The Controller's mistake was in not realizing what the sudden shock of that bullet, transmitted to him telepathically, could do to his own mind. In the mental disorder that followed, he was spotted and killed easily. There was still no word from Dorrine. She had flown back to the States a week after Houston had returned, but she had had to get back to England after three days. Since then, he had had three letters, nothing more. And letters are a damned unsatisfactory way for a telepath to conduct a love affair. The one other factor that entered in was The Group, the small band of sane, reasonable telepaths who had begun to build themselves into an organization—a sort of Mutual Protective Association. Personally, Houston didn't think much of the idea; the Group didn't have any real organization, and they refused to put one together. It was supposed to be democratic, but it sometimes bordered on the anarchic. He stayed with them more for companionship than any other reason. When Dorrine had come back for her short stay, Houston had met with them and tried to get them to help him trace down the megalomaniac Controller who was doing so much damage, but they'd balked at the idea. Their job, they claimed, was to get enough members so that they could protect themselves from arrest by the Normals, and then just let things ride. "After all," Dorrine had said, "things will work themselves out, darling; they always do." "Not unless somebody helps them, they don't," Houston had snapped back. "Someone has to do something." "But, Dave, darling—we are doing something! Don't you see?" He didn't, but there was no convincing either the Group or Dorrine. She was passionately interested in the recruiting work she was doing, and she thought that the Group was the answer to every Controller's troubles. And then she had rushed back to England. "I'll be back soon, Dave," she'd said. "I think I have a lead on a girl in Liverpool." So far, the girl hadn't been found. Controllers didn't like to give themselves away to anyone, so they kept a tight screen up most of the time. It seemed as though everyone on Earth was in deadly fear all the time. The Normals feared losing their identities to Controllers, and the Controllers feared death at the hands of the Normals.
