with a few other agents, did. Burris evidently didn't, so he couldn't teleport, no matter how hard he tried or how many lessons he took.

"Well," Burris said, "I'm still unnerved. So please, Malone, when you come in here, or go out, use the door. All right?"

"Yes, sir," Malone said. He turned and went out. As he opened the door, he could almost hear Burris' sigh of relief. Then he banged it shut behind him and, feeling that he might as well continue with his spacebound existence, walked all the way to the elevator, and rode it downstairs to the FBI laboratories.

The labs, highly efficient and divided into dozens of departments, covered several floors. Malone passed through the Fingerprint section, filled with technicians doing strange things to great charts and slides, and frowning over tiny pieces of material and photographs. Then came Forgery Detection, involving many more technicians, many more slides and charts and tiny pieces of things and photographs, and even a witness or two sitting on the white bench at one side and looking lost and somehow civilian. Identification Classified was next, a great barn of a room filled with index files. The real indexes were in the sub-basement; here, on microfilm, were only the basic divisions. A man was standing in front of one of the files, frowning at it. Malone went on by without stopping.

Cosmetic Surgery Classification came next. Here there were more indexes, and there were also charts and slides. There was an agent sitting on a bench looking bored while two female technicians— classified as O&U for Old and Ugly in Malone's mind—fluttered around him, deciding what disguises were possible, and which of those was indicated for the particular job on hand. Malone waved to the agent, whom he knew very slightly, and went on. He felt vaguely regretful that the FBI couldn't hire prettier girls for Cosmetic Surgery, but the trouble was that pretty girls fell for the Agents, and vice versa, and this led to an unfortunate tendency toward only handsome and virile-looking disguises. The O&U division was unfortunate, he decided, but a necessity.

Chemical Analysis (III) was next. The Chemical Analysis Section was scattered over several floors, with the first stages up above. Division III, Malone remembered, was devoted to nonpoisonous substances, like clay or sand found in boots or trouser cuffs, cigar ashes and such. They were placed on the same floor as Fingerprints to allow free and frequent passage between the sections on the problems of plastic prints, made in putty or like substances, and visible prints, made when the hand is covered with a visible substance like blood, ketchup or glue.

Malone found what he was looking for at the very end of the floor. It was the Computer Section, a large room filled with humming, clacking and buzzing machines of an ancient vintage, muttering to themselves as they worked, and newer machines which were smaller and more silent. Lights were lighting and bells were ringing softly, relays were relaying and the whole room was a gigantic maze of calculating and control machines. What space wasn't filled by the machines themselves was filled by workbenches, all littered with an assortment of gears, tubes, spare relays, transistors, wires, rods, bolts, resistors and all the other paraphernalia used in building the machines and repairing them. Beyond the basic room were other, smaller rooms, each assigned to a particular kind of computer work.

The narrow aisles were choked here and there with men who looked up as Malone passed by, but most of them gave him one quick glance and went back to work. A few didn't even do that, but went right on concentrating on their jobs. Malone headed for a man working all alone in front of a workbench, frowning down at a complicated-looking mechanism that seemed to have neither head nor tail, and prodding at it with a long, thin screwdriver. The man was thin, too, but not very long; he was a little under average height, and he had straight black hair, thick-lensed glasses and a studious expression, even when he was frowning. He looked as if the mechanism were a student who had cut too many classes, and he was being kind but firm with it.

Malone managed to get to the man's side, and coughed discreetly. There was no response.

"Fred?" he said.

The screwdriver waggled a little. Malone wasn't quite sure that the man was breathing.

"Fred Mitchell," he said.

Mitchell didn't look up. Another second passed.

"Hey," Malone said. Then he closed his eyes and took a deep breath.
"Fred," he said in a loud, reasonable-sounding voice, "the State
Department's translator has started to talk pig-Latin."

Mitchell straightened up as if somebody had jabbed him with a pin. The screwdriver waved wildly in the air for a second, and then pointed at Malone. "That's impossible," Mitchell said in a flat, precise voice. "Simply impossible. It doesn't have a pig-Latin circuit. It can't possibly—" He blinked and seemed to see Malone for the first time. "Oh," he said. "Hello, Malone. What can I do for you?"

Malone smiled, feeling a little victorious at having got through the Mitchell armor, which was almost impregnable when there was a job in hand. "I've been standing here talking to you for some time."

"Oh, have you?" Mitchell said. "I was busy." That, obviously, explained that. Malone shrugged.

"I want you to help me check over some calculators, Fred," he said. "We've had some reports that some of the government machines are out of kilter, and I'd like you to go over them for me."

"Out of kilter?" Fred Mitchell said. "No, you can forget about it. It's absolutely unnecessary to make a check, believe me. Absolutely. Forget it." He smiled suddenly. "I suppose it's some kind of a joke, isn't it?" he said, just a trifle uncertainly. Fred Mitchell's world, while pleasant, did not include much humor, Malone knew. "It's supposed to be funny," he said in the same flat, precise voice.

"It isn't funny," Malone said.

Fred sighed. "Then they're obviously lying," he said, "and that's all there is to it. Why bother me with it?"

"Lying, Fred?" Malone said.

"Certainly," Fred said. He looked at the machinery with longing.

Malone took a breath. "How do you know?" he said.

Fred sighed. "It's perfectly obvious," he said in a patient tone. "Since the State Department translator has no pig-Latin circuit, it can't possibly be talking pig-Latin. I will admit that such a circuit would be relatively easy to build, though it would have no utility as far as I can see. Except, of course, for a joke." He paused. "Joke?" he said, in a slightly uneasy tone.

"Sure," Malone said. "Joke."

Mitchell looked relieved. "Very well, then," he began. "Since—"

"Wait a minute," Malone said. "The pig-Latin is a joke. That's right.
But I'm not talking about the pig-Latin."

"You're not?" Mitchell asked, surprised.

"No," Malone said.

Mitchell frowned. "But you said—" he began.

"A joke," Malone said. "You were perfectly right. The pig-Latin is a joke." He waited for Fred's expression to clear, and then added: "But what I want to talk to you about isn't."

"It sounds very confused," Fred said after a pause. "Not at all the sort of thing that—that usually goes on."

"You have no idea," Malone said. "It's about the political machines, all right, but it isn't anything as simple as pig-Latin." He explained, taking his time over it.

When he had finished, Fred was nodding his head
