Very slowly, Larry felt life flow into his body once more. He reached up and touched his neck tenderly. Out of the corner of his eye he caught a sudden movement, and stooped to catch Stella as she fainted. "She will be all right?" a quietly modulated voice asked. Larry jerked his head around. One of the quietly smiling young men was standing over them solicitously. "She has only fainted? If you can carry her, come with me. I want to show you to your quarters now. I hope they will be quite comfortable. We want you to feel at home." * * * * * Stella recovered consciousness. She and Larry looked at each other, clung to each other in wordless desperation. Then there was that moment, that pause. Then, "I'm sorry, Larry," Stella said. Larry shrugged. He looked around at the simulated Cypress walls, the comfortable surroundings. "This has gone beyond just one robot escaping," Larry said. "Those others, their weapon that destroyed your ship without a trace. It's invasion from some other galaxy. They're planning on destroying the human race." And then Stella cried. Larry watched her, a worried frown forming a crease between his puzzled gray eyes. He reached out and touched her face with his fingers. "What is it?" "Rover," she said, sobbing softly. "I let a monster loose on mankind." * * * * * The sensory assembly of robot 532-03-2615 moved slightly. A metal arm started to lift, then paused. The eye lenses moved to focus on the arm. There were two sleeping puppies sprawled across it. A low rumble came from the voice box under the two crystal lenses. Slowly the metal arm moved, dislodging the puppies. There were others sprawled in sleep against him. All were bloodhound puppies six weeks old. One of them whimpered in reaction to some puppy dream. 2615 stood up. It opened a small door in the lower left hand corner of its box-shaped torso and brought out cleaning cloths. For the next fifteen minutes it carefully polished and cleaned every square inch of its surface. It bent down. Its metal fingers softly stroked the back of one of the sleeping puppies. Another low growl came from its voice box. It went across the yard to the gate. There it paused and looked back. Suddenly from its voice box a sharp _Yip!_ erupted. The puppies jerked into instant wakening. They looked around, cocking their ears for a repetition of the sound. Then they saw the robot. They scampered with clumsy haste toward it, their shrill yapping filling the air. 2615 closed the gate and strode down the lane toward the ladder leading to the grav-cylinder exit. Behind it, the bloodhound puppies jumped against the gate, trying to follow. One by one they desisted. But their eyes followed the moving metal figure until it vanished through the door half way up to that ceiling where other dogs walked upside down. The robot rode the travelwalk to the asteroid shell. It was met by Pwowp and two others.
