"What'll we do?" the driver said finally. "We have no instructions past this."

"Take him to the station. We can't do any more questioning here." Beyond the cruiser, men and women hurried along the sidewalk. The streets were choked with cruisers, workers going to their homes in the country.

"Jennings, why don't you answer us? What's the matter with you? There's no reason why you can't tell us a couple of simple things like that. Don't you want to cooperate with your Government? Why should you conceal informa­tion from us?"

"I'd tell you if I knew."

The officer grunted. No one spoke. Presently the cruiser drew up before a great stone building. The driver turned the motor off, removing the control cap and putting it in his pocket. He touched the door with a code key, releas­ing the magnetic lock.

"What shall we do, take him in? Actually, we don't --"

"Wait." The driver stepped out. The other two went with him, closing and locking the doors behind them. They stood on the pavement before the Secu­rity Station, talking.

Jennings sat silently, staring down at the floor. The SP wanted to know about Rethrick Construction. Well, there was nothing he could tell them. They had come to the wrong person, but how could he prove that? The whole thing was impossible. Two years wiped clean from his mind. Who would believe him? It seemed unbelievable to him, too.

His mind wandered, back to when he had first read the ad. It had hit home, hit him direct. Mechanic wanted, and a general outline of the work, vague, indirect, but enough to tell him that it was right up his line. And the pay! Interviews at the Office. Tests, forms. And then the gradual realization that Rethrick Construction was finding all about him while he knew nothing about them. What kind of work did they do? Construction, but what kind? What sort of machines did they have? Fifty thousand credits for two years...

And he had come out with his mind washed clean. Two years, and he remembered nothing. It took him a long time to agree to that part of the contract. But he had agreed.

Jennings looked out the window. The three officers were still talking on the sidewalk, trying to decide what to do with him. He was in a tough spot. They wanted information he couldn't give, information he didn't know. But how could he prove it? How could he prove that he had worked two years and come out knowing no more than when he had gone in! The SP would work him over. It would be a long time before they'd believe him, and by that time --

He glanced quickly around. Was there any escape? In a second they would be back. He touched the door. Locked, the triple-ring magnetic locks. He had worked on magnetic locks many times. He had even designed part of a trigger core. There was no way to open the doors without the right code key. No way, unless by some chance he could short out the lock. But with what?

He felt in his pockets. What could he use? If he could short the locks, blow them out, there was a faint chance. Outside, men and women were swarming by, on their way home from work. It was past five; the great office buildings were shutting down, the streets were alive with traffic. If he once got out they wouldn't dare fire. If he could get out.

The three officers separated. One went up the steps into the Station building. In a second the others would reenter the cruiser. Jennings dug into his pocket, bringing out the code key, the ticket stub, the wire. The wire! Thin wire, thin as human hair. Was it insulated? He unwound it quickly. No.

He knelt down, running his fingers expertly across the surface of the door. At the edge of the lock was a thin line, a groove between the lock and the door. He brought the end of the wire up to it, delicately maneuvering the wire into the almost invisible space. The wire disappeared an inch or so. Sweat rolled down Jennings' forehead. He moved the wire a fraction of an inch, twisting it. He held his breath. The relay should be --

A flash.

Half blinded, he threw his weight against the door. The door fell open, the lock fused and smoking. Jennings tumbled into the street and leaped to his feet. Cruisers were all around him, honking and sweeping past. He ducked behind a lumbering truck, entering the middle lane of traffic. On the sidewalk he caught a momentary glimpse of the SP men starting after him.

A bus came along, swaying from side to side, loaded with shoppers and workers. Jennings caught hold of the back rail, pulling himself up onto the platform. Astonished faces loomed up, pale moons thrust suddenly at him. The robot conductor was coming toward him, whirring angrily.

"Sir --" the conductor began. The bus was slowing down. "Sir, it is not allowed --"

"It's all right," Jennings said. He was filled, all at once, with a strange elation. A moment ago he had been trapped, with no way to escape. Two years of his life had been lost for nothing. The Security Police had arrested him, demanding information he couldn't give. A hopeless situation! But now things were beginning to click in his mind.

He reached into his pocket and brought out the bus token. He put it calmly into the conductor's coin slot.

"Okay?" he said. Under his feet the bus wavered, the driver hesitating. Then the bus resumed pace, going on. The conductor turned away, its whirrs subsiding. Everything was all right. Jennings smiled. He eased past the standing people, looking for a seat, some place to sit down. Where he could think.

He had plenty to think about. His mind was racing.

The bus moved on, flowing with the restless stream of urban traffic. Jen­nings only half saw the people sitting around him. There was no doubt of it: he had not been swindled. It was on the level. The decision had actually been his. Amazingly, after two years of work he had preferred a handful of trinkets instead of fifty thousand credits. But more amazingly, the handful of trinkets were turning out to be worth more than the money.

With a piece of wire and a bus token he had escaped from the Security Police. That was worth plenty. Money would have been useless to him once he disappeared inside the great stone Station. Even fifty thousand credits wouldn't have helped him. And there were five trinkets left. He felt around in his pocket. Five more things. He had used two. The others -- what were they for? Something as important?

But the big puzzle: how had he -- his earlier self -- known that a piece of wire and a bus token would save his life?" He had known, all right. Known in advance. But how? And the other five. Probably they were just as precious, or would be.

The he of those two years had known things that he did not know now, things that had been washed away when the company cleaned his mind. Like an adding machine which had been cleared. Everything was slate-clean. What he had known was gone, now. Gone, except for seven trinkets, five of which were still in his pocket.

But the real problem right now was not a problem of speculation. It was very concrete. The Security Police were looking for him. They had his name and description. There was no use thinking of going to his apartment -- if he even still had an apartment. But where, then? Hotels? The SP combed them daily. Friends? That would mean putting them in jeopardy, along with him. It was only a question of time before the SP found him, walking along the street, eating in a restaurant, in a show, sleeping in some rooming house. The SP were everywhere.

Everywhere? Not quite. When an individual person was defenseless, a business was not. The big economic forces had managed to remain free, although virtually everything else had been absorbed by the Government. Laws that had been eased away from the private person still protected prop­erty and industry. The SP could pick up any given person, but they could not enter and seize a company, a business. That had been clearly established in the middle of the twentieth century.
