"One man did refuse to play with him, and turned the case over to us. Lunko carried out his threat and produced the show, much to the delight of the scandal-mongers. It was outrageously libelous and we promptly closed the joint and took him in...."
"And then...."
"And then," croaked O'Hara, rolling his pop-eyes toward the ceiling and pursing his lips, "and then we let him go. He had a trunkful of data on many, many important people. Some of them, I hate to tell you, were my seniors in this very Service. We could do nothing about it, for, unfortunately, all the stuff he had on them was true. We might have sent him to the mines for a short term, but he would have retaliated by standing our entire civilization on its head with his exposures. We compromised by letting him escape and go into exile. The understanding was that he was never to come inside the orbit of Mars. A while after that, he was reported killed in a landslide on Europa. We shut the book and proceeded to forget him."
"He mimicked the character exactly?"
"Not exactly. Just enough to clearly indicate them. Although, I am convinced that, if he chose, he could have taken off any person he had studied, with enough fidelity to fool anybody except perhaps a man's own wife."
Neville gave a little start. That was the item that had slowed him the most. Had Lunko improved his technique to the extent that he could even fool a wife? Was the Carstairs he was trailing really Carstairs, or an understudy? He had deceived both his old friend and his own wife for a time, but even they had admitted noting a subtle change. Who was this phoney Carstairs? Where was the real Carstairs? Or, Neville wondered, was his original theory of drugs or hypnotism correct?
"Thank you, General," he said. "You have been a big help. I have to go over to Operations now and get the past and future itineraries of the showboat. In another hour, I may begin to know something about this case."
"It's nothing," said O'Hara, promptly closing his eyes and folding his knotty fingers on his breast. "It's all in the day's work. Luck to you."
Neville heard the click as the secret door lock was released and he knew the interview was terminated. He backed away, stepped through the door and out into the corridor.
