  It began to snow again, and he welcomed that together with the dark. Both made a curtain behind which he could move faster. The wall of the valley was curving, and he believed that the voice sounded closer.

  He rounded a spur and looked out into another stretch of open. But here there were no bushes, save for some withered stalks very close to him. And the look of those— Diskan pushed out his club and caught the nearest stalk. At a very slight pressure on his part, it snapped, and he pulled it to him.

  Burned! It had the same appearance as the seared vegetation he had seen near the crash of the spacer. He rubbed the charred stick between thumb and forefinger and eyed that open space narrowly. Level—unusually level—more so than any other site he had seen in this new world. A good place to plant a ship. Was that it? Could this be where a spacer had finned in and then lifted again? Snow covered any rocket scars, but it was just possible his guess was right.

  Once more that unintelligible message rang through the still air, though now it sounded somewhat muffled, as if the falling snow deadened the broadcast. Diskan stood up, daring now to take the chance.

  He plunged forward, across the narrowest end of the open expanse, blundering into more burned brush on the far side. Then he saw through the dim light a half bubble that was a familiar thing from his own past. That was a temporary shelter such as he had seen in the tri-dee tapes. It was windowless and doorless, but somewhere along its surface, an entrance would yield to the heat and pressure of a hand. This was a rescue cache, established as a refuge for the survivors of some ship crash. Perhaps more than one spacer had fallen into a mud bog on this unknown world.

  And Diskan could understand the need for that broadcast now, even if he did not know the words. It was a set signal to draw any survivors to the refuge. And surely, since the call still sounded, the cache cabin was not in use.

  With numb fingers and his teeth, Diskan ripped the cocoon windings from his hand and set it against the surface of the cache at waist level, slipping it along the bubble as he began circling the shelter. Unlike a more permanent erection, any seal would be attuned to the general body heat and not to a palm pattern of an individual man or men. When he found the lock, it should yield to him. Then, food, clothing, arms —perhaps everything he needed—would be his.

  How long had this stood here broadcasting its call? And why had it been left? A ship downed here, sending out an SOS—then arrival of a rescue force, perhaps a Patrol cruiser? unable to find any survivors, but evidence that such had existed, had they set up the cache and blasted off, expecting to return later? He could string those guesses together into a plausible explanation—except for the fact that the broadcast was not couched in Basic, as it should be for a Service rescue cache.

  Diskan had a poor education, but Basic, as well as native planet speech, was hypo-taught to every child as soon as he began to talk. And there were no space-going people now, human or nonhuman, who did not use Basic as the common tongue, though it might be necessary for some aliens to resort to mechanical means for translation. So, why not Basic for the beacon call of a cache?

  His questing hand suddenly slipped into a hollow his eyes could not distinguish in the fabric of the cache. It did not feel large enough, that hollow, but he pressed his bare palm as tightly as he could into the narrow space. He had found the lock—now for the unlocking.

  A slow glow spread up the walls. Then, as abruptly as a snap of fingers, a narrow slit opened before him, and Diskan edged through—into light, heat, smells. The wall closed behind him as he stood looking about the refuge.

  Food—he wanted that first. Diskan took a step or two away from the now resealed door, and then his legs gave out, and he swayed and fell. The light was dazzling; it hurt his eyes. He levered himself up on his hands, to blink at the array of containers jumbled altogether, as if hastily dumped.

  Pulling himself to the nearest, a broad cylinder, Diskan forced up the snap lid. More containers, rammed in carelessly. Among them he recognized one, pried it out of the confusion, and triggered the small button on its side.

  Minutes later he was gulping a reviving liquid that tasted like a richly flavored stew and that was intended, Diskan knew, as Sustain food for survivor use. Having finished its contents, he returned to the unpacking of the cylinder. But as he handled each tube, can, and box he pulled from that inner disorder, his surprise grew, and with it an uneasiness.

