"Five days yet. Then this is what we'll do. Too bad Lanza is in the other camp, but there's you and me, and I think Hudson and Faure from Serology will come in with us. We'll need others--sociologists, anthropologists, psychologists--the most promising material from all Categories if we're to create a new society based on the prospect of immortality. But I'll see the first two and bring them to your apartment tomorrow night for Tanya's welcome-home party. I leave it to you to muzzle Leah."

"That won't do," said David. "I don't have a current Free Choice."

"But I have. Two, as a matter of fact, a reward for curing the insomnia of Leader Marley's wife. I choose to give a party, I choose tomorrow night, and I choose your apartment."

A knock rattled the door, and the watchguard thrust in his head. "How much longer is this here experiment going to take? Do you guys want to be reported?"

"Just finishing, Officer," called Karl. "You can leave the door open now."

"What a stink!" said the guard. "Thank G.o.d I'm in Military!"

It hardly seemed like a party, David thought. His guests were ill at ease, and their conversation labored, then stopped altogether when the Menial came into the library with a tray of gla.s.ses and niblets.

"Put them on the liquor cabinet, James," said David. "And that will be all. Enjoy yourself tonight."

The Menial put down the tray and then stooped to fumble with the lock.

"Let that alone! I've told you a thousand times not to monkey with my liquor cabinet!"

"Don't you want me to get out the ice cubes, Doctor?"

"I'll do it. You can go now."

"But are you sure you won't want me later in the evening, Doctor? Who's to serve the supper? Who's going to clear up afterward?"

"We'll manage. Don't worry about us."

James shuffled out of the room.

"I suppose that means _I'll_ manage," said Leah, with a self-pitying sigh. "I've noticed that whenever people decide to rough it and do without a Menial, they take it for granted the women will do the work, never the men--unless the women are still young and pretty. Well, at any rate, I'll have Tanya to help me. I still don't see why you wouldn't let me go to the Port to meet her, Dr. Wong."

"I just thought it would be more of a celebration if we had a surprise party all waiting for her to walk into. Dr. Haslam will bring her here directly from the Port, and here we all are, her old friends from the Inst.i.tute, waiting to welcome her home."

"I'd hardly say all," said Leah. "I'm the only person from Office that's here. And why have a party in your Library, Dr. Wong? Nothing here but books, books, books."

"Because I keep my liquor here, in the only room I have a right to lock up. My Menial is a good man, but he can't resist an opened bottle."

"Well, it's still a gloomy party."

David turned appealingly to his other guests, Hudson and Faure, but they only looked uncomfortable.

"Perhaps we need a drink." David unlocked the cupboard and picked up a bottle which he set down hastily when he heard voices in the hall. He hurried to the outer door and opened it a few inches to reveal the st.u.r.dy shoulders of the watchguard of the floor and, beyond him, Karl Haslam.

"Everything in order, Officer?" asked Karl.

"Your permit is in order, Dr. Haslam. A private party. Let me just check--yes, three guests have arrived, and you two make five. That all?

You have until midnight. But it beats me why you people in Research prefer a party without a watchguard, or why Leader Marley ever gives permission. Why, in all my years in Military, I've never been to an unwatched party, and I must say it never held us down any."

Karl laughed a little too forcedly. "I'll bet it didn't! But all Research people are a little peculiar. You must have noticed that yourself."

"Well--"

"And you know how generous Leader Marley is, and how kind he is to loyal citizens. He wants us to be happy, so he pampers us now and then."

"I guess he knows what he's doing, all right. Well, I'll check you out at twelve, then."

"Go on in, Tanya," said Karl.

They stepped into the apartment and David quietly closed the door.

"Hi, Sis," drawled Leah. "You made us wait long enough!" She walked toward the girl, hand outstretched, then stopped with a gasp of disbelief.

Tanya's red hair was still brilliant and gleaming, her creamy skin unlined, and her full red lips curved up into a friendly smile as she leaned forward for a sisterly kiss. But Leah jerked away and glared with anger.

A puzzled frown creased Tanya's lovely white forehead.

"What's the matter, Leah? Aren't you glad to see me? You look so strange, as though you'd been terribly ill!"

Leah shook her head, tears of rage gathering in her pale eyes. "I'm okay," she whispered. "It's you. You haven't changed. I have. You're still young, you're pretty, _you're just the way I used to be_!" She whirled to face David, her voice choking.

"What have you done to her, Dr. Wong?"

The four men in the room were all staring at the sisters, scarcely believing what they saw, although they had all been prepared for the contrast. The twin sisters were no longer twins. One had retained her youth; the other was faded, aging.

"This is awful," Haslam muttered. "Absolutely ghastly." He put a comforting hand on Leah's shoulder, and with a deep sob she hid her face against him and cried.

Hudson and Faure could not take their eyes from Tanya, and David leaned against the wall to stop his trembling.

"Sit down, all of you," he said. "First we'll have a drink. I'm sure we all need it. Then we'll face--what has to be faced."

An hour later, they had achieved a calmness, of sorts. They had given up some of their normal sobriety to achieve the calm, but they were grateful to the drug for cushioning the shock.

David paced the floor, gla.s.s in hand, talking rapidly as he finished his long explanation.

"So you see what happened," he said. "When I began the experiment, I had no idea how staggering the results might be. That is, I knew in my mind, but I never imagined the _realness_ of what would happen. I thought of it as just an experiment."

Leah sniffed, her resentment somewhat dulled by drink. "So I was just an experiment! Don't you ever think about people's feelings? I know I'm not as good as you are; I'm only Office, but I'm human."

Karl patted her hand. "Of course you are, Leah. But that is one of the defects of people in Research--they forget about human emotions." He looked up sternly at David. "They go ahead with their experiments, and hang the consequences. If Dr. Wong had had any sense, he would never have kept this a secret for ten years, and we might have had ten years to prepare ourselves for such a responsibility. Instead, we have only a few days or, at most, weeks. Hudson! Faure! How do you feel about this thing now? Are you still game?"

Both men seemed a little dazed, but Faure pulled himself together, speaking slowly, like a man in a dream.

"We're with you. It's still hard to believe: we've got immortality!"
