was then that he began to question his assumption that the prisoner was one of them.
Over and over again in his mind he tried to repicture the capture as he had witnessed it from the building just too far away and at slightly the wrong angle for a clear view. He would swear that the body he had seen tumble into the flood had not been furred, that much he was sure of. But clothing, yes, there had been clothing. Not—his mind suddenly produced that one scrap of memory—not the bandage windings of the aliens. And hadn’t the skin been fairer? Was there another race on this continent, one they had not been told about?
When they at last reached the shore of the western continent and finally the home city of the aliens, the globe headed back to its berth, not in the roof cradle from which it had arisen, but sinking into the building itself. Raf brought the flitter down on a roof as close to the main holding of the painted people as he could get. None of the aliens came near them. It seemed that they were to be ignored. Hobart paced along the flat roof, and Soriki sat in the flyer, nursing his com, intent upon the slender thread of beam which tied them to the parent ship so many miles away.
“I don’t understand it.” Lablet’s voice arose almost plaintively. “They were so very persuasive about our accompanying them. They were eager to have us see their treasures—”
Hobart swung around. “Somehow the balance of power has changed,” he observed, “in their favor. I’d give anything to know more about that prisoner of theirs. You’re sure it wasn’t one of the furry people?” he asked Raf, as if hoping against hope that the pilot would reply in doubt.
“Yes, sir.” Raf hesitated. Should he air his suspicions, that the captive was not of the same race as his captors either? But what proof had he beyond a growing conviction that he could not substantiate?
“A rebel, a thief—” Lablet was ready to dismiss it as immaterial. “Naturally they would be upset if they were having trouble with one of their own men. But to leave now, just when we are on the verge of new discoveries—That antigravity unit alone is worth our whole trip! Imagine being able to return to earth with the principle of that!”
“Imagine being able to return to earth with our skins on our backs,” was Soriki’s whispered contribution. “If we had the sense of a Venusian water nit, we’d blast out of here so quick our tail fumes’d take off with us!”
Privately Raf concurred, but the urge to know more about the mysterious prisoner was still pricking at him, until he, contrary to his usual detachment, felt driven to discover all that he could. It was almost, but Raf shied away from that wild idea, it was almost as if he were hearing a voiceless cry for aid, as if his mind was one of Soriki’s coms tuned in on an unknown wave length. He was angrily impatient with himself for that fantastic supposition. At the same time, another part of his mind, as he walked to the edge of the roof and looked out at the buildings he knew were occupied by the aliens, was busy examining the scene as if he intended to crawl about on roof tops on a second scouting expedition.
Finally the rest decided that Lablet and Hobart were to try to establish contact with the aliens once more. After they had gone, Raf opened a compartment in the flitter, the contents of which were his particular care. He squatted on his heels and surveyed the neatly stowed objects inside thoughtfully. A survival kit depended a great deal on the type of terrain in which the user was planning to survive—an aquatic world would require certain basic elements, a frozen tundra others—but there were a few items common to every emergency, and those were now at Raf’s fingertips. The blast bombs, sealed into their pexilod cases, guaranteed to stop all the attackers that Terran explorers had so far met on and off worlds, a coil of rope hardly thicker than a strand of knitting yarn but of inconceivable toughness and flexibility, an aid kit with endurance drugs and pep pills which could keep a man on his feet and going long after food and water failed. He had put them all in their separate compartments.
For a long moment he hunkered there, studying the assortment. And then, almost as if some will other than his own was making a choice, he reached out. The rope curled about his waist under his tunic so tautly that its presence could not be detected without a search, blast bombs went into the sealed seam pocket on his breast, and two flat containers with their capsules were tucked away in his belt pouch. He snapped the door shut and got to his feet to discover Soriki watching him. Only for a moment was Raf disconcerted. He knew that he would not be able to explain why he must do what he was going to do. There was no reason why he should. Soriki, except for being a few years his senior, had no authority over him. He was not under the com-tech’s orders.
“Another trip into the blue?”
The pilot replied to that with a nod.
“Somehow, boy, I don’t think anything’s going to stop you, so why waste my breath? But use your homer—and your eyes!”
Raf paused. There was an unmistakable note of friendliness in the com-tech’s warning. Almost he was tempted to try and explain. But how could one make plain feelings for which there was no sensible reason? Sometimes it was better to be quiet.
“Don’t dig up more than you can rebury.” That warning, in the slang current when they had left Terra, was reassuring simply because it was of the earth he knew. Raf grinned. But he did not head toward the roof opening and the ramp inside the building. Instead he set a course he had learned in the other city, swinging down to the roof of the neighboring structure, intent on working away from the inhabited section of the town before he went into the streets.
Either the aliens had not set any watch on the Terrans or else all their interest was momentarily engaged elsewhere. Raf, having gone three or four blocks in the opposite direction to his goal, made his way through a silent, long deserted building to the street without seeing any of the painted people. In his ear buzzed the comforting hum of the com, tying him with the flitter and so, in a manner, to safety.
He knew that the alien community had gathered in and around the central building they had visited. To his mind the prisoner was now either in the headquarters of the warriors, where the globe had been berthed, or had been taken to the administration building. Whether he could penetrate either stronghold was a question Raf did not yet face squarely.
But the odd something which tugged at him was as persistent as the buzz in his earphones. And an idea came. If he were obeying some strange call for assistance, couldn’t that in some way lead him to what he sought? The only difficulty was that he had no way of being more receptive to the impulse than he now was. He could not use it as a compass bearing.
In the end he chose the Center as his goal, reasoning that if the prisoner were to be interviewed by the leaders of the aliens, he would be taken to those rulers, they would not go to him. From a concealed place across from the open square on which the building fronted, the pilot studied it carefully. It towered several stories above the surrounding structures, to some of which it was tied by the ways above the streets. To use one of those bridges as a means of entering the headquarters would be entirely too conspicuous.
As far as the pilot was able to judge, there was only one entrance on the ground level, the wide front door with the imposing picture-covered gates. Had he had free use of the flitter he might have tried to swing down from the hovering machine after dark. But he was sure that Captain Hobart would not welcome the suggestion.
Underground? There had been those ways in that other city, a city which, though built on a much smaller scale, was not too different in general outline from this one. The idea was worth investigation.
The doorway, which had afforded him a shelter from which to spy out the land, yielded to his push, and he went through three large rooms on the ground floor, paying no attention to the strange groups of furnishings, but seeking something else, which he had luck to find in the last room, a ramp leading down.
It was in the underground that he made his first important find. They had seen ground vehicles in the city, a few still in operation, but Raf had gathered that the fuel and extra parts for the machines were now so scarce that they were only used in emergencies. Here, however, was a means of transportation quite different, a tunnel through which ran a ribbon of belt, wide enough to accommodate three or four passengers at once. It did not move, but
