David paced the floor, glass 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! Fauré! How do you feel about this thing now? Are you still game?"

Both men seemed a little dazed, but Fauré 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!"

"I'd hardly call it immortality," said Hudson drily, "since, as I understand it, SDE does not kill disease entities, nor ward off bullets or the disintegrating nuclear shaft of the needler—as we will very likely find out before very long. But what do we do now? When people see these two girls together, it won't be an hour before Marley hears about it."

David spoke up with a new authority. "He must not hear about it. I know how poorly equipped I am to handle this situation, but since I created it, I must assume responsibility, and I have made my plans.

"First, you, Tanya. Try to realize that if the Leader finds out that I have this secret of keeping youth, he will want it for himself. Nobody in Menial, nobody in Office, nobody in Research—almost nobody at all—will be allowed to benefit from it. Marley will use it as a special reward for certain Rulers, and he will try to keep its very existence a secret so that people in general will not be envious or rebellious. That means that he will have to get rid of you."

"Get rid of me? But I haven't done any harm!"
