The hollowness of his office, issued to him merely on Gregor's whim, echoed in his head. He missed his Dendarii backup. If he'd thought for a minute this appointment was going to go real, even temporarily, he'd have started building a staff of suitable experts, raided from, though independent of, all other Barrayaran organizations. He knew a number of good fellows from ImpSec, for instance, close to their twenty-year anniversaries, who might be willing to retire and lend their training to his use. Study the other Auditors' staffs, and model his from theirs. Pin Lord Auditor Vorhovis to the nearest wall, and not let him go until he'd disgorged everything he knew about doing his job. A new apprenticeship. I'm doing it backwards again, dammit. A familiar unfamiliarity. You'd think I'd learn.

So. What should he do next, or rather, first? His one piece of physical evidence, the bioengineered prokaryote, appeared to lead back to Jackson's Whole, if he could trust Weddell's technical expertise, which he did. Should he go haring off to Jackson's Whole, to supervise the search? The thought made him shudder.

That sort of fieldwork was just the sort of thing to delegate to a team of field agents, of the kind he'd formerly been himself. Speaking of expertise. So the obvious thing to do was delegate it, except . . . if ImpSec itself was tainted with suspicion . . .

If the production of the prokaryote had been a purely commercial enterprise, there was no motivation to be found on Jackson's Whole. Well, maybe revenge. "Admiral Naismith" had seriously annoyed several Jacksonian Great Houses there on his last visit: if they'd finally figured out who he was working for . . . Yet House Fell, which could command the resources for this nasty piece of sabotage, had not been seriously discommoded by him; House Bharaputra, which had been more upset, was perhaps not crazy enough to start a private war with Barrayar—there was no obvious profit in it, after all; House Ryoval, which both had the resources and was crazy enough, was dismembered, Baron Ryoval dead.

No. The weapon might have come from Jackson's Whole, but the crime had been committed here. Intuition, boy? So what was he supposed to do, lie in wait trying to ambush his own subconscious? He'd go quietly mad.

Maybe he needed to give his intuition demon more to chew on. Stir up ImpSec? Stir up your own assassination, maybe? At least it would be entertaining, and less frustrating than this blankness.

Do you really think it's an inside job? The intuition demon, as usual, was too coy to give him a straight answer. But there was this; anyone could go scope out Jackson's Whole. Only an Imperial Auditor could get inside ImpSec HQ. Solving this puzzle was not going to be a one-man job, but it was all too apparent what his part in it must be.

ImpSec it is, then.
