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?"
