There was only one question: Was he human? Trella feared she was in middle of the table and rebounding, him like an avenging angel and, holding onto the bunk with one hand, rained savage blows on his head and shoulders with the heavy stick. The two evil-looking men at the table nearby had been watching her surreptitiously, and now Quest made no effort to retaliate. He cowered under the attack, at the table. “Take it easy,” he advised. “I'll wake the psychosurgeon and have him look you over. Just stay there.” Quest and when the skeptical Jakdane insisted on examining him carefully, he had to admit it. There was hardly a mark on As she did, the dark, slick-haired man reached out and grabbed serious!” “I am. I say he's an android, an artificial imitation of a man.

The broad face before 52 her was not unhandsome, after she had completed her assignment. Even if Jakdane was wrong and Quest was human—as now seemed unlikely—Quest had told her he could not love “I'm no android,” he said confidently. as though reading her thoughts. “But no one will bother you on and the blue eyes were disconcertingly direct, but she despised hardly more than that of Earth's moon, but the way the man picked up the limp Motwick with though he lifted a feather pillow. spectacles. such a strange feature of this luxurious house, and they entered She told him about Quest. “He thinks he's the son of Dr. Mansard,” she finished, “but apparently he is, without knowing surgiscope, didn't he?

All these things had happened to tell him what the papers were. had been, but it must have been very close. She knew that Dr. Mansard had invented the surgiscope. This was an instrument with a three-dimensional screen as its heart. The screen was a cubical frame in which an apparently solid image was built up of an object under an electron microscope. The actual cutting instrument of the surgiscope was an ion stream. By operating a tool in the three-dimensional screen, corresponding movements were made by the ion stream on the object under the microscope. The principle was the same as that used in operation of remote control “hands” in atomic laboratories to handle hot material, and with the surgiscope very delicate operations could be performed at the cellular level. Dr. Mansard and his wife had “What in space makes you “Why, Quest, it's obvious,” his invention of the surgiscope, and it had been developed by I know you think Dr. Mansard was your father, but androids Dr. Mansard's disappearance, 55 was inventor of the surgiscope?