  Some of these supplies he knew, but most of them he did not. Not only that, but the unknown items varied among themselves, too. He was sure that the strange identification symbols differed greatly, so that he might now be sorting over rations for a score of races, even of species. Did that mean that the survivors these were intended to succor had been a mixed lot—alien, human, and grades in between? But only a crack liner would carry so widely differing a set of passengers on just one voyage.

  And the loss of such a liner would have been news reaching even to Vaanchard. Or—Diskan frowned as he set out that bewildering array of containers—or had such a crash occurred as he voyaged in freeze through space?

  But a liner carried a thousand or more passengers. This cache could not contain supplies for that many. Had one lifeboat with a highly mixed crowd set down here? That might be it. Only—why not then broadcast in Basic? It did not fit.

  And none of the rations he did know bore the seal of the Patrol—which they surely would have done had this been a Service cache. The way they had been slung into this cylinder, not packed, but crammed—Diskan began to sort them. Surely there was more than one unknown tongue on the labels. He pressed the heat-serve button on a second tube and ate its contents slowly, while he studied the display. When he had finished, he restored the unknown rations to the cylinder.

  Then, methodically, he began to rummage through the other containers of the cache—to discover that all but three of those were palm-sealed to a personal print code! Then this could not be a Service cache or all contents would be free to anyone managing to make the shelter! This was a cache, right enough, but intended not for any survivor of a space disaster—no, for some special survivors.

  Some of the things he had uncovered he could use. There was a parka-coat of Orkanza hide with an inner stuffing of insulating Com moss—a little tight across the shoulders, but he could wriggle into it. Boots of the same Orkanza hide made watertight by sal-fat grease were too small. Regretfully, he had to set those aside. Pushed down under them was a tunic. Diskan spread that out across his knee, and his uneasiness sharpened.

  This was a dress tunic, a refinement of Ozackian spider silk—or something quite close to that fabulous, and very expensive, fabric. There was a tracery of embroidery about the high collar and around the breast latches that made a lacy pattern composed of hundreds of minute gems threaded on the silk. Only a Veep would wear a garment such as this. Yet there was a spot on the front, a stain that was greasy to the touch, as if food had been carelessly spattered there.

  Diskan folded the tunic and put it with the boots. He found two sleep bags, both too small, but which, put together, would give him a better bed than he had known in many days. But—there were no weapons, no tools, unless both were in the locked boxes. He had food, a new coat, and a big puzzle.

  He tried to pry open one of the sealed boxes, using the sharpened point of his improvised spear, only stopping when the wood seemed likely to crack. Primitive as that weapon was, it had to serve him, since the cache could not offer better. Diskan padded the two bed rolls together and then set about moving some of the containers so that anyone entering the shelter would take a tumble to announce his arrival. He stretched out on the bed with a sigh of satisfaction.

  In spite of the light still glowing in the walls, he slept— but not to wander in a dream city. Outside the core of warmth, the snow continued to fall, blotting out his own tracks to the cache.

  But in the night, others were astir; communication traveled, but not by spoken word. Forces met, moved, parted. Impatience, anger colored the discussion
. And then watchers settled into place around the cache and what it held—so important to their purposes.

  Diskan stirred, rolled over, blinked at the shaky pyramid of boxes of which he had made his alarm. The light of the walls remained the same—but something was different. He sat up and looked around the bubble with more sharply focused attention. As far as he could remember, it was the same. Surely no one had tried to enter, or that box pile would have fallen.

  Quiet enough—that was it, quiet! The broadcast that had drawn him here had ceased to function. He no longer heard that murmur of sound, reduced to a hum by the walls of the shelter. Perhaps his entrance had stopped it.

  Why that was making him wary he did not know. But now, trying to remember what had happened up to the point of his falling asleep, Diskan was sure that that murmur had continued after he had entered the bubble. So, his entrance had not automatically silenced it.

