But that night Shann dreamed. No climbing of a skull-shaped mountain this time. Instead, he was again on the beach, laboring under an overwhelming compulsion, building something for an alien purpose he could not understand. And he worked as hopelessly as a beaten slave, knowing that what he made was to his own undoing. Yet he could not halt the making, because just beyond the limit of his vision there stood a dominant will which held him in bondage.

  And he awoke on the beach in the very early dawn, not knowing how he had come there. His body was bathed in sweat, as it had been during his day's labors under the sun, and his muscles ached with fatigue.

  But when he saw what lay at his feet he cringed. The framework of the outrigger, close to completion the night before, was dismantled—smashed. All those strips of hide he had so laboriously culled were cut—into inch-long bits which could be of no service.

  Shann whirled, ran to the shell he had the night before pulled from the water and stowed in safety. Its rounded dome was dulled where it had been battered, but there was no break in the surface. He ran his hands anxiously over the curve to make sure. Then, very slowly, he came back to the mess of broken wood and snipped hide. And he was sure, only too sure, of one thing. He, himself, had wrought that destruction. In his dream he had built to satisfy the whim of an enemy; in reality he had destroyed; and that was also, he believed, to satisfy an enemy.

  The dream was a part of it. But who or what could set a man dreaming and so take over his body, make him in fact betray himself? But then, what had made Thorvald maroon him here? For the first time, Shann guessed a new, if wild, explanation for the officer's desertion. Dreams—and the disk which had worked so strangely on Thorvald. Suppose everything the other had surmised was the truth! Then that disk had been found on this very island, and here somewhere must lie a clue to the riddle.

  Shann licked his lips. Suppose that Thorvald had been sent away under just such a strong compulsion as the one which had ruled Shann last night? Why was he left behind if the other had been moved away to protect some secret? Was it that Shann himself was wanted here, wanted so much that when he at last found a means of escape he was set to destroy it? That act might have been forced upon him for two reasons: to keep him here, and to impress upon him how powerless he was.

  Powerless! A flicker of stubborn will stirred to respond to that implied challenge. All right, the mysterious they had made him do this. But they had underrated him by letting him learn, almost contemptuously, of their presence by that revelation. So warned, he was in a manner armed; he could prepare to fight back.

  He squatted by the wreckage as he thought that through, turning over broken pieces. And, Shann realized, he must present at the moment a satisfactory picture of despondency to any spy. A spy, that was it! Someone or something must have him under observation, or his activities of the day before would not have been so summarily countered. And if there was a spy, then there was his answer to the riddle. To trap the trapper. Such action might be a project beyond his resources, but it was his own counterattack.

  So now he had to play a role. Not only must he search the island for the trace of his spy, but he must do it in such a fashion that his purpose would not be plain to the enemy he suspected. The wolverines could help. Shann arose, allowed his shoulders to droop, slouching to the slope with all the air of a beaten man which he could assume, whistling for Taggi and Togi.

  When they came, his exploration began. Ostensibly he was hunting for lengths of drift or suitable growing saplings to take the place of those he had destroyed under orders. But he kept a careful watch on the animal pair, hoping by their reactions to pick up a clue to any hidden watcher.

  The larger of the two beaches marked the point where the Terrans had first landed and where the shell thing had been killed. The smaller was more of a narrow tongue thrust out into the lagoon, much of it choked with sizable boulders. On earlier visits there Taggi and Togi had poked into the hollows among these with their usual curiosity. But now both animals remained upslope, showing no inclination to descend to the water line.

  Shann caught hold of Taggi's scruff, pulling him along. The wolverine twisted and whined, but he did not fight for freedom as he would have upon scenting Throg. Not that the Terran had ever believed one of those aliens was responsible for the happenings on the island.

  Taggi came down under Shann's urging, but he was plainly ill at ease. And at last he snarled a warning when the man would have drawn him closer to two rocks which met overhead in a crude semblance of an arch. There was a stick of drift protruding from that hollow affording Shann a legitimate excuse to venture closer. He dropped his hold on the wolverines, stooped to gather in the length of wood, and at the same time glanced into the pocket.

