Half an hour later, Barrent still hadn't figured out a way of getting past the check squad. They had finished inspecting the lower levels and were moving up to the control room deck. Barrent could hear them marching down the hallways. He kept on walking, a hundred yards in front, trying to find some way of hiding. There should be a staircase at the end of this passageway. He could take it down to a different level, a part of the ship which had already been searched. He hurried on, wondering if he were wrong about the location of the staircase. He still had only the haziest idea of the layout of the ship. If he were wrong, he would be trapped. He came to the end of the corridor, and the staircase was there. The footsteps behind him sounded closer. He started down, peering backwards over his shoulder. And ran headfirst into a man's huge chest. Barrent flung himself back, bringing his plastic gun to bear on the enormous figure. But he stopped himself from firing. The thing that stood in front of him was not human. It stood nearly seven feet high, dressed in a black uniform with INSPECTION TEAM--ANDROID B212 stenciled on its front. Its face was a stylization of a human's, cleverly sculptured out of putty-colored plastic. Its eyes glowed a deep, impossible red. It swayed on two legs, balancing carefully, looking at Barrent, moving slowly toward him. Barrent backed away, wondering if a needlebeam could stop it. He never had a chance to find out, for the android walked past him and continued up the stairs. Stenciled on the back of its uniform were the words RODENT CONTROL DIVISION. This particular android, Barrent realized, was programmed only to look for rats and mice. The presence of a stowaway had made no impression on it. Presumably the other androids were similarly specialized. He stayed in an empty storage room on a lower level until he heard the sounds of the androids leaving. Then he hurried back to the control room. No guards came aboard. Exactly on schedule, the big ship left the checkpoint. Destination: Earth. * * * * * The rest of the journey was uneventful. Barrent slept and ate and, before the craft entered subspace, watched the endless spectacle of the stars through the viewport. He tried to visualize the planet he was coming to, but no pictures formed in his mind. What sort of a people built huge starships but failed to equip them with a crew? Why did they send out inspection teams, then give those teams the narrowest and most specialized sort of vision? Why did they have to deport a sizable portion of their population--and then fail to control the conditions under which the deportees lived and died? Why was it necessary for them to wipe the prisoners' minds clean of all memory of Earth? Barrent couldn't think of any answers.
