When Eylan was finished with him, Barrent went to a small, beady-eyed man who lectured on Earth's memory-destroying system. Using the premise that memory-destruction was regularly employed to render opposition ineffective, the man went on to construct the probable nature of an underground movement on Earth given those circumstances, and how Barrent might contact them, and what the underground's capabilities might be. Finally he was given the full details of Group Two's plan for getting him on board the ship. When Landing Day came, Barrent felt a definite sense of relief. He was heartily sick of day and night cramming. Any sort of action would seem an improvement. Chapter Twenty-One Barrent watched the huge prison ship maneuver into position and sink noiselessly to the ground. It gleamed dully in the afternoon sun, tangible proof of Earth's long reach and powerful grasp. A hatch opened, and a landing stage was let down. The prisoners, flanked by guards, marched down and assembled in the square. As usual, most of the population of Tetrahyde had gathered to watch and cheer the disembarkation ceremony. Barrent moved through the crowd and stationed himself behind the ranks of prisoners and guards. He touched his pocket to make sure the needlebeam was still there. It had been made for him by Group Two fabricators, completely of plastic to escape any metals detector. The rest of his pockets were stuffed with equipment. He hoped he wouldn't have to use any of it. The loudspeaker voice began to read off the prisoners' numbers, as it had when Barrent had disembarked. He listened, knees slightly bent, waiting for the beginning of the diversion. The loudspeaker voice was coming to the end of the prisoner list. There were only ten left. Barrent edged forward. The voice droned on. Four prisoners left, three.... As the number of the last prisoner was announced, the diversion began. A black cloud of smoke darkened the pale sky, and Barrent knew that the Group had set fire to the empty barracks in Square A-2. He waited. Then it came. There was a stupendous explosion, blasting through two rows of empty buildings. The shock wave was staggering. Even before debris began to fall, Barrent was running toward the ship. The second and third explosions went off as he came into the ship's shadow. Quickly he stripped off his Omegan outer garments. Under them, he wore a facsimile of guard's uniform. Now he ran toward the landing stage. The loudspeaker voice was calling loudly for order. The guards were still bewildered. The fourth explosion threw Barrent to the ground. He got to his feet instantly and sprinted up the landing stage. He was inside the ship. Outside, he could hear the guard captain shouting orders. The guards were beginning to form into ranks, their weapons ready to use against the restive crowd. They were retreating to the ship in good order.
