above. Division III, Malone remembered, was devoted to non-poisonous 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 kindly 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?"

"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 slowly. "I see," he said. "I understand just what you want me to do."

"Good," Malone said.

"I'll take a team over to the Senate Office Building," Fred said, "and check the computer-secretaries there. That way, you see, I'll be able to do a full running check on them without taking any one machine out of operation for too long."

"Sure," Malone said.

"And it shouldn't take long," Fred went on, "to find out just what the trouble is." He looked very confident.

"How long?" Malone asked.

Fred shrugged. "Oh," he said, "five or six days."

Malone repressed an impulse to scream. "Days?" he said. "I mean ... well, look, Fred, it's important. Very important. Can't you do the job any faster?"

Fred gave a little sigh. "Checking and repairing all those machines," he said, "is an extremely complex job. Sometimes, Malone, I don't think you realize quite how complex, and how delicate a job it is to deal with such a high-order machine. Why—"

"Wait a minute," Malone said. "Check and repair them?"

"Of course," Fred said.

"But I don't want them repaired," Malone said. Seeing the look of horror on Fred's face, he added hastily: "I only want a report from you on what's wrong, whether they are actually making errors or not. And if they are making errors, just what's making them do it. And just what kind of errors. See?"

Fred nodded very slowly. "But I can't just ... just leave them there," he said piteously. "In ... pieces and everything. It isn't right, Malone. It just isn't right."

"Well, then," Malone said with energy, "you go right ahead and repair them, if you want to. Fix 'em all up. But you can do that after you make the report to me, can't you?"

"I—" Fred hesitated. "I had planned to check and repair each machine on an individual basis—"

"The Congress can allow for a short suspension," Malone said. "Anyhow, they can now—or as soon as I get the word to them. Suppose you check all the machines first, and then get around to the repair work."

"It's not the best way," Fred demurred.

Malone discovered that it was his turn to sigh. "Is it the fastest?" he said.

Fred nodded.

"Then it's the best," Malone said. "How long?"

Fred rolled his eyes to the ceiling and calculated silently for a second. "Tomorrow morning," he announced, returning his gaze to Malone.

"Fine," Malone said. "Fine."

"But—"

"Never mind the buts," Malone said hurriedly. "I'll count on hearing from you tomorrow morning."

"Oh—" Fred said. "All right."

"And if it looks like sabotage," Malone added, "if the errors aren't caused by normal wear and tear on the machines—you let me know right away. Phone me. Don't waste an
