Miles groaned. "If you start allowing personal motivations, as well as political ones—it could have been in return for anything ImpSec has done to anyone any time in the last thirty years. It doesn't even have to be sane—someone could have been nursing a grudge all out of proportion to the original injury. That is not the end of the problem to start with, it's too damned vast. I'd prefer to start with the chip. There's only one of it." He cleared his throat. "There's still the problem of not getting stunned at the door. I hadn't intended to take on ImpSec single-handed. I'd assumed I'd have a real Auditor to hide behind, one of those portly retired admirals, say—and I still think I would like to have a witness. An assistant, to be sure, but really, a witness. Someone I can trust, and you can trust, someone with the requisite amount of security clearance but who is not himself in ImpSec's hierarchy."

"Do you have someone in mind?" asked Gregor.

"My God," said Ivan, unconsciously echoing Gregor, as he gaped at Miles. "Is that real?" His finger reached out to tick the heavy gold chain of the Imperial Auditor's rank and office now hanging around Miles's neck. Its thick links connected big square enameled plaques chased with the Vorbarra arms and logos. It ran over Miles's shoulders and dipped across his chest, and weighed about a kilo, Miles judged. The electronic seal appended from the center in a gold clasp, also engraved with Gregor's arms.

"You want to try to peel off the foil wrapping and eat the chocolate inside?" Miles inquired dryly.

"Urgh." Ivan looked around Gregor's office. The Emperor sat on the edge of his comconsole desk, one leg swinging. "When Gregor's liveried man came galloping into HQ and yanked me off work, I thought the damned Residence was burning down, or my mother'd had a heart attack, or something. But it was only you, coz?"

"That's Lord Auditor Coz to you, for the duration."

Ivan appealed to Gregor. "Tell me this is a joke."

"No," said Gregor. "Quite real. An audit is exactly what I want. I, or to put it more officially, We are not happy with current progress. As you know, an Imperial Auditor may request anything he pleases. The first thing he requested was an assistant. Congratulations."

Ivan rolled his eyes. "He wanted a donkey to carry his luggage, and the first ass he thought of was me. So flattering. Thanks, Lord Auditor Coz. I'm sure this is going to be just a joy."

Miles said quietly, "Ivan, we're going in to audit ImpSec's handling of Illyan's breakdown. I don't know what kind of load I'll be asking you to carry, but there's at least a chance it'll be high explosives. I need a donkey I can rely on absolutely."
