Sir Lewis was a tall, solidly-built man with a kindly expression. He wore gray flannel trousers and a brown tweed jacket, which made an interesting color contrast with his iron-gray hair. His teeth were clenched so firmly on the bit of a calabash pipe with a meerschaum bowl that Malone wondered if he could ever get loose. Malone shut the door behind him, and Sir Lewis rose and extended a hand. Malone went to the desk and reached across to take the hand. It was firm and dry. "I'm Kenneth Malone," Malone said. "Ah, yes," Sir Lewis said. "Pleased to meet you; always happy, of course, to do whatever I can for your FBI. Not only a duty, so to speak, but a pleasure. Sit down. Please do sit down." Malone found a chair at the side of the desk, and sank into it. It was soft and comfortable. It provided such a contrast to O'Connor's furnishings that Malone began to wish it was Sir Lewis who was employed at Yucca Flats. Then he could tell Sir Lewis everything about the case. Now, of course, he could only hedge and try to make do without stating very many facts. "Sir Lewis," he said, "I trust you'll keep this conversation confidential." "Naturally," Sir Lewis said. He removed the pipe, stared at it, and replaced it. "I can't give you the full details," Malone went on, "but the FBI is presently engaged in an investigation which requires the specialized knowledge your organization seems to have." "FBI?" Sir Lewis said. "Specialized investigation?" He seemed pleased, but a trifle puzzled. "Dear boy, anything we have is at your disposal, of course. But I quite fail to see how you can consider us--" "It's rather an unusual problem," Malone said, feeling that that was the understatement of the year. "But I understand that your records go back nearly a century." "Quite true," Sir Lewis murmured. "During that time," Malone said, "the Society investigated a great many supposedly supernatural or supernormal incidents." "Many of them," Sir Lewis said, "were discovered to be fraudulent, I'm afraid. The great majority, in fact." "That's what I'd assume," Malone said. He fished in his pockets, found a cigarette and lit it. Sir Lewis went on chewing at his unlit pipe. "What we're interested in," Malone said, "is some description of the various methods by which these frauds were perpetrated." "Ah," Sir Lewis said. "The tricks of the trade, so to speak?" "Exactly," Malone said. "Well, then," Sir Lewis said. "The luminous gauze, for instance, that passes for ectoplasm; the various methods of table-lifting; control of the ouija board--things like that?" "Not quite that elementary," Malone said. He puffed on the cigarette, wishing it was a cigar. "We're pretty much up to that kind of thing. But had it ever occurred to you that many of the methods used by phony mind-reading acts, for instance, might be used as communication methods by spies?"
