURSUIT

As the raft revolved slowly it also slipped downstream at a steadily increasing pace, for the current had them in hold. The wolverines pressed close to Shann until the musky scent of their fur, their animal warmth, enveloped him. One growled deep in its throat, perhaps in answer to that wind-borne wail.

"Hound?" Shann asked.

Beside him in the dark Thorvald was working loose one of the poles they had readied to help control the raft's voyaging. The current carried them along, but there was a need for those lengths of sapling to fend them free from rocks and water-buried snags.

"What hound?" the younger man demanded more sharply when there came no immediate answer.

"The Throgs' tracker. But why did they import one?" Thorvald's puzzlement was plain in his tone. He added a moment later, with some of his usual firmness, "We may be in for bad trouble now. Use of a hound means an attempt to take prisoners——"

"Then they do not know that we are here, as Terrans, I mean?"

Thorvald seemed to be sorting out his thoughts when he replied to that. "They could have brought a hound here just on chance that they might miss one of us in the initial mop-up. Or, if they believe we are natives, they could want a specimen for study."

"Wouldn't they just blast down Terrans on sight?"

Shann saw the dark blot which was Thorvald's head shake in negation.

"They might need a live Terran—badly and soon."

"Why?"

"To operate the camp call beam."

Shann's momentary bewilderment vanished. He knew enough of Survey procedure to guess the reason for such a move on the part of the aliens.

"The settler transport?"

"Yes, the ship. She won't planet here without the proper signal. And the Throgs can't give that. If they don't take her, their time's run out before they have even made a start here."

"But how could they know that the transport is nearly due? When we intercept their calls they're pure gibberish to us. Can they read our codes?"

"The supposition is that they can't. Only, concerning Throgs, all we know is supposition. Anyway, they do know the routine for establishing a Terran colony, and we can't alter that procedure except in small nonessentials," Thorvald said grimly. "If that transport doesn't pick up the proper signal to set down here on schedule, her captain will call in the patrol escort ... then exit one Throg base. But if the beetle-heads can trick the ship in and take her, then they'll have a clear five or six more months here to consolidate their own position. After that it would take more than just one patrol cruiser to clear Warlock; it will require a fleet. So the Throgs will have another world to play with, and an important one. This lies on a direct line between the Odin and Kulkulkan systems. A Throg base on such a trade route could eventually cut us right out of this quarter of the galaxy."

"So you think they want to capture us in order to bring the transport in?"

"By our type of reasoning, that would be a logical move—if they know we are here. They haven't too many of those hounds, and they don't risk them on petty jobs. I'd hoped we'd covered our trail well. But we had to risk that attack on the camp.... I needed the map case!" Again Thorvald might have been talking to himself. "Time ... and the right maps—" he brought his fist down on the raft, making the platform tremble—"that's what I have to have now."

Another patch of light-willows stretched along the river-banks, and as they sailed through that ribbon of ghostly radiance they could see each other's faces. Thorvald's was bleak, hard, his eyes on the stream behind them as if he expected at any moment to see a Throg emerge from the surface of the water.

"Suppose that thing—" Shann pointed upstream with his chin—"follows us? What is it anyway?" Hound suggested Terran dog, but he couldn't stretch his imagination to believe in a working co-operation between Throg and any mammal.

"A rather spectacular combination of toad and lizard, with a few other grisly touches, is about as close as you can get to a general description. And that won't be too accurate, because like the Throgs its remote ancestors must have been of the insect family. If the thing follows us, and I think we can be sure that it will, we'll have to take steps. There is always this advantage—those hounds cannot be controlled from a flyer, and the beetle-heads never take kindly to foot slogging. So we won't have to expect any speedy chase. If it slips its masters in rough country, we can try to ambush it." In the dim light Thorvald was frowning. "I flew over the territory ahead on two sweeps, and it is a queer mixture. If we can reach the rough country bordering the sea, we'll have won the first round. I don't believe that the Throgs will be in a hurry to track us in there. They'll try two alternatives to chasing us on foot. One, use their energy beams to rake any suspect valley, and since there are hundreds of valleys all pretty much alike, that will take some time. Or they can attempt to shake us out with a dumdum should they have one here, which I doubt."

Shann tensed. The stories of the effects of the Throg's dumdum weapon were anything but pretty.

"And to get a dumdum," Thorvald continued as if he were discussing a purely theoretical matter and not a threat of something worse than death, "They'll have to bring in one of their major ships. Which they will hesitate to do with a cruiser near at hand. Our own danger spot now is the section we should strike soon after dawn tomorrow if the rate of this current is what I have timed it. There is a band of desert on this side of the mountains. The river gorge deepens there and the land is bare. Let them send a ship over and we could be as visible as if we were sending up flares——"

"How about taking cover now and going on only at night?" suggested Shann.

