What was so important about this island that Thorvald _had_ to make a landing here? The officer's stories of a native race which they might turn against the Throgs to their own advantage was thin, very thin indeed. Especially now, as Shann weighed an unsupported theory against that ache in his shoulders, the possibility of being marooned on the inhospitable shore ahead, against the fifty probable dangers he could total up with very little expenditure of effort. A small nagging doubt of Thorvald's obsession began to grow in his mind. How could Shann even be sure that that carved disk and Thorvald's hokus-pokus with it had been on the level? On the other hand what motive would the officer have for trying such an act just to impress Shann?
The beach at last! As they headed the canoe in that direction the wolverines nearly brought disaster on them. The animals' restlessness became acute as they sighted and scented the shore and knew that they were close. Taggi reared, plunged over the side of the craft, and Shann had just time to fling his weight in the opposite direction as a counterbalance when Togi followed. They splashed shoreward while Thorvald swore fluently and Shann grabbed to save the precious supply bag. In a shower of gravel the animals made land and humped well up on the strand before pausing to shake themselves and splatter far and wide the burden of moisture transported by their shaggy fur.
Ashore, the canoe became a clumsy burden and, light as the craft was, both of the men sweated to get it up on the beach without snagging the outrigger against stones and brush. With the thought of a Throg patrol in mind they worked swiftly to cover it.
Taggi raised an egg-patterned snout from a hollow and licked at the stippling of greenish yolk matting his fur. The wolverines had wasted no time in sampling the contents of a wealth of nesting places beginning just above the high-water mark, cupping two to four tough-shelled eggs in each. Treading a path among those clutches, the Terrans climbed a red-earthed slope toward the interior of the island.
They found water, not the clear running of a mountain spring, but a stalish pool in a stone-walled depression on the crest of a rise, filled by the bounty of the rain. The warm liquid was brackish, but satisfied in part their thirst, and they drank eagerly.
The outer cliff wall of the island was just that, a wall, for there was an inner slope to match the outer. And at the bottom of it a showing of purple-green foliage where plants and stunted trees fought for living space. But there was nothing else, though they quartered that growing section with the care of men trying to locate an enemy outpost.
That night they camped in the hollow, roasted eggs in a fire, and ate the fishy-tasting contents because it was food, not because they relished what they swallowed. Tonight no cloud bank hung overhead. A man, gazing up, could see the stars. The stars and other things, for over the distant shore of the mainland they sighted the cruising lights of a Throg ship and waited tensely for that circle of small sparkling points to swing out toward their own hiding hole.
"They haven't given up," Shann stated what was obvious to them both.
"The settler transport," Thorvald reminded him. "If they do not take a prisoner to talk her in and allay suspicion, then--" he snapped his fingers--"the Patrol will be on their tails, but quick!"
So just by keeping out of Throg range, they were, in a way, still fighting. Shann settled back, his tender shoulders resting against a tree hole. He tried to count the number of days and nights lying behind him now since that early morning when he had watched the Terran camp die under the aliens' weapons. But one day faded into another so that he could remember only action parts clearly--the attack on the grounded scoutship, the sortie they had made in turn on the occupied camp, the dust storm on the river, the escape from the Throg ship in the mountain crevice, and their meeting with the hound. Then that storm which had driven them to seek cover after their curious experience with the disk. And now this day when they had safely reached the island.
"Why this island?" he asked suddenly.
"That carved piece was found here on the edge of this valley," Thorvald returned matter-of-factly.
"But today we found nothing at all----"
"Yet this island supplies us with a starting point."
A starting point for what? A detailed search of all the islands, great and small, in the chain? And how did they dare continue to paddle openly from one to the next with the Throgs sweeping the skies? They would have provided an excellent target today as they combed that reef for an hour or more. Wearily, Shann spread out his hands in the very faint light of their tiny fire, poked with a finger tip at smarting points which would have been blisters had those hands not known a toughening process in the past. More paddling tomorrow? But that was tomorrow, and at least they need not worry tonight about any Throg attack once they had doused the fire, an action which was now being methodically attended to by Thorvald. Shann pushed down on the bed of leaves he had heaped together. The night was quiet. He could hear only the murmur of the sea, a lulling croon of sound to make one sleep deep, perhaps dreamlessly.
Sun struck down, making a dazzle about him. Shann turned over drowsily in that welcome heat, stretching a little as might a cat at ease. Then he really awoke under the press of memory, and the need for alertness rode him once more. Beaten-down grass, the burnt-out embers of last night's fire were beside him. But of Thorvald and the wolverines there were no signs.
