"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."
Malone sighed. He fished in his pocket for a pack of cigarettes, found one, and extracted a single cigarette. He stuck it in his mouth and started fishing in various pockets for his lighter.
He sighed again. He preferred cigars, a habit he'd acquired from the days when he'd filched them from his father's cigar case, but his mental picture of the fearless and alert young FBI agent didn't include a cigar. Somehow, remembering his father as neither fearless nor, exactly, alert—anyway, not the way the movies and the TV screens liked to picture the words—he had the impression that cigars looked out of place on FBI agents.
And it was, in any case, a small sacrifice to make. He found his lighter and shielded it from the brisk wind. He looked out over water at the Jefferson Memorial, and was surprised that he'd managed to walk as far as he had. Then he stopped thinking about walking, and took a puff of his cigarette, and forced himself to think about the job in hand.
Naturally, the Westinghouse gadget had been declared Ultra Top Secret as soon as it had been worked out. Virtually everything was, these days. And the whole group involved in the machine and its workings had been transferred without delay to the United States Laboratories out in Yucca Flats, Nevada.
