Peer laughed. "Then why stow away at all? If that happens, there'll be nothing to fear from weather control."

"Because there might not have been any breakthrough. The only thing that's certain is that some of the wealthiest -- and best-informed -- Copies have decided that it's worth going into this . . . sanctuary. And I've got the chance to go with them."

Peer was silent for a while. Finally, he asked, "So are you moving -- or cloning yourself?"

"Cloning."

He could have concealed his relief, easily -- but he didn't. He said, "I'm glad. I would have missed you."

"And I'd have missed you. I want you to come with me."

"You want -- ?"

Kate leaned toward him. "Carter has said he'll include you -- and your baggage -- for another fifty percent. Clone yourself and come with me. I don't want to lose you -- either of me."

Peer felt a rush of excitement -- and fear. He took a snap-shot of the emotion, then said, "I don't know. I've never --"

"A second version, running on the most secure hardware on the planet. That's not surrendering to outside -- it's just finally gaining some true independence."

"Independence? What if these Copies get bored with Carter's city and decide to trash it -- trade it in for something new?"

Kate was unfazed. "That's not impossible. But there are no guarantees on the public networks, either. This way, at least you have a greater chance that one version will survive."

Peer tried to imagine it. "Stowaways. No communications. Just us, and whatever software we bring."

"You're Solipsist Nation, aren't you?"

"You know I am. But . . . I've never run a second version before. I don't know how I'll feel about that, after the split."

How who will feel about it?

Kate bent over and picked up his heart. "Having a second version won't bother you." She fixed her new gray eyes on him. "We're running at a slowdown of sixty-seven. Carter will be delivering his city to Durham, six real-time months from now. But who knows when Operation Butterfly will flat-line us again? So you don't have long to decide."

Peer continued to show Kate his body sitting in the chair, thinking it over, while in truth he rose to his feet and walked across the room, escaping her formidable gaze.

Who am I? Is this what I want?

He couldn't concentrate. He manually invoked a menu on one of the control screens, an array of a dozen identical images: a nineteenth-century anatomical drawing of the brain, with the surface divided into regions labeled with various emotions and skills. Each icon represented a package of mental parameters: snapshots of previous states of mind, or purely synthetic combinations.

Peer hit the icon named clarity.

In twelve short real-time years as a Copy, he'd tried to explore every possibility, map out every consequence of what he'd become. He'd transformed his surroundings, his body, his personality, his perceptions -- but he'd always owned the experience himself. The tricks he'd played on his memory had added, never erased -- and whatever changes he'd been through, there was always only one person, in the end, taking responsibility, picking up the pieces. One witness, unifying it all.

The truth was, the thought of finally surrendering that unity made him dizzy with fear. It was the last vestige of his delusion of humanity. The last big lie.

And as Daniel Lebesgue, founder of Solipsist Nation, had written: "My goal is to take everything which might be revered as quintessentially human . . . and grind it into dust."

He returned to his seated body, and said, "I'll do it."

Kate smiled, raised his beating heart to her lips, and gave it a long, lingering kiss.

JUNE 2045

Paul woke without any confusion. He dressed and ate, trying to feel optimistic. He'd demonstrated his willingness to cooperate; now it was time to ask for something in return. He walked into the study, switched on the terminal, and called his own number. The djinn answered at once.

Paul said, "I'd like to talk to Elizabeth."

Squeak. "That's not possible."

"Not possible? Why don't you just ask her?"

Squeak. "I can't do that. She doesn't even know you exist."

Paul stared at him coldly. "Don't lie to me, it's a waste of time. As soon as I had a Copy who survived, I was going to explain everything --"

Squeak. The djinn said drily, "Or so we thought."

Paul's certainty wavered. "You're telling me that your great ambition is finally being fulfilled -- and you haven't even mentioned it to the one woman . . . ?"

Squeak. Durham's face turned to stone. "I really don't wish to discuss it. Can we get on with the experiment, please?"

Paul opened his mouth to protest -- and then found he had nothing to say. All his anger and jealousy suddenly dissipated into . . . embarrassment. It was as if he'd just come to his senses from a daydream, an elaborate fantasy of a relationship with someone else's lover. Paul and Elizabeth. Elizabeth and Paul. What happened between them was none of his business. Whatever his memories suggested, that life wasn't his to live anymore.

He said, "Sure, let's get on with the experiment. Time is just rushing by. You must have turned forty-five . . . what, a day ago? Many happy returns."

Squeak. "Thanks -- but you're wrong. I took some shortcuts while you were asleep: I shut down part of the model -- and cheated on most of the rest. It's only the fourth of June; you got six hours' sleep in ten hours' real time. Not a bad job, I thought."

Paul was outraged. "You had no right to do that!"

Squeak. Durham sighed. "Be practical. Ask yourself what you'd have done in my place."

"It's not a joke!"

Squeak. "So you slept without a whole body. I cleaned a few toxins out of your blood at a non-physiological rate." The djinn seemed genuinely puzzled. "Compared to the experiments, that's nothing. Why should it bother you? You've woken up in exactly the same condition as you'd be in if you'd slept in the normal way."

Paul caught himself. He didn't want to explain how vulnerable it made him feel to have someone reach through the cracks in the universe and relieve him of unnecessary organs while he slept. And the less the bastard knew about his Copy's insecurities, the better -- he'd only exploit them.

He said, "It bothers me because the experiments are worthless if you're going to intervene at random. Precise, controlled changes -- that's the whole point. You have to promise me you won't do it again."

Squeak. "You're the one who was complaining about waste. Someone has to think about conserving our dwindling resources."

"Do you want me to keep on cooperating? Or do you want to start everything again from scratch?"

Squeak. The djinn said mildly, "All right, you don't have to threaten me. You have my word: no more ad hoc intervention."

"Thank you."

Conserving our dwindling resources? Paul had been trying hard not to think about money. What would the djinn do when he could no longer afford to keep him running -- if Paul chose not to bale out once the experiments were over? Store a snapshot of the model, of course, until he could raise the cash flow to start it up again. In the long term, set up a trust fund; it would only have to earn enough to run him part-time, at first: keep him in touch with the world, stave off excessive culture shock . . . until the technology became cheap enough to let him live continuously.
