"The whole works at once?"

"Fifty thousand credits."

Jennings smiled. He felt a little better, now that the sum had been spoken aloud. Maybe it wasn't so bad, after all. Almost like being paid to sleep. But he was two years older; he had just that much less to live. It was like selling part of himself, part of his life. And life was worth plenty, these days. He shrugged. Anyhow, it was in the past.

"We're almost there," the older man said. The robot pilot dropped the cruiser down, sinking toward the ground. The edge of New York City became visible below them. "Well, Jennings, I may never see you again." He held out his hand. "It's been a pleasure working with you. We did work together, you know. Side by side. You're one of the best mechanics I've ever seen. We were right in hiring you, even at that salary. You paid us back many times -- although you don't realize it."

"I'm glad you got your money's worth."

"You sound angry."

"No. I'm just trying to get used to the idea of being two years older."

Rethrick laughed. "You're still a very young man. And you'll feel better when she gives you your pay."

They stepped out onto the tiny rooftop field of the New York office build­ing. Rethrick led him over to an elevator. As the doors slid shut Jennings got a mental shock. This was the last thing he remembered, this elevator. After that he had blacked out.

"Kelly will be glad to see you," Rethrick said, as they came out into a lighted hall. "She asks about you, once in a while."

"Why?"

"She says you're good-looking." Rethrick pushed a code key against a door. The door responded, swinging wide. They entered the luxurious office of Rethrick Construction. Behind a long mahogany desk a young woman was sitting, studying a report.

"Kelly," Rethrick said, "look whose time finally expired."

The girl looked up, smiling. "Hello, Mr. Jennings. How does it feel to be back in the world?"

"Fine." Jennings walked over to her. "Rethrick says you're the paymaster."

Rethrick clapped Jennings on the back. "So long, my friend. I'll go back to the plant. If you ever need a lot of money in a hurry come around and we'll work out another contract with you."

Jennings nodded. As Rethrick went back out he sat down beside the desk, crossing his legs. Kelly slid a drawer open, moving her chair back. "All right. Your time is up, so Rethrick Construction is ready to pay. Do you have your copy of the contract?"

Jennings took an envelope from his pocket and tossed it on the desk. "There it is."

Kelly removed a small cloth sack and some sheets of handwritten paper from the desk drawer. For a time she read over the sheets, her small face intent.

"What is it?"

"I think you're going to be surprised." Kelly handed him his contract back. "Read that over again."

"Why?" Jennings unfastened the envelope.

"There's an alternate clause. 'If the party of the second part so desires, at any time during his time of contract to the aforesaid Rethrick Construction Company --' "

" 'If he so desires, instead of the monetary sum specified, he may choose instead, according to his own wish, articles or products which, in his own opinion, are of sufficient value to stand in lieu of the sum --' "

Jennings snatched up the cloth sack, pulling it open. He poured the con­tents into his palm. Kelly watched.

"Where's Rethrick?" Jennings stood up. "If he has an idea that this --"

"Rethrick has nothing to do with it. It was your own request. Here, look at this." Kelly passed him the sheets of paper. "In your own hand. Read them. It was your idea, not ours. Honest." She smiled up at him. "This happens every once in a while with people we take on contract. During their time they decide to take something else instead of money. Why, I don't know. But they come out with their minds clean, having agreed --"

Jennings scanned the pages. It was his own writing. There was no doubt of it. His hands shook. "I can't believe it. Even if it is my own writing." He folded up the paper, his jaw set. "Something was done to me while I was back there. I never would have agreed to this."

"You must have had a reason. I admit it doesn't make sense. But you don't know what factors might have persuaded you, before your mind was cleaned. You aren't the first. There have been several others before you."

Jennings stared down at what he held in his palm. From the cloth sack he had spilled a little assortment of items. A code key. A ticket stub. A parcel receipt. A length of fine wire. Haifa poker chip, broken across. A green strip of cloth. A bus token.

"This, instead of fifty thousand credits," he murmured. "Two years..."

He went out of the building, onto the busy afternoon street. He was still dazed, dazed and confused. Had he been swindled? He felt in his pocket for the little trinkets, the wire, the ticket stub, all the rest. That, for two years of work! But he had seen his own handwriting, the statement of waiver, the request for the substitution. Like Jack and the Beanstalk. Why? What for? What had made him do it?

He turned, starting down the sidewalk. At the corner he stopped for a surface cruiser that was turning.

"All right, Jennings. Get in."

His head jerked up. The door of the cruiser was open. A man was kneel­ing, pointing a heat-rifle straight at his face. A man in blue-green. The Secu­rity Police.

Jennings got in. The door closed, magnetic locks slipping into place behind him. Like a vault. The cruiser glided off down the street. Jennings sank back against the seat. Beside him the SP man lowered his gun. On the other side a second officer ran his hands expertly over him, searching for weapons. He brought out Jenning's wallet and the handful of trinkets. The envelope and contract.

"What does he have?" the driver said.

"Wallet, money. Contract with Rethrick Construction. No weapons." He gave Jennings back his things.

"What's this all about?" Jennings said.

"We want to ask you a few questions. That's all. You've been working for Rethrick?"

"Yes."

"Two years?"

"Almost two years."

"At the Plant?"

Jennings nodded. "I suppose so."

The officer leaned toward him. "Where is that Plant, Mr. Jennings. Where is it located?"

"I don't know."

The two officers looked at each other. The first one moistened his lips, his face sharp and alert. "You don't know? The next question. The last. In those two years, what kind of work did you do? What was your job?"

"Mechanic. I repaired electronic machinery."

"What kind of electronic machinery?"

"I don't know." Jennings looked up at him. He could not help smiling, his lips twisting ironically. "I'm sorry, but I don't know. It's the truth."

There was silence.

"What do you mean, you don't know? You mean you worked on machinery for two years without knowing what it was? Without even knowing where you were?"

Jennings roused himself. "What is all this? What did you pick me up for? I haven't done anything. I've been --"

"We know. We're not arresting you. We only want to get information for our records. About Rethrick Construction. You've been working for them, in their Plant. In an important capacity. You're an electronic mechanic?"

"Yes."

"You repair high-quality computers and allied equipment?" The officer consulted his notebook. "You're considered one of the best in the country, according to this."

Jennings said nothing.

"Tell us the two things we want to know, and you'll be released at once. Where is Rethrick's Plant? What kind of work are they doing? You serviced their machines for them, didn't you? Isn't that right? For two years."

"I don't know. I suppose so. I don't have any idea what I did during the two years. You can believe me or not." Jennings stared wearily down at the floor.
