"Didn't hear anything more about him one way or another, till this last Midsummer. Then Illyan asked me if I thought I could stand to work with Vorkosigan as my second in Domestic Affairs. Warned me he was hyperactive, and insubordinate as hell, but that he got results. Said I'd either love him or hate him, though some people did both. He said Vorkosigan needed a dose of my experience. I said . . . I'd try. The implication was pretty clear. I wouldn't have minded training my replacement. Being asked to train my boss was a little hard to swallow. Thirty years of experience, jumped over . . . But I swallowed it."

Gregor's attention was wholly on Haroche, and Haroche's, perforce, wholly on Gregor. It was as if Gregor generated his own little personal force-bubble, just like those used by a Cetagandan haut-lady, with only the two of them inside. Haroche grew more intense, leaning forward, his knee almost touching Gregor's.

"Then Vorkosigan . . . shot his foot off. So to speak. Good and proper. I didn't have to do him, he did himself, better than I could ever have imagined. He was out, I was in. I had my chance back, but . . . Illyan was good for another five years, maybe ten. There's more young hotshots coming up all the time. Now, while I was still at my peak, I wanted my chance. Illyan was getting stale, you could see it, feel it. Getting tired. He kept talking about retiring, but he never did anything. I wanted to serve the Imperium, serve you, Sire! I knew I could, if I got my chance. In time, in my time. And then . . . I thought of that damned Komarran powder."

"Just when did you think of it?"

"That afternoon, when Vorkosigan came stumbling out of Illyan's office with his eyes torn off. I went down to the Evidence Rooms on another matter, walked right by that shelf, as I'd done a hundred times before, but this time . . . I opened the box, and pocketed two capsules. It was no trouble walking out with them; it was the box that was screamer-tagged, not its contents. Of course I wasn't searched. I knew I'd have to do something about the monitors, eventually, but even if someone had visually checked them, all they would see was me, authorized to take anything I wanted."

"We know where. When did you administer the prokaryotes to Illyan?"

"It was . . . a few days later. Three, four days." Haroche's hand jerked in air; Miles could imagine the stream of tan smoke spinning from his fingers. "He was always popping into my office, to check out facts, to get my opinion."

"Did you use both capsules then?"