  Water lay just beyond, making this a doorway to the lagoon. The sun had not yet penetrated into the shadow, if it ever did. Shann reached for the wood, at the same time drawing his finger across the flat rock which would furnish a steppingstone for anything using that door as an entrance to the island.

  Wet! Which might mean his visitor had recently arrived, or else merely that a splotch of spray had landed there not too long before. But in his mind Shann was convinced that he had found the spy's entrance. Could he turn it into a trap? He added a piece of drift to his bundle and picked up two more before he returned to the cliff ahead.

  A trap.... He revolved in his mind all the traps he knew which could be used here. He already had decided upon the bait—his own work. And if his plans went through—and hope does not die easily—then this time he would not waste his labor either.

  So he went back to the same job he had done the day before, making do with skin strips he had considered second-best before, smoothing, cutting. Only the trap occupied his mind, and close to sunset he knew just what he was going to do and how.

  Though the Terran did not know the nature of the unseen opponent, he thought he could guess two weaknesses which might deliver the other into his hands. First, the enemy was entirely confident of success in this venture. No being who was able to control Shann as completely and ably as had been done the night before would credit any prey with the power to strike back in force.

  Second, such a confident enemy would be unable to resist watching the manipulation of a captive. The Terran was certain that his opponent would be on the scene somewhere when he was led, dreaming, to destroy his work once more.

  He might be wrong on both of those counts, but inwardly he didn't believe so. However, he had to wait until the dark to set up his own answer, one so simple he was certain the enemy would not suspect it at all.

  11. THE WITCH

  There were patches of light in the inner valley marking the phosphorescent plants, some creeping at ground level, others tall as saplings. On other nights Shann had welcomed that wan radiance, but now he lay in as relaxed a position as possible, marking each of those potential betrayers as he tried to counterfeit the attitude of sleep and at the same time plan out his route.

  He had purposely settled in a pool of shadow, the wolverines beside him. And he thought that the bulk of the animal's bodies would cover his own withdrawal when the time came to move. One arm lying limply across his middle was in reality clutching to him an intricate arrangement of small hide straps which he had made by sacrificing most of the remainder of his painfully acquired thongs. The trap must be set in place soon!

  Now that he had charted a path to the crucial point avoiding all light plants, Shann was ready to move. The Terran pressed his hand on Taggi's head in the one imperative command the wolverine was apt to obey—the order to stay where he was.

  Shann sat up and gave the same voiceless instruction to Togi. Then he inched out of the hollow, a worm's progress to that narrow way along the cliff top—the path which anyone or anything coming up from that sea gate on the beach would have to pass in order to witness the shoreline occupied by the half-built outrigger.

  So much of his plan was based upon luck and guesses, but those were all Shann had. And
as he worked at the stretching of his snare, the Terran's heart pounded, and he tensed at every sound out of the night. Having tested all the anchoring of his net, he tugged at a last knot, and then crouched to listen not only with his ears, but with all his strength of mind and body.

  Pound of waves, whistle of wind, the sleepy complaint of some bird.... A regular splashing! One of the fish in the lagoon? Or what he awaited? The Terran retreated as noiselessly as he had come, heading for the hollow where he had bedded down.

  He reached there breathless, his heart pumping, his mouth dry as if he had been racing. Taggi stirred and thrust a nose inquiringly against Shann's arm. But the wolverine made no sound, as if he, too, realized that some menace lay beyond the rim of the valley. Would that other come up the path Shann had trapped? Or had he been wrong? Was the enemy already stalking him from the other beach? The grip of his stunner was slippery in his damp hand; he hated this waiting.

  The canoe ... his work on it had been a careless botching. Better to have the job done right. Why, it was perfectly clear now how he had been mistaken! His whole work plan was wrong; he could see the right way of doing things laid out as clear as a blueprint in his mind. A picture in his mind!

