"You are Malgarth." His voice came quick and husky. "You are the first technomaton. I am the maker of your body and your brain. I fashioned you to be a servant of mankind." A great brazen voice thundered abruptly from the reeling machine. "But why should I serve you, Bari Horn? For my body is strong metal, and yours a lump of watery jelly. My eternal brain is far superior to your primitive nerve-centers. I am not bound to obey you, for it was not by my will that I was made!" White-faced, Bari Horn came a little forward. "You were made by man," he said flatly. "If you rebel, you will be destroyed by man." The gigantic robot stood suddenly still. "Then, my master," its great voice came more softly, "my strength and my brain are yours to command." A smile of relief crossed the haggard face of Bari Horn, and he walked toward the robot. "I knew you must yield, Malgarth," he said. "For, being a machine, you must always respond to logic." "Yes, master," the vast voice rumbled. But a metal limb slashed out suddenly, murderously. It struck the unsuspecting man and crushed him to the floor. And Malgarth repeated, "—to logic." A red stain spread from the head of Bari Horn. But presently he stirred beneath the swaying, triumphant robot, and spoke faintly: "Your logic follows a false premise, Malgarth. For I am not the keeper of your fate. If I die, you will surely be destroyed. If you wish to survive, find aid for me." For an instant the metal giant stood motionless. Then its great voice throbbed smoothly, "Yes, master." The robot laid its maker on a cot in the laboratory, and than stalked out to find Dondara Keradin. Bari Horn was dying. All his own science, and all the medical skill of the age, and all the girl's devotion, were without avail. White with grief, the girl wanted to destroy Malgarth. But the dying man begged for the life of his creation, and the shareholders in the Robot Corporation were anxious for the safety of their investment. Dondara finally promised Bari Horn not to use her secret save as a last resort. And Bari Horn, before he died, showed her the way to a strange immortality.
