The sill was wide, at least a twenty-four-inch span between the inner and outer surface of the tower. Travis sat there for a minute, reluctant to enter. Near the end of his dangling scarf-rope the two coyotes lay on the pavement, their heads up, their tongues lolling from their mouths, their expressions ones of detached interest.
Perhaps it was the width of the outer wall that subdued the amount of light in the room. The chamber was circular, and directly opposite him was a second window, the lowest of the matching diamond pattern. He took the four-foot drop from the sill to the floor but lingered in the light as he surveyed every inch of the room. There were no furnishings at all, but in the very center sank a well of darkness. A smooth pillar, glowing faintly, rose from its core. Travis’ adjusting eyes noted how the light came in small ripples—green and purple, over a foundation shade of dark blue.
The pillar seemed rooted below and it extended up through a similar opening in the ceiling, providing the only possible exit up or down, save for climbing from window to window outside. Travis moved slowly to the well. Underfoot was a smooth surface overlaid with a velvet carpet of dust which arose in languid puffs as he walked. Here and there he sighted prints in the dust, strange triangular wedges which he thought might possibly have been made by the claws of birds. But there were no other footprints. This tower had been undisturbed for a long, long time.
He came to the well and looked down. There was dark there, dark in which the pulsations of light from the pillar shone the stronger. But that glow did not extend beyond the edge of the well through which the thick rod threaded. Even by close examination he could detect no break in the smooth surface of the pillar, nothing remotely resembling hand- or footholds. If it did serve the purpose of a staircase, there were no treads.
At last Travis put out his hand to touch the surface of the pillar. And then he jerked back—to no effect. There was no breaking contact between his fingers and an unknown material which had the sleekness of polished metal but—and the thought made him slightly queasy—the warmth and very slight give of flesh!
He summoned all his strength to pull free and could not. Not only did that hold grip him, but his other hand and arm were being drawn to join the first! Inside Travis primitive fears awoke full force, and he threw back his head, voicing a cry of panic as wild as that of a hunting beast.
An instant later, his left palm was as tight a prisoner as his right. And with both hands so held, his whole body was suddenly snapped forward, off the safe foundation of the floor, tight to the pillar.
In this position he was sucked down into the well. And while unable to free himself from the pillar, he did slip along its length easily enough. Travis shut his eyes in an involuntary protest against this weird form of capture, and a shiver ran through his body as he continued to descend.
After the first shock had subsided the Apache realized that he was not truly falling at all. Had the pillar been horizontal instead of vertical, he would have gauged its speed that of a walk. He passed through two more room enclosures; he must already be below the level of the valley floor outside. And he was still a prisoner of the pillar, now in total darkness.
His feet came down against a level surface, and he guessed he must have reached the end. Again he pulled back, arching his shoulders in a final desperate attempt at escape, and stumbled away as he was released.
He came up sideways against a wall and stood there panting. The light, which might have come from the pillar but which seemed more a part of the very air, was bright enough to reveal that he was in a corridor running into greater dark both right and left.
Travis took two strides back to the pillar, fitted his palms once again to its surface, with no result. This time his flesh did not adhere and there was no possible way for him to climb that slick pole. He could only hope that at some point the corridor would give him access to the surface. But which way to go—?
At last he chose the right-hand path and started along it, pausing every few steps to listen. But there was no sound except the soft pad of his own feet. The air was fresh enough, and he thought he could detect a faint current coming toward him from some point ahead—perhaps an exit.
Instead, he came into a room and a small gasp of astonishment was wrung out of him. The walls were blank, covered with the same ripples of blue-purple-green light which colored the pillar. Just before him was a table and behind it a bench, both carved from the native yellow-red mountain rock. And there was no exit except the doorway in which he now stood.
Travis walked to the bench. Immovable, it was placed so that whoever sat there must face the opposite wall of the chamber with the table before him. And on the table was an object Travis recognized immediately from his voyage in the alien star ship, one of the tape-readers through which the involuntary explorers had learned what little they knew of the older galactic civilization.
A reader—and beside it a box of tapes. Travis touched the edge of that box gingerly, half expecting it to crumble into nothingness. This was a place long deserted. Stone table, bench, the towers could survive through centuries of abandonment, but these other objects . . .
The substance of the reader was firm under the film of dust; there was less dust here than had been in the upper tower chamber. Hardly knowing why, Travis threw one leg over the bench and sat down behind the table, the reader before him, the box of tapes just beyond his hand.
He surveyed the walls and then looked away hurriedly. The rippling colors caught at his eyes. He had a feeling that if he watched that ebb and flow too long, he would be captured in some subtle web of enchantment just as the Russians’ machine had caught and held the Tatars. He turned his attention to the reader. It was, he believed, much like the one they had used on the ship.
This room, table, bench, had all been designed with a set purpose. And that purpose—Travis’ fingers rested on the box of tapes he could not yet bring himself to open—that purpose was to use the reader, he would swear to that. Tapes so left must have had a great importance for those who left them. It was as if the whole valley was a trap to channel a stranger into this underground chamber.
Travis snapped open the box, fed the first disk into the reader, and applied his eyes to the vision tube at its apex.
The rippling walls looked just the same when he looked up once more, but the cramp in his muscles told Travis that time had passed—perhaps hours instead of minutes—since he had taken out the first disk. He cupped his hands over his eyes and tried to think clearly. There had been sheets of meaningless symbol writing, but also there had been many clear, three-dimensional pictures, accompanied by a singsong commentary in an alien tongue, seemingly voiced out of thin air. He had been stuffed with ragged bits and patches of information, to be connected only by guesses, and some wild guesses, too. But this much he did know—these towers had been built by the bald spacemen, and they were highly important to that vanished stellar civilization. The information in this room, as disjointed as it had been for him, led to a treasure trove on Topaz greater than he had dreamed.
Travis swayed on the bench. To know so much and yet so little! If Ashe were only here, or some other of the project technicians! A treasure such as Pandora’s box had been, peril for one who opened it and did not understand. The Apache studied the three walls of blue-purple-green in turn and with new attention. There were ways through those walls; he was fairly sure he could unlock at least one of them. But not now—certainly not now!
And there was another thing he knew: The Russians must not find this. Such a discovery on their part would not only mean the end of his own people on Topaz, but the end of Earth as well. This place might hold new and alien knowledge that could destroy whole nations at a time!
If he could—much as his archaeologist’s training would argue against it—he would blot out this whole valley above and below ground. But while the Russians might possess a means of such destruction, the Apaches did not. No, he and his people must prevent its discovery by the enemy by doing what he had seen as necessary from the first—wiping out the Russian leaders! And that must be done before they chanced upon the tower!