  He had never believed that he possessed too vivid an imagination, but now it seemed to him that the silence of the broadcast could act as a signal by its very absence. Suppose, just suppose, that somewhere else on this world there was a settlement or camp, in automatic communication with the cache—so that when it was entered, the camp was notified. A cache could also be a trap!

  Diskan went to the pile of rations and then took up the torn cloak of cocoon stuff, tying in into a bag into which he crammed the supplies. The thought of a trap had settled so in his mind that he thought it a fact. Why it had been set, and for whom, did not matter; getting out of it at once did.

  With the parka tight about his shoulders and chest, the bulky bag and his club in his hands, he set his palm to the door. The slit opened, and he came out into day and snow that was knee deep.

  No matter what, he was going to leave tracks through this unless another storm covered them. There was a grove of trees before him, not the red-leafed kind, but a mass of a bare-branched, thick-standing species. To get into that grove could mean losing all sense of direction. He must keep in the open and head for the heights from which he had come. In and among those rocks spires would be a good many hiding places.

  Having made his decision, Diskan struck out through the puffy snow. It was far harder than it had first seemed, this tramping through drifts. The snow was damp and heavy, clinging to his legs, working into the tops of his boots, caking on the edge of the parka. Twice he fell when footing suddenly sank under him. But he kept going, past the space where he was sure an off-world ship or ships had set down, heading for the rock wall and those eroded pillars marking the ancient road.

  He was perhaps two-thirds of the way to that goal when the beacon voice spoke, startling him so much that he lost his balance for a third time and toppled into a drift high enough to engulf him. As he fought his way out, he listened. Were those the same words he had heard the night before or were they different? Diskan discovered that he could not depend upon his memory. They could be different—first announcing his coming and now his going.

  But to put on more speed was impossible; he could wade at hardly more than a strolling pace. And twice, when he halted to breathe, he studied the way ahead anxiously. There seemed to be any number of pillar-like formations, all crowned with lumps of snow. Then he knew he was lost.

  All right, he did not really need the pillars. At any climbable point, he could find a way back up the slope, and from there he could watch the cache throughout the day. Then, if there were no visitors, at nightfall he could return to shelter in it. Up there, he could watch his own back trail, be sure he was not hunted.

  To any Patrol officer, he would be a prisoner, but he was sure that the cache was not Patrol. Perhaps to anyone else, he could pose as a survivor from a lifeboat landing. Diskan smiled. He had all day to think up a good story and settle all its details so deeply in mind that he could reel it off with convincing force. He began to climb.

  Three times he moved before he found what he deemed the perfect lookout. Though he had no farseeing lenses, the valley spread out below this perch as a white map, broken only by his own trail. He triggered open a ration tube and ate. Of course he could not see the cache from here—but he did hear the broadcast droning through the crisp air.

  But it grew monotonous, this staring at the snow and his tracks through it. Diskan wished he did have lenses and could see what lay beyond the tangled wood he had feared to enter. Now and again he watched the sky, once stiffening as a flying thing swooped, until he saw it was no machine but one of the red birds.

  As the hours he could not measure wore on, Diskan began to believe his fears of the morning rootless. The voice continued to sound; there was no sign of anyone coming along his trail. There might well be no one but himself of off-world origin on this whole planet. It was cold up here; he might be wasting a whole day to no purpose. Yet he did not want to go back to the cache—not now, anyway. Time enough to return when night closed in. He could do it cleverly, using the same trail back—

  It was hard to just sit here, waiting. He studied the part of the valley he could see clearly. It might be wise for him to move along the heights and come up to the cache from another direction. Diskan repacked his supplies into a bag of smaller compress, shouldered the bundle, and began to move, trying to keep to cover, as if he were a Scout moving through enemy territory—though he could not put name to that enemy, nor explain why he was convinced of the need for not revealing his presence.

  But he had watchers who knew a kindling of triumph. Their quarry was on the move again—in the right direction.

