Whitman's face was tight. "They do have records. Complete records. But the name of Roger Strang is curiously missing from the roster of graduates in 2075. Or any other year." He snubbed his cigarette angrily. "I wish you would tell me, and save us both much unpleasantness. Just who are you, Mr. Strang, and where do you come from?"

Strang stared at the man, his pulse pounding in his head. Filtering into his mind was a vast confusion, some phrase, some word, some nebulous doubt that frightened him, made him almost believe that gray-haired man in the chair before him. He took a deep breath, clearing his mind of the nagging doubt. "Look here," he said, exasperated. "When I was drafted for the Barrier Base, they checked for my origin, for my education and credentials. If they had been false, I'd have been snapped up right then. Probably shot—they were shooting people for chewing their fingernails in those days. I wouldn't have stood a chance."

Whitman nodded his head vigorously. "Exactly!" he snapped. "You should have been picked up. But you weren't even suspected until we did a little checking after that accident in the Labs building yesterday. Somehow, false credentials got through for you. Security does not like false credentials. I don't know how you did it, but you did. I want to know how."

"But, I tell you—" Roger stood up, fear suddenly growing in his mind. He lit a cigarette, took two nervous puffs, and set it down, forgotten, on the ash-tray. "I have a wife," he said shakily. "I married her in New York City. We had a son, born in a hospital in New York City. He went to school there. Surely there must be some kind of record—"

Whitman smiled grimly, almost mockingly. "Good old New York City," he snarled. "Married there, you say? Wonderful! Son born there? In the one city in the country where that information can never be checked. That's very convenient, Mr. Strang. Or whoever you are. I think you'd better talk."

Roger snubbed out the cigarette viciously. "My son," he said after a long pause. "He was murdered tonight. Shot down in his bed—"

The Security Chief's face went white. "Garbage!" he snapped. "What kind of a fool do you think I am, Strang? Your son murdered—bah! When the alarm went out for you I personally drove to your home. Oddly enough this wife of yours wasn't at home, but your son was. Nice little chap. He made us some coffee, and explained that he didn't know where his parents were, because he'd been asleep all night. Quietly asleep in his bed—"

The words were clipped out, and rang in Roger's ears, incredibly. His hand shook violently as he puffed his cigarette, burning his fingers on the short butt. "I don't believe it," he muttered hollowly. "I saw it happen—"

Whitman sneered. "Are you going to talk or not?"

Roger looked up helplessly. "I don't—know—" he said, weakly. "I don't know."
