He tried to force open the studs across his chest, but they would not yield to the slight pressure which was all his seared fingers could exert, and when he pulled at the fabric, he was unable to tear it. So, still wearing the livery of the off-world men, Ross continued on his way, hardly caring where he went or how. The mud plastered on him by his frequent falls was some protection against the swarm of insect life his passing stirred into attack. However, he was able to endure a swollen face and slitted eyes, being far more conscious of the wrenching feeling within him than the misery of his body.

  The character of the marsh began to change once more. The river was splitting into a dozen smaller streams, shaping out fanlike. Looking down at this from one of the marsh hillocks, Ross knew a faint surge of relief. Such a place had been on the map Ashe had made them memorize. He was close to the sea at last, and for the moment that was enough.

  A salt-sharpened wind cut at him with the force of a fist in the face. In the absence of sunlight the leaden clouds overhead set a winterlike gloom across the countryside. To the constant sound of birdcalls Ross tramped heavily through small pools, beating a path through tangles of marsh grass. He stole eggs from nests, sucking his nourishment eagerly with no dislike for the fishy flavor, and drinking from stagnant, brackish ponds.

  Suddenly Ross halted, at first thinking that the continuous roll of sound he heard was thunder. Yet the clouds overhead were massed no more than before and there was no sign of lightning. Continuing on, he realized that the mysterious sound was the pounding of surf—he was near the sea!

  Willing his body to run, he weaved forward at a reeling trot, pitting all his energy against the incessant pull from behind. His feet skidded out of marsh mud into sand. Ahead of him were dark rocks surrounded by the white lace of spray.

  Ross headed straight toward that spray until he stood knee-deep in the curling, foam-edged water and felt its tug on his body almost as strong as that other tug upon his mind. He knelt, letting the salt water sting to life every cut, every burn, sputtering as it filled his mouth and nostrils, washing from him the slime of the bog lands. It was cold and bitter, but it was the sea! He had made it!

  Ross Murdock staggered back and sat down suddenly in the sand. Glancing about, he saw that his refuge was a rough triangle between two of the small river arms, littered with the debris of the spring floods which had grounded here after rejection by the sea. Although there was plenty of material for a fire, he had no means of kindling a flame, having lost the flint all Beaker traders carried for such a purpose.

  This was the sea, and against all odds he had reached it. He lay back, his self-confidence restored to the point where he dared once more to consider the future. He watched the swooping flight of gulls drawing patterns under the clouds above. For the moment he wanted nothing more than to lie here and rest.

  But he did not surrender to this first demand of his over-driven body for long. Hungry and cold, sure that a storm was coming, he knew he had to build a fire—a fire on shore could provide him with the means of signaling the sub. Hardly knowing why—because one part of the coastline was as good as another—Ross began to walk again, threading a path in and out among the rocky outcrops.

  So he found it, a hollow between two such windbreaks within which was a blackened circle of small stones holding charred wood, with some empty shells piled near-by. Here was unmistakable evidence of a camp! Ross plunged forward, thrusting a hand impetuously into the black mass of the dead fire. To his astonishment, he touched warmth!

  Hardly daring to disturb those precious bits of charcoal, he dug around them, then carefully blew into what appeared to be dead ashes. There was an answering glow! He could not have just imagined it.

  From a pile of wood that had been left behind, Ross snatched a small twig, poking it at the coal after he had rubbed it into a brush on the rough rock. He watched, all one ache of hope. The twig caught!

  With his stiff fingers so clumsy, he had to be very careful, but Ross had learned patience in a hard school. Bit by bit he fed that tiny blaze until he had a real fire. Then, leaning back against the rock, he watched it.

  It was now obvious that the placement of the original fire had been chosen with care, for the outcrops gave it wind shelter. They also provided a dark backdrop, partially hiding the flames on the landward side but undoubtedly making them more visible from the sea. The site seemed just right for a signal fire—but to what?

  Ross's hands shook slightly as he fed the blaze. It was only too clear why anyone would make a signal on this shore. McNeil—or perhaps both he and Ashe—had survived the breakup of the raft, after all. They had reached this point—abandoned no earlier than this morning, judging by the life remaining in the coals—and put up the signal. Then, just as arranged, they had been collected by the sub, by now on its way back to the hidden North American post. There was no hope of any pickup for him now. Just as he had believed them dead after he had found that rag on the sapling, so they must have thought him finished after his fall in the river. He was just a few hours too late!

  Ross folded his arms across his hunched knees and rested his head on them. There was no possible way he could ever reach the post or his own kind—ever again. Thousands of miles lay between him and the temporary installation in this time.

  He was so sunk in his own complete despair that he was long unaware of finally being free of the pressure to turn back which had so long haunted him. But as he roused to feed the fire he got to wondering. Had those who hunted him given up the chase? Since he had lost his own race with time, he did not really care. What did it matter?

  The pile of wood was getting low, but he decided that did not matter either. Even so, Ross got to his feet, moving over to the drifts of storm wrack to gather more. Why should he stay here by a useless beacon? But somehow he could not force himself to move on, as futile as his vigil seemed.

