bothered to identify himself on that phone; anyone who had the number knew who they were calling. The mild-looking, plumpish, blond-haired man whose face came onto the screen was immediately recognizable.

"How's everything, Mr. Bending?" he asked with cordial geniality.

"Fine, Mr. Trask," Bending answered automatically. "And you?"

"Reasonable, reasonable. I hear you had the police out your way this morning." There was a questioning look in his round blue eyes. "No trouble, I hope."

Sam understood the question behind the statement. Vernon Trask was the go-between for some of the biggest black market operators in the country. Bending didn't like to have to deal with him, but one had very little choice these days.

"No. No trouble. Burglary in the night. Someone opened my safe and picked up a few thousand dollars, is all."

"I see." Trask was obviously wondering whether some black market operator would be approached by a couple of burglars in the next few days—a couple of burglars trying to peddle apparatus and equipment that had been stolen from Bending. There still were crooks who thought that the black market dealt in stolen goods of that sort.

"Some of my instruments were smashed," Bending said, "but none of them are missing."

"I'm glad to hear that," Trask said. And Bending knew he meant it. The black market boys didn't like to have their customers robbed of scientific equipment; it might reflect back on them. "I just thought I'd explain about missing our appointment this morning," Trask went on. "It was unavoidable; something unexpected came up."

Trask was being cagey, as always. He didn't talk directly, even over a phone that wasn't supposed to be tapped. Bending understood, though. Some of the robotics equipment he'd contracted to get from Trask was supposed to have been delivered that morning, but when the delivery agent had seen the police car out front, he'd kept right on going naturally enough.

"That's all right, Mr. Trask," Bending said. "What with all this trouble this morning, it actually slipped my mind. Another time, perhaps."

Trask nodded. "I'll try to make arrangements for a later date. Thanks a lot, Mr. Bending. Good-by."

Bending said good-by and cut the connection.

Samson Bending didn't like being forced to buy from the black market operators, but there was nothing else to do if one wanted certain pieces of equipment. During the "Tense War" of the late Sixties, the Federal and State governments had gone into a state of near-panic. The war that had begun in the Near East had flashed northwards to ignite the eternal Powder Keg of Europe. But there were no alliances, no general war; there were only periodic armed outbreaks, each one in turn threatening to turn into World War III. Each country found itself agreeing to an armistice with one country while trying to form an alliance with a second and defending itself from or attacking a third.

And yet, during it all, no one quite dared to use the Ultimate Weapons. There was plenty of strafing by fighter planes and sorties by small bomber squadrons, but there was none of the "massive retaliation" of World War II. There could be heard the rattle of small-arms fire and the rumble of tanks and the roar of field cannon, but not once was there the terrifying, all-enveloping blast of nuclear bombs.

But, at the time, no one knew that it wouldn't happen. The United States and the Soviet Union hovered on the edges of the war, two colossi who hesitated to interfere directly for fear they would have to come to grips with each other.

The situation made the "Brinksmanship" of former Secretary Dulles look as safe as loafing in an easy-chair.

And the bureaucratic and legislative forces of the United States Government had reacted in a fairly predictable manner. The "security" guards around scientific research, which had been gradually diminishing towards the vanishing point, had suddenly been re-imposed—this time, even more stringently and rigidly than ever before.

Coupled with this was another force—apparently unrelated—which acted to tie in with the Federal security regulations. The juvenile delinquent gangs had begun to realize the value of science. Teen-age hoodlums armed with homemade pistols were dangerous enough in the Fifties; add aimed rockets and remote-control bombs to their armories, and you have an almost uncontrollable situation. Something had to be done, and various laws controlling the sale of scientific apparatus had been passed by the fifty states. And—as with their liquor and divorce laws—no two of the states had the same set of laws, and no one of them was without gaping flaws.

By the time the off-again-on-again wars in Europe had been stilled by the combined pressure of the United Nations—in which the United States and the Soviet Union co-operated wholeheartedly, working together in a way they had not done for over twenty years—the "scientific control laws" in the United States had combined to make scientific research almost impossible for the layman, and a matter of endless red tape, forms-in-octuplicate, licenses, permits, investigations, delays, and confusion for the professional.

The answer, of course, was the black market. What bootlegging had done for the average citizen in the Twenties, the black market was doing for scientists fifty years later.

The trouble was that, unlike the Volstead Act, the scientific prohibitions aroused no opposition from the man in the street. Indeed, he rather approved of them. He needed and wanted the products of scientific research, but he had a vague fear of the scientist—the "egghead." To his way of thinking, the laws were cleverly-designed restrictions promulgated by that marvelous epitome of humanity, the common man, to keep the mysterious scientists from meddling with things they oughtn't to.

The result was that the Latin American countries went into full swing, producing just those items which North American scientists couldn't get their hands on, because the laws stayed on the books. During the next ten years, they were modified slightly, but only very slightly; but the efforts to enforce them became more and more lax. By the time the late Seventies and early Eighties rolled around, the black marketeers were doing very nicely, thank you, and any suggestion from scientists that the laws should be modified was met with an intensive counterpropaganda effort by the operators of the black market.

Actually, the word "operators" is a misnomer. It was known by the authorities at the time that there was only one ring operating; the market was too limited to allow for the big-time operations carried on by the liquor smugglers and distillers of half a century before.

Sam Bending naturally was forced to deal with the black market, just as everyone else engaged in research was; it was, for instance, the only source for a good many technical publications which had been put on the Restricted List. Sam wasn't as dependent on them as college and university research men were, simply because he was engaged in industrial work, which carried much higher priorities than educational work did.

Sam, however, was fed up with the whole mess, and would have given his eyeteeth to clear up the whole stupid farce.

Irritated by every petty distraction at his office, Sam Bending finally gave up trying to cope with anything for the rest of the day. At three in the afternoon, he told his secretary that he was going home, jammed his hat on his head, and went out to his car.

He got in, turned the switch, and listened to the deep hum of the electric motors inside. Somehow, it made him feel so good that the irritations of the day lessened a great deal. He grinned.

Power Utilities hadn't even thought of this hiding place. The Converter in the rear of the car gave the vehicle far more power than it needed, but the extra juice came in handy sometimes. The driving motors wouldn't take the full output of the generators, of course; the Converter