Not only did he now lie alone, but he was possessed by the feeling that he had not been deserted only momentarily, that Taggi, Togi and the Survey officer were indeed gone. Shann sat up, got to his feet, breathing faster, a prickle of uneasiness spreading in him, bringing him to that inner slope, up it to the crest from which he could see that beach where last night they had concealed the canoe.
Those lengths of brush and tufts of grass they had used for a screen were strewn about as if tossed in haste. And not too long before....
For the canoe was out in the calm waters within the reef, the paddle blade wielded by its occupant flashing brightly in the sun. On the shingle below, the wolverines prowled back and forth, whining in bewilderment.
"Thorvald----!"
Shann put the full force of his lungs into that hail, hearing the name ring from one of the small peaks at his back. But the man in the boat did not turn his head; there was no change in the speed of that paddle dip.
Shann leaped down the outer slope to the beach, skidding the last few feet, saving himself from going headfirst into the water only by a painful wrench of his body.
"Thorvald!" He tried calling again. But that head, bright under the sun did not turn; there was no answer. Shann tore at his clothes and kicked off his boots.
He did not think of the possibility of lurking sea monsters as he plunged into the water, swam for the canoe edging along the reef, plainly bound for the sea gate to the southwest. Shann was not a powerful swimmer. His first impetus gave him a good start, but after that he had to fight for each foot he gained, and the fear grew in him that the other would reach the reef passage before he could catch up. He wasted no more time trying to hail Thorvald, putting all his breath and energy into the effort of overtaking the craft.
And he almost made it, his hand actually slipping along the log which furnished the balancing outrigger. As his fingers tightened on the slimy wood he looked up, and loosed that hold again in time perhaps to save his life.
For when he ducked to let the water cover his head in an impromptu half dive, Shann carried with him a vivid picture, a picture so astounding that he was a little dazed.
Thorvald had stopped paddling at last, because that paddle had to be put to another use. Had Shann not released his hold on the log and gone under water, that crudely fashioned piece of wood might, have broken his skull. He saw only too clearly the paddle raised in both hands as an ugly weapon, and Thorvald's face, convulsed in a spasm of rage which made it as inhuman as a Throg's.
Sputtering and choking, Shann fought up to the air once more. The paddle was back at the task for which it had been carved, the canoe was underway again, its oc
cupant paying no more attention to what lay behind than if he _had_ successfully disposed of the man in the water. To follow would be only to invite another attack, and Shann might not be so lucky next time. He was not good enough a swimmer to try any tricks such as oversetting the canoe, not when Thorvald was an expert who could easily finish off a fumbling opponent.
Shann swam wearily to shore where the wolverines waited, unable yet to make sense of that attack in the lagoon. What had happened to Thorvald? What motive had led the other to leave Shann and the animals on this island, the island Thorvald had called a starting point in his search for the natives of Warlock? Or had every bit of that tall tale been invented by the Survey officer for some obscure purpose of his own, certainly no sane purpose? Against that logic Shann could only set the carved disk, and he had only Thorvald's word that that had been discovered here.
He dragged himself out of the water on his hands and knees and lay, winded and gasping. Taggi came to lick his face, nuzzle him, making a small, bewildered whimpering. While above, the leather-headed birds called and swooped, fearful and angry for their disturbed nesting place. The Terran retched, coughed up water, and then sat up to look around.
The spread of lagoon was bare. Thorvald must have rounded the south point of land and be very close to the reef passage, perhaps through it by now. Not stopping for his clothes, Shann started up the slope, crawling part of the way on his hands and knees.
He reached the crest again and got to his feet. The sun made an eye-dazzling glitter of the waves. But under the shade of his hands Shann saw the canoe again, beyond the reef, heading on out along the island chain, not back to shore as he had expected. Thorvald was still on the hunt, but for what? A reality which existed, or a dream in his own disturbed brain?
Shann sat down. He was very hungry, for that adventure in the lagoon had sapped his strength. And he was a prisoner along with the wolverines, a prisoner on an island which was half the size of the valley which held the Survey camp. As far as he knew, his only supply of drinkable water was that tank of evil-smelling rain which would be speedily evaporated by a sun such as the one now beating down on him. And between him and the shore was the sea, a sea which harbored such creatures as the fork-tail he had watched die.
Thorvald was still steadily on course, not to the next island in the chain, a small, bare knob, but to the one beyond that. He could have been hurrying to a meeting. Where and with what?
Shann got to his feet, started down to the beach once more, sure now that the officer had no intention of returning, that he was again on his own with only his wits and strength to keep him alive--alive and somehow free of this water-washed prison.
10. A TRAP FOR A TRAPPER
Shann took up the piece of soft chalklike stone he had found and drew another short white mark on the rust-red of a boulder well above tide level. That made three such marks, three days since Thorvald had marooned him. And he was no nearer the shore now than he had been on that first morning! He sat where he was by the boulder, aware that he should be up, trying to climb to the less accessible nests of the sea birds. The prisoners, man and wolverines, had cleaned out all those they had discovered on beach and cliffs. But at the thought of more eggs, Shann's stomach knotted in pain and he began to retch.
