Suddenly, he reached out and grabbed Peer by one ankle, then dragged him off the step. Peer hit the ground on his arse with a jarring thud. His first instinct was to freeze the clone's power to interact with him, but he stopped himself. He was in no danger -- and if his twin wanted to burn off some aggression on his brother-creator, he could take it. They were evenly matched, after all.

Two minutes later, Peer was lying with his face in the dirt and his arms pinned behind his back. The clone kneeled over him, breathless but triumphant.

Peer said, "All right, you win. Now get off me -- or I'll double my height, put on forty kilograms, and get up and flatten you."

The clone said, "Do you know what we should do?"

"Shake hands and say goodbye."

"Toss a coin."

"For what?"

The clone laughed. "What do you think?"

"You said you were happy to go."

"I am. But so should you be. I say we toss a coin. If I win, we swap key numbers."

"That's illegal!"

"Illegal!" The clone was contemptuous. "Listen to the Solipsist Nation Copy invoke the laws of the world! It's easily done. The software exists. All you have to do is agree."

Talking was difficult; Peer spat out sand, but there was a seed of some kind caught between his teeth which he couldn't dislodge. He felt a curious reluctance to "cheat," though -- to remove the seed from his mouth, or the clone from his back. It had been so long since he'd been forced to endure the slightest discomfort that the novelty seemed to outweigh the inconvenience.

He said, "All right. I'll do it"

And if he lost? But why should he fear that? Five minutes ago, he'd been prepared to give rise to -- to become -- the clone who'd stow away.

They created the coin together, the only way to ensure that it was subject to no hidden influences. The reality editor they jointly invoked offered a standard object ready-made for their purpose, which they decorated as a one-pound coin. The physics of flipping a real coin wouldn't come into it; any Copy could easily calculate and execute a flick of the thumb leading to a predetermined outcome. The result would be controlled by a random number generator deep in the hidden layers of the operating system.

Peer said, "I toss, you call" -- at exactly the same time as the clone. He laughed. The clone smiled faintly. Peer was about to defer, then decided to wait. A few seconds later, he said, alone, "All right, you toss."

As the coin went up, Peer thought about encasing it in a second object, an invisibly thin shell under his control alone -- but the long list of attributes of the fair coin probably included crying foul if its true faces were concealed. He shouted "Heads!" just before the thing hit the dirt.

The two of them fell to their hands and knees, almost bumping heads. A hen approached; Peer shooed it away with a backward kick.

President Kinnock, in profile, glinted in the dust.

The clone met his eyes. Peer did his best not to look relieved -- short of severing ties with his body. He tried to read the clone's expression, and failed; all he saw was a reflection of his own growing numbness. Pirandello had said it was impossible to feel any real emotion while staring into a mirror. Peer decided to take that as a good sign. They were still one person, after all -- and that was the whole point.

The clone rose to his feet dusting off his knees and elbows. Peer took a hologram-embossed library card from the back pocket of his jeans and handed it over; it was an icon for a copy of all the environments, customized utilities, bodies, memories and other data he'd accumulated since his resurrection.

The clone said, "Don't worry about me -- or Kate. We'll look after each other. We'll be happy." As he spoke, he morphed smoothly into an older body.

Peer said, "Ditto." He reached up and shook the young man's hand. Then he summoned one of his control windows and froze the clone, leaving the motionless body visible as an icon for the snapshot file. He shrunk it to a height of a few centimeters, flattened it into a two-dimensional postcard, and wrote on the back: to malcolm carter.

Then he walked down the road a kilometer to one of Kate's little touches, a postbox marked us mail, and dropped the postcard in.

(Remit not paucity)

JUNE 2051

The anaesthetist said, "Count backward from ten."

Maria said, "Ten."

She dreamed of arriving on Francesca's doorstep with a suitcase full of money. As she walked down the hall behind her mother, the case fell open, and hundred-dollar bills fluttered out and filled the air like confetti.

Francesca turned to her, radiant with health. She said tenderly, "You shouldn't have, my darling. But I understand. You can't take it with you."

Maria laughed. "You can't take it with you."

Her father was in the living room, dressed for his wedding day, although not as young. He beamed and held out his arms to Maria. His parents, and Francesca's parents, stood behind him -- and as Maria approached, she saw from on high that behind her grandparents were cousins and aunts, great-grandparents and great-aunts, row after row of relatives and ancestors, stretching back into the depths of the house, laughing and chattering. The money had brought them all back to life. How could she have been so selfish as to think of denying them this grand reunion?

Maria threaded her way through the crowd, greeting people she'd never known existed. Handsome, dark-eyed seventh cousins kissed her hand and whispered compliments in a beautiful dialect she didn't understand. Veiled widows in elegant black dresses stood arm-in-arm with their resurrected husbands. Children weaved between the adults' legs, stealing food by the handful and cramming it into their mouths on the run.

The clinic's neurologist turned out to be a distant relative. Maria cupped her hands to the woman's ear and shouted over the noise of the party: "Have I been scanned yet? Will my Copy remember any of this?" The neurologist explained that the scan only captured memories laid down permanently as changes in synaptic strengths; the fleeting electrochemistry of this dream would be lost forever. She added cryptically, "Lost to whoever's not having it."

Maria felt herself waking. Suddenly afraid that she might be the Copy, she struggled to remain in the dream -- as if she could force her way back through the crowd, back through the plot, and leave by a different exit. But the scene grew vague and unconvincing; she could feel the heavy presence of her waking body: her aching shoulders, her swollen tongue.

She opened her eyes. She was alone in the Landau Clinic's cheerfully decorated recovery room; she'd been wheeled through for a patient's-eye view before being given the anesthetic, so she'd know exactly what to expect. It took a few seconds for the truths of the dream to fade, though. Her father was dead. Her grandparents were dead. There'd been no grand reunion. There never would be.

As for the Copy . . . her scan file didn't even exist, yet; the raw tomographic data would take hours to be processed into a high-resolution anatomical map. And she could still change her mind and keep the results out of Durham's hands altogether. He'd paid the clinic for the scan, but if she refused to hand over the file there'd be nothing he could do about it.

The recovery room was softly lit, lined with odorless blue and orange flowers. Maria closed her eyes. If Durham's logic meant anything, raw tomographic data could probably process itself, find itself conscious, as easily as any Copy who'd been chopped up and run at random. There was no need for a finished scan file.