  Dragging the sun-dried, bleached limbs of long-dead trees to his half shelter, he piled them up, working until he laughed at the barricade he had built. "A siege!" For the first time in days he spoke aloud. "I might be ready for a siege...." He pulled over another branch, added it to his pile, and kneeled down once more by the flames.

  There were fisherfolk to be found along this coast, and tomorrow when he was rested he would strike south and try to find one of their primitive villages. Traders would be coming into this territory now that the Red-inspired raiders were gone. If he could contact them....

  But that spark of interest in the future died almost as soon as it was born. To be a Beaker trader as an agent for the project was one thing, to live the role for the rest of his life was something else.

  Ross stood by his fire, staring out to sea for a sign he knew he would never see again as long as he lived. Then, as if a spear had struck between his shoulder blades, he was attacked.

  The blow was not physical, but came instead as a tearing, red pain in his head, a pressure so terrible he could not move. He knew instantly that behind him now lurked the ultimate danger.

  CHAPTER 18

  Ross fought to break that hold, to turn his head, to face the peril which crept upon him now. Unlike anything he had ever met before in his short lifetime, it could only have come from some alien source. This strange encounter was a battle of will against will! The same rebellion against authority which had ruled his boyhood, which had pushed him into the orbit of the project, stiffened him to meet this attack.

  He was going to turn his head; he was going to see who stood there. He was! Inch by inch, Ross's head came around, though sweat stung his seared and bitten flesh, and every breath was an effort. He caught a half glimpse of the beach behind the rocks, and the stretch of sand was empty. Overhead the birds were gone—as if they had never existed. Or, as if they had been swept away by some impatient fighter, who wanted no distractions from the purpose at hand.

  Having successfully turned his head, Ross decided to turn his body. His left hand went out, slowly, as if it moved some great weight. His palm
gritted painfully on the rock and he savored that pain, for it pierced through the dead blanket of compulsion that was being used against him. Deliberately he ground his blistered skin against the stone, concentrating on the sharp torment in his hand as the agony shot up his arm. While he focused his attention on the physical pain, he could feel the pressure against him weaken. Summoning all his strength, Ross swung around in a movement which was only a shadow of his former feline grace.

  The beach was still empty, except for the piles of driftwood, the rocks, and the other things he had originally found there. Yet he knew that something was waiting to pounce. Having discovered that for him pain was a defense weapon, he had that one resource. If they took him, it would be after besting him in a fight.

  Even as he made this decision, Ross was conscious of a curious weakening of the force bent upon him. It was as if his opponents had been surprised, either at his simple actions of the past few seconds or at his determination. Ross leaped upon that surprise, adding it to his stock of unseen weapons.

  He leaned forward, still grinding his torn hand against the rock as a steadying influence, took up a length of dried wood, and thrust its end into the fire. Having once used fire to save himself, he was ready and willing to do it again, although at the same time, another part of him shrank from what he intended.

  Holding his improvised torch breast-high, Ross stared across it, searching the land for the faintest sign of his enemies. In spite of the fire and the light he held before him, the dusk prevented him from seeing too far. Behind him the crash of the surf could have covered the noise of a marching army.

  "Come and get me!"

  He whirled his brand into bursting life and then hurled it straight into the drift among the dunes. He was grabbing for a second brand almost before the blazing head of the first had fallen into the twisted, bleached roots of a dead tree.

  He stood tense, a second torch now kindled in his hand. The sharp vise of another's will which had nipped him so tightly a moment ago was easing, slowly disappearing as water might trickle away. Yet he could not believe that this small act of defiance had so daunted his unseen opponent as to make him give up the struggle this easily. It was more likely the pause of a wrestler seeking for a deadlier grip.

  The brand in his hand—Ross's second line of defense—was a weapon he was loath to use, but would use if he were forced to it. He kept his hand mercilessly flat against the rock as a reminder and a spur.

  Fire twisted and crackled among the driftwood where the first torch had lodged, providing a flickering light yards from where he stood. He was grateful for it in the gloom of the gathering storm. If they would only come to open war before the rain struck....

  Ross sheltered his torch with his body as spray, driven inward from the sea, spattered his shoulders and his back. If it rained, he would lose what small advantage the fire gave him, but then he would find some other way to meet them. They would neither break him nor take him, even if he had to wade into the sea and swim out into the lash of the cold northern waves until he could not move his tired limbs any longer.

  Once again that steel-edge will struck at Ross, probing his stubbornness, assaulting his mind. He whirled the torch, brought the scorching breath of the flame across the hand resting on the rock. Unable to control his own cry of protest, he was not sure he had the fortitude to repeat such an act.

  He had won again! The pressure had fallen away in a flick, almost as if some current had been snapped off. Through the red curtain of his torment Ross sensed a surprise and disbelief. He was unaware that in this queer duel he was using both a power of will and a depth of perception he had never known he possessed. Because of his daring, he had shaken his opponents as no physical attack could have affected them.

  "Come and get me!" He shouted again at the barren shoreline where the fire ate at the drift and nothing stirred, yet something very much alive and conscious lay hidden. This time there was more than simple challenge in Ross's demand—there was a note of triumph.

