The second day she was there a delivery van pulled up outside, and two guys started unloading a king-size waterbed. She laughed and laughed when she saw my face.

"Listen, you're not using Kluge's computers to-"

"Relax, Yank. How'd you think I could afford a Ferrari?"

"I've been curious."

"If you're really good at writing software you can make a lot of money. I own my own company. But every hacker picks up tricks here and there. I used to run a few Kluge scams, myself."

"But not anymore?"

She shrugged. "Once a thief, always a thief, Victor. I told you I couldn't make ends meet selling my bod."

Lisa didn't need much sleep.

We got up at seven, and I made breakfast every morning. Then we would spend an hour or two working in the garden.

She would go to Kluge's and I'd bring her a sandwich at noon, then drop in on her several times during the day. That was for my own peace of mind; I never stayed more than a minute. Sometime during the afternoon I would shop or do household chores, then at seven one of us would cook dinner. We alternated. I taught her "American" cooking, and she taught me a little of everything. She complained about the lack of vital ingredients in American markets. No dogs, of course, but she claimed to know great ways of preparing monkey, snake, and rat. I never knew how hard she was pulling my leg, and didn't ask.

After dinner she stayed at my house. We would talk, make love, bathe.

She loved my tub. It is about the only alteration I have made in the house, and my only real luxury. I put it in- having to expand the bathroom to do so-in 1975, and never regretted it. We would soak for twenty minutes or an hour, turning the jets and bubblers on and off, washing each other; giggling like kids. Once we used bubble bath and made a mountain of suds four feet high, then destroyed it, splashing water all over the place. Most nights she let me wash her long black hair.

She didn't have any bad habits-or at least none that clashed with mine. She was neat and clean, changing her clothes twice a day and never so much as leaving a dirty glass on the sink. She never left a mess in the bathroom. Two glasses of wine was her limit.

I felt like Lazarus.

Osborne came by three times in the next two weeks. Lisa met him at Kluge's and gave him what she had learned. It was getting to be quite a list.

"Kluge once had an account in a New York bank with nine trillion dollars in it," she told me after one of Osborne's visits. "I think he did it just to see if he could. He left it in for one day, took the interest and fed it to a bank in the Bahamas, then destroyed the principal. Which never existed anyway."

In return, Osborne told her what was new on the murder investigation-which was nothing-and on the status of Kluge's property, which was chaotic. Various agencies had sent peo­ple out to look the place over. Some FBI men came, wanting to take over the investigation. Lisa, when talking about com­puters, had the power to cloud men's minds. She did it first by explaining exactly what she was doing, in terms so ab­struse that no one could understand her. Sometimes that was enough. If it wasn't, if they started to get tough, she just moved out of the driver's seat and let them try to handle Kluge's contraption. She let them watch in horror as dragons leaped out of nowhere and ate up all the data on a disc, then printed "You Stupid Putz!" on the screen.

"I'm cheating them," she confessed to me. "I'm giving them stuff I know they're gonna step in, because I already stepped in it myself. I've lost about forty percent of the data Kluge had stored away. But the others lose a hundred per­cent. You ought to see their faces when Kluge drops a logic bomb into their work. That second guy threw a three thou­sand dollar printer clear across the room. Then tried to bribe me to be quiet about it."

When some federal agency sent out an expert from Stan­ford, and he seemed perfectly content to destroy everything in sight in the firm belief that he was bound to get it right sooner or later, Lisa showed him how Kluge entered the IRS main computer in Washington and neglected to mention how Kluge had gotten out. The guy tangled with some watchdog pro­gram. During his struggles, it seemed he had erased all the tax records from the letter S down into the W's. Lisa let him think that for half an hour.

"I thought he was having a heart attack," she told me. "All the blood drained out of his face and he couldn't talk. So I showed him where I had-with my usual foresight- arranged for that data to be recorded, told him how to put it back where he found it, and how to pacify the watchdog. He couldn't get out of that house fast enough. Pretty soon he's gonna realize you can't destroy that much information with anything short of dynamite because of the backups and the limits of how much can be running at any one time. But I don't think he'll be back."

"It sounds like a very fancy video game," I said.

"It is, in a way. But it's more like Dungeons and Dragons. It's an endless series of closed rooms with dangers on the other side. You don't dare take it a step at a time. You take it a hundredth of a step at a time. Your questions are like, 'Now this isn't a question, but if it entered my mind to ask

this question-which I'm not about to do-concerning what might happen if I looked at this door here-and I'm not touching it, I'm not even in the next room-what do you suppose you might do?' And the program crunches on that, decides if you fulfilled the conditions for getting a great big cream pie in the face, then either throws it or allows as how it might just move from step A to step A Prime. Then you say, 'Well, maybe I am looking at that door.' And sometimes the program says 'You looked, you looked, you dirty crook!' And the fireworks start."

Silly as all that sounds, it was very close to the best explanation she was ever able to give me about what she was doing.

"Are you telling everything, Lisa?" I asked her.

"Well, not everything. I didn't mention the four cents."

Four cents? Oh my god.

"Lisa, I didn't want that, I didn't ask for it, I wish he'd never-"

"Calm down, Yank. It's going to be all right."

"He kept records of all that, didn't he?"

"That's what I spend most of my time doing. Decoding his records."

"How long have you known?"

"About the seven hundred thousand dollars? It was in the first disc I cracked."

"I just want to give it back."

She thought that over, and shook her head.

"Victor, it'd be more dangerous to get rid of it now than it would be to keep it. It was imaginary money at first. But now it's got a history. The IRS thinks it knows where it came from. The taxes are paid on it. The State of Delaware is convinced that a legally chartered corporation disbursed it. An Illinois law firm has been paid for handling it. Your bank has been paying you interest on it. I'm not saying it would be impossible to go back and wipe all that out, but I wouldn't like to try. I'm good, but I don't have Kluge's touch."

"How could he do all that? You say it was imaginary money. That's not the way I thought money worked. He could just pull it out of thin air?''

Lisa patted the top of her computer console, and smiled at me.

"This is money, Yank," she said, and her eyes glittered.

At night she worked by candlelight so she wouldn't disturb me. That turned out to be my downfall. She typed by touch, and needed the candle only to locate software.

So that's how I'd go to sleep every night, looking at her slender body bathed in the glow of the candle. I was always reminded of melting butter dripping down a roasted ear of corn. Golden light on golden skin.

Ugly, she had called herself. Skinny. It was true she was thin. I could see her ribs when she sat with her back impossi­bly straight, her tummy sucked in, her chin up. She worked in the nude these days, sitting in lotus position. For long periods she would not move, her hands lying on her thighs, then she would poise, as if to pound the keys. But her touch was light, almost silent. It looked more like yoga than pro­gramming. She said she went into a meditative state for her best work.
