"Malone," Burris said, "I've tried. I've really tried. Believe me. I've tried to get used to the fact that you can teleport. But—"

"It's useful," Malone said, "in my work."

"I can see that," Burris said. "And I don't want you to ... well, to stop doing it. By no means. It's just that it sort of unnerves me, if you see what I mean. No matter how useful it is for the FBI to have an agent who can go instantaneously from one place to another, it unnerves me." He sighed. "I can't get used to seeing you disappear like an over-dried soap bubble, Malone. It does something to me—here." He placed a hand directly over his sternum and sighed again.

"I can understand that," Malone said. "It unnerved me, too, the first time I saw it. I thought I was going crazy, when that kid—Mike Fueyo—winked out like a light. But then we got him, and some FBI agents besides me have learned the trick." He stopped there, wondering if he'd been tactful. After all, it took a latent ability to learn teleportation, and some people had it, while others didn't. Malone, along 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 division. 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 FBI 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 the Cosmetic Surgery Division, 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 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.