"Ordinarily, I'd say yes. But with time pressing us now, no. If we keep straight on, we could reach the foothills in about forty hours, maybe less. And we have to stay with the river. To strike across country there without good supplies and on foot is sheer folly."

Two days. With perhaps the Throgs unleashing their hound on land, combing from their flyers. With a desert.... Shann put out his hands to the wolverines. The prospect certainly didn't seem anywhere near as simple as it had the night before when Thorvald had planned this escape. But then the Survey officer had left out quite a few points which were not pertinent. Was he also leaving out other essentials? Shann wanted to ask, but somehow he could not.

After a while he dozed, his head resting on his knees. He awoke, roused out of a vivid dream, a dream so detailed and so deeply impressed in a picture on his mind that he was confused when he blinked at the riverbank visible in the half-light of early dawn.

Instead of that stretch of earth and ragged vegetation now gliding past him as the raft angled along, he should have been fronting a vast skull stark against the sky—a skull whose outlines were oddly inhuman, from whose eyeholes issued and returned flying things while its sharply protruding lower jaw was lapped by water. In color that skull had been a violent clash of blood-red and purple. Shann blinked again at the riverbank, seeing transposed on it still that ghostly haze of bone-bare dome, cavernous eyeholes and nose slit, fanged jaws. That skull was a mountain, or a mountain was a skull—and it was important to him; he must locate it!

He moved stiffly, his legs and arms cramped but not cold. The wolverines stirred on either side of him. Thorvald continued to sleep, curled up beyond, the pole still clasped in his hands. A flat map case was slung by a strap about his neck, its thin envelope between his arm and his body as if for safekeeping. On the smooth flap was the Survey seal, and it was fastened with a finger lock.

Thorvald had lost some of the bright hard surface he had shown at the spaceport where Shann had first sighted him. There were hollows in his cheeks, sending into high relief those bone ridges beneath his eye sockets, giving him a faint resemblance to the skull of Shann's dream. His face was grimed, his field uniform stained and torn. Only his hair was as bright as ever.

Shann smeared the back of his hand across his own face, not doubting that he must present an even more disreputable appearance. He leaned forward cautiously to look into the water, but that surface was not quiet enough to act as a mirror.

Getting to his feet as the raft bobbed under his shift of weight, Shann studied the territory now about them. He could not match Thorvald's inches, just as he must have a third less bulk than the officer, but standing, he could sight something of what now lay beyond the rising banks of the cut. That grass which had been so thick in the meadowlands around the camp had thinned into separate clumps, pale lavender in color. And the scrawniness of stem and blade suggested dehydration and poor soil. The earth showing between those clumps was not of the usual blue, but pallid, too, bleached to gray, while the bushes along the stream's edge were few and smaller. They must have crossed the line into the desert Thorvald had promised.

Shann edged around to face west. There was light enough in the sky to sight tall black pyramids waiting. They had to reach those distant mountains, mountains whose feet on the other side were resting in sea water. He studied them carefully, surveying each peak he could separate from its fellows.

Did the skull lie among them? The conviction that the place he had seen in his dream was real, that it was to be found on Warlock, persisted. Not only was it a definite feature of the landscape somewhere in the wild places of this world, but it was also necessary for him to locate it. Why? Shann puzzled over that, with a growing uneasiness which was not quite fear, not yet, anyway.

Thorvald moved. The raft tilted and the wolverines became growly. Shann sat down, one hand out to the officer's shoulder in warning. Feeling that touch Thorvald shifted, one hand striking out blindly in a blow which Shann was just able to avoid while with the other he pinned the map case yet tighter to him.

"Take it easy!" Shann urged.

The other's eyelids flicked. He looked up, but not as if he saw Shann at all.

"The Cavern of the Veil——" he muttered. "Utgard...." Then his eyes did focus and he sat up, gazing around him with a frown.

"We're in the desert," Shann announced.

Thorvald got up, balancing on feet planted a little apart, looking to the faded expanse of the waste spreading from the river cut. He stared at the mountains before he squatted down to fumble with the lock of the map case.

The wolverines were growing restless, though they still did not try to move about too freely on the raft, greeting Shann with vocal complaint. He and Thorvald could satisfy their hunger with a handful of concentrates from the survival kit. But those dry tablets could not serve the animals. Shann studied the terrain with more knowledge than he had possessed a week earlier. This was not hunting land, but there remained the bounty of the river.

"We'll have to feed Taggi and Togi," he broke the silence abruptly. "If we don't, they'll be into the river and off on their own."
