lights wouldn't awaken a sleeping person. In normal sleep, a telepath retained enough control to keep his thoughts to himself, even when waking up. But total anaesthesia brought on a mental blackout from which the victim recovered only with effort. And during that time, a Controller's mind was violently disturbing to the Normal minds around him, who mistook his disordered thoughts for their own. Like pouring heavy oil on choppy waters, Houston soothed the disturbances of Harris's mind, focusing the random broadcasts on his own brain. And while he did that, he probed gently into the weakened mind of the prisoner for information. Harris was a Controller, all right; there was no doubt about that. But nowhere in his mind was there any trace of any knowledge of what had happened to Sir Lewis Huntley. If Sir Lewis had actually been controlled, it hadn't been done by Robert Harris. Houston wished he'd been able to probe Sir Lewis's mind; he'd have been able to get a lot more information out of it than he had in his possession now. But that would have been dangerous; if Sir Lewis was a Controller himself, and had been acting a part, Houston would have given himself away the instant he attempted to touch the baronet's mind. If, on the other hand, Sir Lewis had actually been under the control of another telepath, any probing into the mind of the puppet would have betrayed Houston to the real Controller. Harris knew nothing. He wasn't acquainted with any other Controllers, and had kept his nose clean ever since he'd discovered his latent powers. He knew that megalomaniac Controllers were either captured or mobbed, and he had no wish to experience either. The Normals had long since discovered that the only way to overcome a Controller was by force of numbers. A Controller could only hold one Normal mind at a time. That was why a mob could easily kill a single Controller; that was why the Psychodeviant Police had evolved the "net" system for arresting a telepath. Harris, then, had been framed. Or could it be called a frame-up when Harris was really guilty of the actual crime? Because the crime he had really been accused of was not that of controlling Sir Lewis, but the crime of being a telepath. That, and that alone, damned him in the eyes of the Normals; the crime of taking over a mind for gain was incidental. The stigma lies in what he was, not what he did.
