THE OTHER LIKENESS _There is a limit to how perfect a counterfeit can be--a limit that cannot be passed without an odd phenomenon setting in...._ BY JAMES H. SCHMITZ ILLUSTRATED BY SCHELLING When he felt the sudden sharp tingling on his skin which came from the alarm device under his wrist watch, Dr. Halder Leorm turned unhurriedly from the culture tray he was studying, walked past the laboratory technician to the radiation room, entered it and closed the door behind him. He slipped the instrument from his wrist, removed its back plate, and held it up to his eye. He was looking into the living room of his home, fifty miles away in another section of Orado's great city of Draise. A few steps from the entry, a man lay on his back on the carpeting, eyes shut, face deeply flushed, apparently unconscious. Halder Leorm's mouth tightened. The man on the carpet was Dr. Atteo, his new assistant, assigned to the laboratory earlier in the week. Beyond Atteo, the entry from the residence's delivery area and car port stood open. Fingering the rim of the tiny scanner with practiced quickness, Halder Leorm shifted the view to other sections of the house, finally to the car port. An empty aircar stood in the port; there was no one in sight. Halder sighed, replaced the instrument on his wrist, and glanced over at a wall mirror. His face was pale but looked sufficiently composed. Leaving the radiation room, he picked up his hat, said to the technician, "Forgot to mention it, Reef, but I'll have to head over to central laboratories again." [Illustration] Reef, a large, red-headed young man, glanced around in mild surprise. "They've got a nerve, calling you across town every two days!" he observed. "Whose problem are you supposed to solve now?" "I wasn't informed. Apparently, something urgent has come up and they want my opinion on it." "Yeah, I bet!" Reef scratched his head, glanced along the rows of culture trays. "Well ... nothing here at the moment I can't handle, even if Atteo doesn't show up. Will you be back before evening?" "I wouldn't count on it," Halder said. "You know how those conferences tend to go." "Uh-huh. Well, Dr. Leorm, if I don't see you before tomorrow, give my love to your beautiful wife." Halder smiled back at him from the door. "Will do, Reef!" He let the door slide shut behind him, started towards the exit level of the huge pharmaceutical plant. Reef had acted in a completely normal manner. If, as seemed very probable, "Dr. Atteo" was a Federation agent engaged in investigating Dr. Halder Leorm, Halder's co-workers evidently had not been apprised of the fact. Still, Halder thought, he must warn Kilby instantly. It was quite possible that an attempt to arrest him would be made before he left the building.
