"That was as good an explanation as our medical department was able to provide, Mr. Burris. There was some malfunction—but—we like to say that he simply gave up. Living became too difficult for him."
"All right," Burris said after a pause. "This telepath of yours is dead, and there aren't any more where he came from. Or if there are, you don't know how to look for them. All right. But to get back to this machine of yours: it couldn't detect the boy's ability?"
Dr. O'Connor shook his head. "No, I'm afraid not. We've worked hard on that problem at Westinghouse, Mr. Burris, but we haven't yet been able to find a method of actually detecting telepaths."
"But you can detect—"
"That's right," Dr. O'Connor said. "We can detect the fact that a man's mind is being read." He stopped, and his face became suddenly morose. When he spoke again, he sounded guilty, as if he were making an admission that pained him. "Of course, Mr. Burris, there's nothing we can do about a man's mind being read. Nothing whatever." He essayed a grin that didn't look very healthy. "But at least," he said, "you know you're being spied on."
Burris grimaced. There was a little silence while Dr. O'Connor stroked the metal box meditatively, as if it were the head of his beloved.
At last, Burris said: "Dr. O'Connor, how sure can you be of all this?"
The look he received made all the previous conversation seem as warm and friendly as a Christmas party by comparison. It was a look that froze the air of the room into a solid chunk, Malone thought, a chunk you could have chipped pieces from, for souvenirs, later, when Dr. O'Connor had gone and you could get into the room without any danger of being quick-frozen by the man's unfriendly eye.
"Mr. Burris," Dr. O'Connor said in a voice that matched the temperature of his gaze, "please. Remember our slogan."