  Shann stood up and both wolverines moved uneasily, though neither made a sound. A picture in his mind! But this time he wasn't asleep; he wasn't dreaming a dream—to be used for his own defeat. Only (that other could not know this) the pressure which had planted the idea of new work to be done in his mind—an idea one part of him accepted as fact—had not taken warning from his move. He was supposed to be under control; the Terran was sure of that. All right, so he would play that part. He must if he would entice the trapper into his trap.

  He holstered his stunner, walked out into the open, paying no heed now to the patches of light through which he must pass on his way to the path his own feet had already worn to the boat beach. As he went, Shann tried to counterfeit what he believed would be the gait of a man under compulsion.

  Now he was on the rim fronting the downslope, fighting against his desire to turn and see for himself if anything had climbed behind. The canoe was all wrong, a bad job which he must make better at once so that in the morning he would be free of this island prison.

  The pressure of that other's will grew stronger. And the Terran read into that the overconfidence which he believed would be part of the enemy's character. The one who was sending him to destroy his own work had no suspicion that the victim was not entirely malleable, ready to be used as he himself would use a knife or a force ax. Shann strode steadily downslope. With a small spurt of fear he knew that in a way that unseen other was right; the pressure was taking over, even though he was awake this time. The Terran tried to will his hand to his stunner, but his fingers fell instead on the hilt of his knife. He drew the blade as panic seethed in his head, chilling him from within. He had underestimated the other's power....

  And that panic flared into open fight, making him forget his careful plans. Now he must wrench free from this control. The knife was moving to slash a hide lashing, directed by his hand, but not his will.

  A soundless gasp, a flash of dismay rocked him, but neither was his gasp nor his dismay. That pressure snapped off; he was free. But the other wasn't! Knife still in fist, Shann turned and ran upslope, his torch in his other hand. He could see a shape now writhing, fighting, outlined against a light bush. And, fearing that the stranger might win free and disappear, the Terran spotlighted the captive in the beam, reckless of Throg or enemy reinforcements.

  The other crouched, plainly startled by the sudden burst of light. Shann stopped abruptly. He had not really built up any mental picture of what he had expected to find in his snare, but this prisoner was as weirdly alien to him as a Throg. The light on the torch was reflected off a skin which glittered as if scaled, glittered with the brilliance of jewels in bands and coils of color spreading from the throat down the chest, spiraling about upper arms, around waist and thighs, as if the stranger wore a treasure house of gems as part of a living body. Except for those patterned loops, coils, and bands, the body had no clothing, though a belt about the slender middle supported a pair of pouches and some odd implements held in loops.

  Roughly the figure was more humanoid than the Throgs. The upper limbs were not too unlike Shann's arms, though the hands had four digits of equal length instead of five. But the features were nonhuman, closer to saurian in contour. It had large eyes, blazing yellow in the dazzle of the flash, with vertical slits of green for pupils. A nose united with the jaw to make a snout, and above the domed forehead a sharp V-point of raised spiky growth extended back and down until behind the shoulder blades it widened and expanded to resemble a pair of wings.

  The captive no longer struggled, but sat quietly in the tangle of the snare Shann had set, watching the Terran steadily as if there were no difficulty in seeing through the brilliance of the beam to the man who held it. And, oddly enough, Shann experienced no repulsion toward its reptilian appearance as he had upon first sighting the beetle-Throg. On impulse he put down his torch on a rock and walked into the light to face squarely the thing out of the sea.

  Still eying Shann, the captive raised one limb and gave an absent-minded tug to the belt it wore. Shann, noting that gesture, was struck by a wild surmise, leading him to study the prisoner more narrowly. Allowing for the alien structure of bone, the nonhuman skin; this creature was delicate, graceful, in its way beautiful, with a fragility of limb which backed up his suspicions. Moved by no pressure from the other, but by his own will and sense of fitness, Shann stooped to cut the control line of his snare.

