"When you already count on him, then he's ready. When his commitment and loyalty are firm, when the goals of the Second Foundation are already in his heart, when he acts them out in his life, then he's ready."

There was a finality in Hari's tone. The conversation was nearly over.

"By the way, Hari, you were right. No one has even questioned the omission of any important psychohistorical data from the Foundation library on Terminus."

"Of course not. Academics never look outside their own discipline. That's another reason why I'm glad Leyel isn't going. He would notice that the only psychologist we're sending is Bor Alurin. Then I'd have to explain more to him than I want. Give my love to Deet, Chanda. Tell her that her test case is going very well. She'll end up with a husband and a community of scientists of the mind."

"Artists. Wizards. Demigods."

"Stubborn misguided women who don't know science when they're doing it. All in the Imperial Library. Till next time, Chanda."

If Deet had asked him about his interview with Hari, if she had commiserated with him about Hari's refusal, his resentment of her might have been uncontainable, he might have lashed out at her and said something that could never be forgiven.

Instead, she was perfectly herself, so excited about her work and so beautiful, even with her face showing all the sag and wrinkling of her sixty years, that all Leyel could do was fall in love with her again, as he had so many times in their years together.

"It's working beyond anything I hoped for, Leyel. I'm beginning to hear stories that I created months and years ago, coming back as epic legends. You remember the time I retrieved and extrapolated the accounts of the uprising at Misercordia only three days before the Admiralty needed them?"

"Your finest hour. Admiral Divart still talks about how they used the old battle plots as a strategic guideline and put down the Tellekers' strike in a single three-day operation without loss of a ship."

"You have a mind like a trap, even if you are old."

"Sadly, all I can remember is the, past."

"Dunce, that's all anyone can remember."

He prompted her to go on with her account of today's triumph. "It's an epic legend now?"

"It came back to me without my name on it, and bigger than life. As a reference.

Rinjy was talking with some young librarians from one of the inner provinces who were on the standard interlibrary tour, and one of them said something about how you could stay in the Imperial Library on Trantor all your life and never see the real world at all."

Leyel hooted. "Just the thing to say to Rinjy!"

"Exactly. Got her dander up, of course, but the important thing is, she immediately told them the story of how a librarian, all on her own, saw the similarity between the Misercordia uprising and the Tellekers' strike. She knew no one at the Admiralty would listen to her unless she brought them all the information at once. So she delved back into the ancient records and found them in deplorable shape-- the original data had been stored in glass, but that was forty-two centuries ago, and no one had refreshed the data. None of the secondary sources actually showed the battle plots or ship courses-- Misercordia had mostly been written about by biographers, not military historians--"

"Of course. It was Pol Yuensau's first battle, but he was just a pilot, not a commander--"

"I know you remember, my intrusive pet. The point is what Rinjy said about this mythical librarian."

"You."

"I was standing right there. I don't think Rinjy knew it was me, or she would have said something-- she wasn't even in the same division with me then, you know. What matters is that Rinjy heard a version of the story and by the time she told it, it was transformed into a magic hero tale. The prophetic librarian of Trantor."

"What does that prove? You are a magic hero."

"The way she told it, I did it all on my own initiative--"

"You did. You were assigned to do document extrapolation, and you just happened to start with Misercordia."

"But in Rinjy's version, I had already seen its usefulness with the Tellekers'

strike. She said the librarian sent it to the Admiralty and only then did they realize it was the key to bloodless victory."

"Librarian saves the Empire."

"Exactly."

"But you did."

"But I didn't mean to. And Admiralty requested the information-- the only really extraordinary thing was that I had already finished two weeks of document restoration--"

"Which you did brilliantly."

"Using programs you had helped design, thank you very much, O Wise One, as you indirectly praise yourself. It was sheer coincidence that I could give them exactly what they wanted within five minutes of their asking. But now it's a hero story within the community of librarians. In the Imperial Library itself, and now spreading outward to all the other libraries."

"This is so anecdotal, Deet. I don't see how you can publish this."

"Oh, I don't intend to. Except perhaps in the introduction. What matters to me is that it proves my theory. "

"It has no statistical validity."

"It proves it to me. I know that my theories of community formation are true. That the vigor of a community depends on the allegiance of its members, and the allegiance can be created and enhanced by the dissemination of epic stories."

"She speaks the language of academia. I should be writing this down, so you don't have to think up all those words again."

"Stories that make the community seem more important, more central to human life.

Because Rinjy could tell this story, it made her more proud to be a librarian, which increased her allegiance to the community and gave the community more power within her."

"You are possessing their souls."

"And they've got mine. Together our souls are possessing each other."

There was the rub. Deet's role in the library had begun as applied research-- joining the library staff in order to confirm her theory of community formation. But that task was impossible to accomplish without in fact becoming a committed part of the library community. It was Deet's dedication to serious science that had brought them together. Now that very dedication was stealing her away. It would hurt her more to leave the library than it would to lose Leyel.

Not true. Not true at all, he told himself sternly. Self-pity leads to self-deception. Exactly the opposite is true-- it would hurt her more to lose Leyel than to leave her community of librarians. That's why she consented to go to Terminus in the first place. But could he blame her for being glad that she didn't have to choose? Glad that she could have both?

Yet even as he beat down the worst of the thoughts arising from his disappointment, he couldn't keep some of the nastiness from coming out in his conversation. "How will you know when your experiment is over?"

She frowned. "It'll never be over, Leyel. They're all really librarians-- I don't pick them up by the tails like mice and put them back in their cages when the experiment's done. At some point I'll simply stop, that's all, and write my book."

"Will you?"

"Write the book? I've written books before, I think I can do it again."

"I meant, will you stop?"

"When, now? Is this some test of my love for you, Leyel? Are you jealous of my friendships with Rinjy and Animet and Fin and Urik?"

No! Don't accuse me of such childish, selfish feelings!

But before he could snap back his denial, he knew that his denial would be false.

"Sometimes I am, yes, Deet. Sometimes I think you're happier with them."

And because he had spoken honestly, what could have become a bitter quarrel remained a conversation. "But I am, Leyel, " she answered, just as frankly. "It's because when I'm with them, I'm creating something new, I'm creating something with them. It's exciting, invigorating. I'm discovering new things every day, in every word they say, every smile, every tear someone sheds, every sign that being one of us is the most important thing in their lives."
