But outside were waiting the radio and television men; he had work to do. He turned and went to them and all got busy.
An hour later Cliff sat alone about fifteen feet above the ground in a big tree which, located just across the walk from the building, commanded through a window a clear view of the upper part of Gnut's body. Strapped to the limbs about him were three instruments-his infrared viewing magnifier, a radio mike, and an infrared television eye with sound pickup. The first, the viewing magnifier, would allow him to see in the dark with his own eyes, as if by daylight, a magnified image of the robot, and the others would pick up any sights and sounds, including his own remarks, and transmit them to the several broadcast studios which would fling them millions of miles in all directions through space. Never before had a picture man had such an important assignment, probably-certainly not one who forgot to take pictures. But now that was forgotten, and Cliff was quite proud, and ready.
Far back in a great circle stood a multitude of the curious-and the fearful. Would the plastic glasstex hold Gnut? If it did not, would he come out thirsting for revenge? Would unimaginable beings come out of the traveler and release him, and perhaps exact revenge? Millions at their receivers were jittery; those in the distance hoped nothing awful would happen, yet they hoped something would, and they were prepared to run.
In carefully selected spots not far from Cliff on all sides were mobile ray batteries manned by army units, and in a hollow in back of him, well to his right, there was stationed a huge tank with a large gun. Every weapon was trained on the door of the wing. A row of smaller, faster tanks stood ready fifty yards directly north. Their ray projectors were aimed at the door, but not their guns. The grounds about the building contained only one spot-the hollow where the great tank was-where, by close calculation, a shell directed at the doorway would not cause damage and loss of life to some part of the sprawling capital.
Dusk fell; out streamed the last of the army officers, politicians, and other privileged ones; the great metal doors of the wing clanged to and were locked for the night. Soon Cliff was alone, except for the watchers at their weapons scattered around him.
Hours passed. The moon came out. From time to time Cliff reported to the studio crew that all was quiet. His unaided eyes could now see nothing of Gnut but the two faint red points of his eyes, but through the magnifier he stood out as clearly as if in daylight from an apparent distance of only ten feet. Except for his eyes, there was no evidence that he was anything but dead and unfunctionable metal.
Another hour passed. Now and again Cliff thumbed the levels of his tiny radio-television watch-only a few seconds at a time because of its limited battery. The air was full of Gnut and his own face and his own name, and once the tiny screen showed the tree in which he was then sitting and even, minutely, himself. Powerful infrared long-distance television pickups were even then focused on him from nearby points of vantage. It gave him a funny feeling.
Then, suddenly, Cliff saw something and quickly bent his eye to the viewing magnifier. Gnut's eyes were moving; at least the intensity of the light emanating from them varied. It was as if two tiny red flashlights were turned from side to side, their beams at each motion crossing Cliffs eyes.
Thrilling, Cliff signaled the studios, cut in his pickups, and described the phenomenon. Millions resonated to the excitement in his voice. Could Gnut conceivably break out of that terrible prison?
Minutes passed, the eye flashes continued, but Cliff could discern no movement or attempted movement of the robot's body. In brief snatches he described what he saw. Gnut was clearly alive; there could be no doubt he was straining against the transparent prison in which he had at last been locked fast; but unless he could crack it, no motion should show.
Cliff took his eyes from the magnifier-and started. His unaided eye, looking at Gnut shrouded in darkness, saw an astonishing thing not yet visible through his instrument. A faint red glow was spreading over the robot's body. With trembling fingers he readjusted the lens of the television eye, but even as he did so the glow grew in intensity. It looked as if Gnut's body were being heated to incandescence!
He described it in excited fragments, for it took most of his attention to keep correcting the lens. Gnut passed from a figure of dull red to one brighter and brighter, clearly glowing now even through the magnifier. And then he moved! Unmistakably he moved!
He had within himself somehow the means to raise his own body temperature, and was exploiting the one limitation of the plastic in which he was locked. For glasstex, Cliff now remembered, was a thermoplastic material, one that set by cooling and conversely would soften again with heat. Gnut was melting his way out!
In three-word snatches, Cliff described this. The robot became cherry red, the sharp edges of the icelike block rounded, and the whole structure began to sag. The process accelerated. The robot's body moved more widely. The plastic lowered to the crown of his head, then to his neck, then to his waist, which was as far as Cliff could see. His body was free! And then, still cherry-red, he moved forward out of sight!
Cliff strained eyes and ears, but caught nothing but the distant roar of the watchers beyond the police lines and a few low, sharp commands from the batteries posted around him. They, too, had heard, and perhaps seen by telescreen, and were waiting.
Several minutes passed. There was a sharp, ringing crack; the great metal doors of the wing flew open, and out stepped the metal giant, glowing no longer. He stood stock-still, and his red eyes pierced from side to side through the darkness.
Voices out in the dark barked orders and in a twinkling Gnut was bathed in narrow, crisscrossing rays of sizzling, colored light. Behind him the metal doors began to melt, but his great green body showed no change at all. Then the world seemed to come to an end; there was a deafening roar, everything before Cliff seemed to explode in smoke and chaos, his tree whipped to one side so that he was nearly thrown out. Pieces of debris rained down. The tank gun had spoken, and Gnut, he was sure, had been hit.
Cliff held on tight and peered into the haze. As it cleared he made out a stirring among the debris at the door, and then dimly but unmistakably he saw the great form of Gnut rise to his feet. He got up slowly, turned toward the tank, and suddenly darted toward it in a wide arc. The big gun swung in an attempt to cover him, but the robot sidestepped and then was upon it. As the crew scattered, he destroyed its breech with one blow of his fist, and then he turned and looked right at Cliff.
He moved toward him, and in a moment was under the tree. Cliff climbed higher. Gnut put his two arms around the tree and gave a lifting push, and the tree tore out at the roots and fell crashing to its side. Before Cliff could scramble away, the robot had lifted him in his metal hands.
Cliff thought his time had come, but strange things were yet in store for him that night. Gnut did not hurt him. He looked at him from arm's length for a moment, then lifted him to a sitting position on his shoulders, legs straddling his neck. Then, holding one ankle, he turned and without hesitation started down the path which led westward away from the building.
Cliff rode helpless. Out over the lawns he saw the muzzles of the scattered field pieces move as he moved, Gnut-and himself-their one focus. But they did not fire. Gnut, by placing him on his shoulders, had secured himself against that-Cliff hoped.
