He sank to his knees and covered his face with his taloned hands. If only she would pity him and open the door a crack and let him see her! Just the sight of her would enable him to endure the loneliness and emptiness of space when he took the two captive lovers to Mars on the mother ship. Just the sight of her beautiful white body and her face so torn with grief and torment that he could scarcely bear to meet the accusing fury in her eyes. SEVEN On Earth a man named Peter Summers and his wife Ruth--two people out of Earth's teeming millions, but chosen with care because of their exceptional courage and comeliness of form--went about their daily affairs with no memory of what had happened to them on board a Martian ship a short month previously. Summers was a writer of mystery novels and his wife an artist whose paintings had been widely acclaimed by critics. They were quite ordinary people in some respects, brilliantly exceptional in others. They had both been used as models by Tragor in constructing experimental android men and android women, but those particular androids had been discarded as not quite what the Plan called for. The android who resembled Summers and the lithe-limbed, sultry-eyed robot-woman who was almost an exact duplicate of Summers' wife had not been destroyed, however. They had been kept immobilized in a laboratory on Mars, the disks on their thighs turned off. Summers and his wife had not been harmed. They had been released at the completion of what had been one of the earliest of the android-constructing experiments, with all knowledge of what had happened to them on board the Martian ship blotted from their minds. They were no longer of any interest to Tragor. However, the two androids who resembled them had now become of vital interest to Tragor, for the writer, Peter Summers, was a strong-willed, imaginative and sensitive man and greatly resembled the crucial figure in the entire Plan: David Loring. Not physically, but in the subtle and complex configuration of his mind, and that configuration had been duplicated in the robot-man fashioned in Summers' image. And Ruth Summers bore a quite striking resemblance, even physically, to the woman whom Loring loved. The man and the woman awoke and stared about them. The man was not Peter Summers. The woman was not Ruth, his wife. But the man resembled Peter Summers in all respects. He had the same physical build, the same eyes, ears, nose and mouth. Not only were his facial contours the same, his body was a twin-duplicate of Peter Summers' body. He moved in the same way, with the same gestures and mannerisms, and his voice would not have seemed in any way strange to his wife or to any of the people who knew him well.
