By the public nonspace and air systems, he would move anywhere on earth within hours; and wherever he went, any human being within the range of his mind became a potential tool. He could order death at will and be at a safe distance when the order was executed. Within ten weeks, he had Special Activities on the ropes. The attempts to identify him were called off. And the abnormal series of disasters promptly ended. The rogue had made his point.”
Arlene said soberly, “You say he attacked some of your investigators later on. What was that about?”
“That was a year later,” Weldon said. “A kind of stalemate had developed. As you’re aware, the few operating telepaths in the government’s employment are a daintily handled property. They’re never regarded as expendable. It was clear they weren’t in the rogue’s class, so no immediate attempt was made to use them against him. But meanwhile we’d assembled—almost entirely by inference—a much more detailed picture of this opponent of mankind than DEDCOM had been able to provide. He was a freak in every way. His ability to read other minds and to affect them—an apparent blend of telepathy and irresistible hypnosis—obviously was a much more powerful and definite tool than the unreliable gropings of any ordinary telepath. But there was the curious point that he appeared to be limited—very sharply limited—simply by distance, which to most of our trained telepaths is a meaningless factor, at least this side of interplanetary space. If one stayed beyond his range, the rogue was personally harmless. And if he could be identified from beyond his range, he also could be—and f