There had been no sign of Thorvald since Shann had watched him steer between the two westward islands. And the younger Terran's faint hope that the officer would return had died. On the shore a few feet away lay his own pitiful attempt to solve the problem of escape.
The force ax had vanished with Thorvald, along with all the rest of the meager supplies which had been the officer's original contribution to their joint equipment. Shann had used his knife on brush and small trees, trying to put together some kind of a raft. But he had not been able to discover here any of those vines necessary for binding, and his best efforts had all come to grief when he tried them in a lagoon launching. So far he had achieved no form of raft which would keep him afloat longer than five minutes, let alone support three of them as far as the next island.
Shann pulled listlessly at the framework of his latest try, fully disheartened. He tried not to think of the unescapable fact that the water in the rain tank had sunk to only an inch or so of muddy scum. Last night he had dug in the heart of the interior valley where the rankness of the vegetation was a promise of moisture, to uncover damp clay and then a brackish ooze. Far too little to satisfy both him and the animals.
There were surely fish somewhere in the lagoon. Shann wondered if the raw flesh of sea dwellers could supply the water they needed. But lacking net, line, or hooks, how did one fish? Yesterday, using his stunner, he had brought down a bird, to discover the carcass so rank even the wolverines, never dainty eaters, refused to gnaw it.
The animals prowled the two beaches, and Shann guessed they hunted shell dwellers, for at times they dug energetically in the gravel. Togi was busied in this way now, the sand flowing from under her pumping legs, her claws raking in good earnest.
And it was Togi's excavation which brought Shann a first ray of hope. Her excitement was so marked that he believed she was in quest of some worthwhile game and he moved across to inspect the pit. A patch of brown, which had been skimmed bare by one raking paw, made him shout.
Taggi shambled downslope, going to work beside his mate with an eagerness as open as hers. Shann hovered at the edge of the pit they were rapidly enlarging. The brown patch was larger, disclosing itself as a hump doming up from the gravel. The Terran did not need to run his hands over that rough surface to recognize the nature of the find. This was another shell such as had come floating in after the storm to form the raw material of their canoe.
However, as fast as the wolverines dug, they did not appear to make correspondingly swift headway in uncovering their find as might reasonably be expected. In fact, a witness could guess that the shell was sinking at a pace only a fraction slower than the burrowers were using to free it. Intrigued by that, Shann went back to the waterline, secured one of the lengths he had been trying to weave into his failures, and returned to use it as a makeshift shovel.
Now, with three of them at the digging, the brown hump was uncovered, and Shann pried down around its edge, trying to lever it up and over. To his amazement, his tool was caught and held, nearly jerked from his hands. To his retaliating tug the obstruction below-ground gave way, and the Terran sprawled back, the length of wood coming clear, to show the other end smashed and splintered as if it had been caught between mashing gears.
For the first time he understood that they were dealing not with an empty shell casing buried by drift under this small beach, but with a shell still inhabited by the Warlockian to whom it was a natural covering, and that that inhabitant would fight to continue ownership. A moment's examination of that splintered wood also suggested that the shell's present wearer appeared well able to defend itself.
Shann attempted to call off the wolverines, but they were out of control now, digging frantically to get at this new prey. And he knew that if he pulled them away by force, they were apt to turn those punishing claws and snapping jaws on him.
It was for their protection that he returned to digging, though he no longer tried to pry up the shell. Taggi leaped to the top of that dome, sweeping paws downward to clear its surface, while Togi prowled around its circumference, pausing now and then to send dirt and gravel spattering, but treading warily as might one alert for a sudden attack.
They had the creature almost clear now, though the shell still rested firmly on the ground, and they had no notion of what it might protect. It was smaller, perhaps two thirds the size of the one which Thorvald had fashioned into a seagoing craft. But it could provide them with transportation to the mainland if Shann was able to repeat the feat of turning it into an outrigger canoe.
Taggi joined his mate on the ground and both wolverines padded about the dome, obviously baffled. Now and then they assaulted the shell with a testing paw. Claws raked and did not leave any mark
s but shallow scratches. They could continue that forever, as far as Shann could see, without solving the problem in the least.
He sat back on his heels and studied the scene in detail. The excavation holding the shelled creature was some three yards above the high-water mark, with a few more feet separating that from the point where lazy waves now washed the finer sand. Shann watched the slow inward slip of those waves with growing interest. Where their combined efforts had failed to win this odd battle, perhaps the sea itself could now be pressed into service.