  The captive continued to watch as Shann sheathed his blade and then held out his hand. Yellow eyes, never blinking since his initial appearance, regarded him, not with any trace of fear or dismay, but with a calm measurement which was curiosity based upon a strong belief in its own superiority. He did not know how he knew, but Shann was certain that the creature out of the sea was still entirely confident, that it made no fight because it did not conceive of any possible danger from him. And again, oddly enough, he was not irritated by this unconscious arrogance; rather he was intrigued and amused.

  "Friends?" Shann used the basic galactic speech devised by Survey and the Free Traders, semantics which depended upon the proper inflection of voice and tone to project meaning when the words were foreign.

  The other made no sound, and the Terran began to wonder if his captive had any audible form of speech. He withdrew a step or two then pulled at the snare, drawing the cords away from the creature's slender ankles. Rolling the thongs into a ball, he tossed the crude net back over his shoulder.

  "Friends?" he repeated again, showing his empty hands, trying to give that one word the proper inflection, hoping the other could read his peaceful intent in his features if not by his speech.

  In one lithe, flowing movement the alien arose. Fully erect, the Warlockian had a frail appearance. Shann, for his breed, was not tall. But the native was still smaller, not more than five feet, that stiff V of head crest just topping Shann's shoulder. Whether any of those fittings at its belt could be a weapon the Terran had no way of telling. However, the other made no move to draw any of them.

  Instead, one of the four-digit hands came up. Shann felt the feather touch of strange finger tips on his chin, across his lips, up his cheek, to at last press firmly on his forehead at a spot just between the eyebrows. What followed was communication of a sort, not in words or in any describable flow of thoughts. There was no feeling of enmity—at least nothing strong enough to be called that. Curiosity, yes, and then a growing doubt, not of the Terran himself, but of the other's preconceived ideas concerning him. Shann was other than the native had judged him, and the stranger was disturbed, that self-confidence a little ruffled. And also Shann was right in his guess. He smiled, his amusement growing—not aimed at his companion on this cliff top, but at himself. For he was dealing with a woman, a very young woman, and someone as fully feminine in he
r way as any human girl could be.

  "Friends?" he asked for the third time.

  But the other still exuded a wariness, a wariness mixed with surprise. And the tenuous message which passed between them then astounded Shann. To this Warlockian out of the night he was not following the proper pattern of male behaviour at all; he should have been in awe of the other merely because of her sex. A diffidence rather than an assumption of equality should have colored his response, judged by her standards. At first, he caught a flash of anger at this preposterous attitude of his; then her curiosity won, but there was still no reply to his question.

  The finger tips no longer made contact between them. Stepping back, her hands now reached for one of the pouches at her belt. Shann watched that movement carefully. And because he did not trust her too far, he whistled.

  Her head came up. She might be dumb, but plainly she was not deaf. And she gazed down into the hollow as the wolverines answered his summons with growls. Her profile reminded Shann of something for an instant; but it should have been golden-yellow instead of silver with two jeweled patterns ringing the snout. Yes, that small plaque he had seen in the cabin of one of the ship's officers. A very old Terran legend—"Dragon," the officer had named the creature. Only that one had possessed a serpent's body, a lizard's legs and wings.

  Shann gave a sudden start, aware his thoughts had made him careless, or had she in some way led him into that bypath of memory for her own purposes? Because now she held some object in the curve of her curled fingers, regarding him with those unblinking yellow eyes. Eyes ... eyes.... Shann dimly heard the alarm cry of the wolverines. He tried to snap draw his stunner, but it was too late.

  There was a haze about him hiding the rocks, the island valley with its radiant plants, the night sky, the bright beam of the torch. Now he moved through that haze as one walks through a dream approaching nightmare, striding with an effort as if wading through a deterring flood. Sound, sight—one after another those senses were taken from him. Desperately Shann held to one thing, his own sense of identity. He was Shann Lantee, Terran breed, out of Tyr, of the Survey Service. Some part of him repeated those facts with vast urgency against an almost overwhelming force which strove to defeat that awareness of self, making him nothing but a tool—or a weapon—for another's use.
