As Malone knew perfectly well, the main portion of the entire Yucca Flats area was devoted solely to research on the new space drive which was expected to make the rocket as obsolete as the blunderbuss--at least as far as space travel was concerned. Not, Malone thought uneasily, that the blunderbuss had ever been used for space travel, but-- He got off the subject hurriedly. The jeep whizzed by buildings, most of them devoted to aspects of the non-rocket drive. The other projects based at Yucca Flats had to share what space was left--and that included, of course, the Westinghouse research project. It turned out to be a single, rather small white building with a fence around it. The fence bothered Malone a little, but there was no need to worry; this time he was introduced at once into Dr. O'Connor's office. It was paneled in wallpaper manufactured to look like pine, and the telepathy expert sat behind a large black desk bigger than any Malone had ever seen in the FBI offices. There wasn't a scrap of paper on the desk; its surface was smooth and shiny, and behind it the nearly transparent Dr. Thomas O'Connor was close to invisible. He looked, in person, just about the same as he'd looked on the FBI tapes. Malone closed the door of the office behind him, looked for a chair and didn't find one. In Dr. O'Connor's office, it was perfectly obvious, Dr. O'Connor sat down. You stood, and were uncomfortable. * * * * * Malone took off his hat. He reached across the desk to shake hands with the telepathy expert, and Dr. O'Connor gave him a limp and fragile paw. "Thanks for giving me a little time," Malone said. "I really appreciate it." He smiled across the desk. His feet were already beginning to hurt. "Not at all," Dr. O'Connor said, returning the smile with one of his own special quick-frozen brand. "I realize how important FBI work is to all of us, Mr. Malone. What can I do to help you?" Malone shifted his feet. "I'm afraid I wasn't very specific on the phone last night," he said. "It wasn't anything I wanted to discuss over a line that might have been tapped. You see, I'm on the telepathy case." Dr. O'Connor's eyes widened the merest trifle. "I see," he said. "Well, I'll certainly do everything I can to help you." "Fine," Malone said. "Let's get right down to business, then. The first thing I want to ask you about is this detector of yours. I understand it's too big to carry around--but how about making a smaller model?" "Smaller?" Dr. O'Connor permitted himself a ghostly chuckle. "I'm afraid that isn't possible, Mr. Malone. I would be happy to let you have a small model of the machine if we had one available--more than happy. I would like to see such a machine myself, as a matter of fact. Unfortunately, Mr. Malone--" "There just isn't one, right?" Malone said.