  VII

  Diskan must have been on the trail for some time before he saw, beneath the patches of snow and the spotty growth, indications that he was again following a road—not a trail such as animals would make, but one fashioned of blocks of pavement, no longer aligned, yet present. Even in this state, it was easier footing than the cliff edge, and he could make better time, though it struck away at an angle from his course.

  The broadcast reached him now as a booming noise in which he could no longer separate the words. And to that, the wind whistling among the rock pillars made a shrill accompaniment.

  But the squall that halted him, almost in midstep, was neither voice nor wind. The road entered a cut between two rock spurs, and facing him at the far end of that cut—

  Diskan went into a half crouch, his wooden weapon in both hands, the splintered point foremost. The thing was big, much larger than the creature that had accompanied him before. It stood erect, on two stumpy hind legs, so thick with fur that they looked straight. In contrast, its belly was naked and a dull, unhealthy-looking yellow, with small flecks, as if it were coated with scales. Like the scavengers, the creature was, to Diskan's off-world eyes, an unwholesome mixture of animal and reptile.

  The head narrowed from a brush of upstanding ragged skin to a snout, where fangs curved up to make a white fringe about yellow lips. But the worst was that it moved forward on its hind legs, its action grotesquely human, its well-armored forepaws raised a little in front of its chest as if it were about to attack him with fists.

  That armored snout opened to emit, not the squall Diskan had heard, but a very reptilian hiss, its breath forming a steamy cloud. It was fully his height, or perhaps an inch or so more. And Diskan had no doubt that once within reach of those claws, he had only a slight chance of survival.

  Still facing the beast, he withdrew step by step. Luckily, the thing seemed to be in no hurry to close the distance between them. It matched him step by step, and save for the hissing, it gave no sign of active hostility. But he knew he had good reason to fear it.

  Back—now he was out of the beginning of the cut, in a place that gave him more room to dodge any rush. He was sure he dared not turn his back and run—such a move would merely bring the enemy to attack. Whether the thing was fast on its feet, he could not tell, but it was fighting in its own territory and had the advantage.

  There was space to Diskan's right between two rocks, a narrow slit offering a bolt hole., Diskan backed towa
rd that. The bushy head was sinking between the thing's shoulders. Its hissing climbed to a high note and was almost continuous. It was working itself up to a charge, he was sure.

  He was in the crevice now, the wooden spear centered on the beast's midsection. The footing was rough here; he had to glance down now and then to assure himself. And each time he did that, he gave the enemy a second or two of advantage.

  Again that other squall. Seemingly out of the air a dark body appeared between Diskan and the menace. Back arched, thin tail whipping back and forth in rage, fangs bared, snarling in a rising crescendo of sound, was the furred animal, or one of its kind.

  The hissing of the attacker was terrible. And the creature struck with a speed Diskan had not granted its rather clumsy-looking body. Claws curved down, but not into flesh as their owner had intended, for the furred one had dodged with lightning speed, sprung somehow under that blow to strike in turn at the naked yellow belly, opening a spurting slash there. Huge feet stamped, kicked, but the smaller animal had another chance at the big one and opened a second dripping wound.

  Only this time it was not so lucky. Claws caught in its fur and swung it off the ground, up to the level of waiting jaws, in spite of its writhing, its flailing paws. Diskan acted. It did not occur to him to leave the two beasts locked in battle, making good his escape. Instead, he leaped forward, his puny weapon ready.

  He could not get close to the struggle, but he thrust as true as he could for one of the wide eyes in that head now bending over the fiercely fighting captive. The spear did not go home as he had hoped, but its point raked across the eyeball. The creature gave a fearsome cry and flung up its head.

  Diskan stabbed again, trying for a spot beneath that upheld head. He had some dim idea that might be a soft place in the creature's body armor. His spear met opposition, did not even penetrate that deceptively naked-looking skin, but the force he had managed to put into the thrust ended the hissing in an explosive grunt.
