Leibowitz nodded slowly. "We can, Mr. Malone," he said. "They betray themselves. A microcircuit need not be more than a few microns thick, you see--as far as the conductors and insulators are concerned, at any rate. But the regulators--transistors and such--have to be as big as a pinhead."
"Enormous, huh?" Malone said.
"Well," Leibowitz said, and chuckled, "quite large enough to locate without trouble, at any rate. They"re very hard to conceal. And the leads from the brain to the power controls are even easier to find--comparatively speaking, of course."
"Of course," Malone said.
"All the brain does, you see," Leibowitz said, "is control the mechanism that steers the car. But it takes real power to steer--a great deal more than it does to compute the steering."
"I see," Malone, who didn"t, said desperately. "In other words, unless something radically new has been developed, you can find the circuits."
"Right," Leibowitz said, grinning. "It would have to be something very new indeed, Mr. Malone. We"re up on most of the latest developments here; we"ve got to be. But I don"t want the credit for this."
"No?" Malone said.
"Oh, no," Leibowitz said. "All I do is work out the general application to theory, as far as actual detection is concerned. It"s my partner, Mr.
Hardin, who takes care of all the engineering details."
Malone said: "Well, so long as one of you--"
"Sal"s a real crackerjack," Leibowitz said enthusiastically. "He has an intuitive feel about these things. It"s really amazing to watch him go to work."
"It must be," Malone said politely.
"Oh, it really is," Leibowitz said. "And it"s because of Sal that I can make the guarantee I do make: that if there are any unusual circuits in those cars, we can find them."
"Thanks," Malone said. "I"m sure you"ll do the job. And we need that information. Don"t bother to send along a detailed report, though, unless you find something out of the ordinary."
"Of course, Mr. Malone," Leibowitz said. "I wouldn"t have bothered you except for the production speed-up here."
"I understand," Malone said. "It"s perfectly all right. I"ll be hearing from you, then?"
"Certainly, Mr. Malone," Leibowitz said.
Malone cut the circuit at once and started to turn away, but he never got the chance. It started to chime again at once.
"Federal Bureau of Investigation," Malone said as he flipped up the receiver. He wanted badly to copy Boyd"s salutation, but he found that he just didn"t have the gall to do it, and said sadly instead: "Malone speaking."
There was no immediate answer from the other party. Instead, the screen slowly cleared, showing Malone the picture of a woman he recognized instantly.
It was Juanita Fueyo--Mike"s mother.
Malone stared at her. It seemed to him as if a couple of hours pa.s.sed while he tried to find his voice. Of course, she"d looked up the FBI number in the phone book, and found him that way. But she was about the last person on Earth from whom he"d expected a call.
"Oh, Mr. Malone," she said, "thank you so much! You got my Mike back from the police!"
Malone gulped. "I did?" he said. "Well, I--"
"But Mr. Malone--you must help me again! Because now my Mike says he must not stay at home! He is leaving, he is leaving right away!"
"Leaving?" Malone said.
He thought of a thousand things to do. He could send a squad of men to arrest Mike. And Mike could disappear while they were trying to get hold of him. He could go down himself--and be greeted, if he knew Mike Fueyo, with another giant economy-size raspberry. He could try to plead with Mike on the phone.
And what good would that do?
So, instead, he just sat and stared while Mrs. Fueyo went right on.
"He says he will send me money, but money is nothing compared to my own boy, my own Mike. He says he must go away, Mr. Malone--but I know you can stop him! I know it!"
"Sure," Malone said. "But I--"
"Oh, I knew that you would!" Mrs. Fueyo shrieked. She almost came through the screen at him. "You are a great man, Mr. Malone! I will say many prayers for you! I will never stop from praying for you because you help me!" Her voice and face changed abruptly. "Excuse me now," she said. "I must go back to work."
"Well," Malone said, "if I--"
Then she turned back and beamed at him again. "Oh, thank you, Mr.
Malone! Thank you with the thanks of a mother! Bring my boy back to me!"
And the image faded and died.
Boyd tapped Malone on the shoulder. "I didn"t know you were involved in an advice column for the lovelorn," he said.
"I"m not," Malone said sourly.
Boyd sighed. "I"ll bite," he said. "Who was that?"
Malone thought of several possible answers and finally chose one.
"That," he said, "was my mother-in-law. She worries about me every time I go out on a job with you."
"Very funny," Boyd said. "I am screaming with laughter."
"Just get back to work, Tommy-boy," Malone said, "and leave everything to me."
He hoped he sounded more confident than he felt. Lighting a cigarette--and wishing he were alone in his own room, so that he could smoke a cigar and not have to worry about looking dashing and alert--Malone strolled out of the office with a final wave to Boyd. He was thinking about Mike Fueyo, and he stopped his chain of reasoning just long enough to look in at the office of the Agent-in-Charge and ask him to pry loose two tickets for "The Hot Seat" that night.
The agent, a tall, thin man, who looked as if he suffered from chronic stomach trouble, said, "You must be crazy. Are they all like that in Washington?"
"No," Malone said cheerfully. "Some of them are pretty normal. There"s this one man--Napoleon, we call him--who keeps insisting that he should have won the battle of Waterloo. But otherwise he"s perfectly fine."
He flicked his cigarette in the air and left, grinning. Five steps away the grin disappeared and a frown took its place.
