Nearby was a ladder that led to a trap door which would put him in the hall of a tenement. He climbed it, emerged, and then turned up the regular steps to the roof. He walked across the tar-paper surface to the edge, leaned over, and peered into the alley. Two men, who may have been the people following him, approached from opposite ends of the alley. The sky was deepening toward evening and it was cool. The two men met, and then one pointed to the roof. "Damn," Tel muttered, ducked backward, and bit his tongue with surprise. He opened his mouth and breathed hard, holding the side of his jaw. The helicopter was coming closer. Then something very light fell over him. He forgot his bitten tongue and struck out with his hands. It was strong, too. It jerked at his feet and he fell forward. It was not until it lifted him from the roof that he realized he was caught in a net. He was being drawn up toward the sound of the whirling helicopter blades. * * * * * Just about that time the order came through. He didn't even have time to say good-bye to Clea. Two other mathematicians in the corps had shown appropriate awe at Clea's discovery and proceeded to locate the generator. The next-in-charge general, working on a strategy Tomar did not quite understand, decided that now was the time for an active strike. "Besides," he added, "if we don't give them some combat soon, we'll lose--and I mean lose as in 'misplace'--the war." The shadow of the control tower fell through the windshield and slipped across Tomar's face. He pulled up his goggles and sighed. Active combat. What the hell would they be combating? The disorder, the disorganization was beginning to strike him as farcical. Though after the poisoned fish, the farcical was no longer funny. The buildings on the airfield sunk back and down. The transit ribbon fell below him and the six other planes in the formation pulled up behind him. A moment later the island was a comb of darkness on the glittering foil of the evening sea. Clouds banded the deep blue at the horizon. There were three stars out, the same stars that he had looked at as a boy when his sunup to sundown work day had ended. Between hunger and hunger there had been some times when you could look at the stars and wonder, as there were now between times of work and work. The controls were set. There was nothing to do but wait for land to rise up over the edge of the world. * * * * * As the end of the metal ribbon was a transparent crystal sphere, fifteen feet in diameter which hovered above the receiving stage. A dozen small tetron units sat around the room. By one ornate window a bank of forty-nine scarlet knobbed switches pointed to off. Two men stood on the metal catwalk that ran above the receiving stage, one young man with black hair, the other a dark giant with a triplex of scars down the left side of his face.