  The spray whipped by him, striking at his fire, at the brand he held. Let the sea water put both out! He would find another way of fighting. He was certain of that, and he sensed that those out there knew it too and were troubled.

  The fire was being driven by the wind along the crisscross lines of bone-white wood left high on the beach, forming a wall of flame between him and the interior, not, however, an insurmountable barrier to whatever lurked there.

  Again Ross leaned against the rock, studying the length of beach. Had he been wrong in thinking that they were within the range of his voice? The power they had used might carry over a greater distance.

  "Yahhhh—" Instead of a demand, he now voiced a taunting cry, screaming his defiance. Some wild madness had been transmitted to him by the winds, the roaring sea, his own pain. Ready to face the worst they could send against him, he tried to hurl that thought back at them as they had struck with their united will at him. No answer came to his challenge, no rise to counter-attack.

  Moving away from the rock, Ross began to walk forward toward the burning drift, his torch ready in his hand. "I am here!" he shouted into the wind. "Come out—face me!"

  It was then that he saw those who had tracked him. Two tall thin figures, wearing dark clothes, were standing quietly watching him, their eyes dark holes in the white ovals of their faces.

  Ross halted. Though they were separated by yards of sand and rock and a burning barrier, he could feel the force they wielded. The nature of that force had changed, however. Once it had struck with a vigorous spear point; now it formed a shield of protection. Ross could not break through that shield, and they dared not drop it. A stalemate existed between them in this strange battle, the like of which Ross's world had not known before.

  He watched those expressionless white faces, trying to find some reply to the deadlock. There flashed into his mind the certainty that while he lived and moved, and they lived and moved, this struggle, this unending pursuit, would continue. For some mysterious reason they wanted to have him under their control, but that was never going to happen if they all had to remain here on this strip of water-washed sand until they starved to death! Ross tried to drive that thought across to them.

  "Murrrrdock!" That croaking cry borne out of the sea by the wind might almost have come from the bill of a sea bird.

  "Murrrrdock!"

  Ross spun around. Visibility had been drastically curtailed by the lowering clouds and the dashing spray, but he could see a round dark thing bobbing on the waves. The sub? A raft?

  Sensing a movement behind him, Ross wheeled about as one of the alien figures leaped the blazing drift, heedless of the flames, and ran light-footedly toward him in what could only be an all-out attempt at capture. The man had ready a weapon like the one that had felled Foscar. Ross threw himself at his opponent in a reckless dive, falling on him with a smashing impact.

  In Ross's grasp the alien's body was fragile, but he moved fluidly as Murdock fought to break his grip on the hand weapon and pin him to the sand. Ross was too intent upon his own part of the struggle to heed the sounds of a shot over his head and a thin, wailing cry. He slammed his opponent's hand against a stone, and the white face, inches away from his own, twisted silently with pain.

  Fumbling for a better hold, Ross was sent rolling. He came down on his left hand with a force which brought tears to his eyes and stopped him just long enough for the other to regain his feet.

  The blue-suited man sprinted back to the body of his fellow where it lay by the drift. He slung his unconscious comrade over the barrier with more ease than Ross would have believed possible and vaulted the barrier after him. Ross, half crouched on the sand, felt unusually light and empty. The strange tie which had drawn and held him to the strangers had been broken.

  "Murdock!"

  A rubber raft rode in on the waves, two men aboard it. Ross got up, pulling at the studs of his suit with his right hand. He could believe in what he saw now—the sub had not left, afte
r all. The two men running toward him through the dusk were of his own kind.

  "Murdock!"

  It did not seem at all strange that Kelgarries reached him first. Ross, caught up in this dream, appealed to the major for aid with the studs. If the strangers from the ship did trace him by the suit, they were not going to follow the sub back to the post and serve the project as they had the Reds.

  "Got—to—get—this—off—" He pulled the words out one by one, tugging frantically at the stubborn studs. "They can trace this and follow us—"

  Kelgarries needed no better explanation. Ripping loose the fastenings, he pulled the clinging fabric from Ross, sending him reeling with pain as he pulled the left sleeve down the younger man's arm.

  The wind and spray were ice on his body as they dragged him down to the raft, bundling him aboard. He did not at all remember their arrival on board the sub. He was lying in the vibrating heart of the undersea ship when he opened his eyes to see Kelgarries regarding him intently. Ashe, a coat of bandage about his shoulder and chest, lay on a neighboring bunk. McNeil stood watching a medical corpsman lay out supplies.

  "He needs a shot," the medic was saying as Ross blinked at the major.

  "You left the suit—back there?" Ross demanded.

  "We did. What's this about them tracing you by it? Who was tracing you?"

  "Men from the space ship. That's the only way they could have trailed me down the river." He was finding it difficult to talk, and the protesting medic kept waving a needle in his direction, but somehow in bursts of half-finished sentences Ross got out his story—Foscar's death, his own escape from the chief's funeral pyre, and the weird duel of wills back on the beach. Even as he poured it out he thought how unlikely most of it must sound. Yet Kelgarries appeared to accept every word, and there was no expression of disbelief on Ashe's face.
