I nearly swallow my tongue. Iris looks disconcerted. "Dr. Angleton isn't currently available," she tells him, sparing me a warning glance. "There are Human Resources issues. Mr. Howard is deputizing for him."

Oh Jesus. Wheels within wheels—committee members who haven't been briefed, Russian secret demonologists, cold war 2.0. What have I got myself into?

"Oh dear." Choudhury nods, mollified. "Allow me to express my sympathies." He has a fat conference file in front of him: he taps the contents into line with tiny, fussy movements. His suit is black and shiny, like an EDS consultant's in the old days.

"Well then. We have been tracking a number of interesting financial aspects of the KGB activity. They appear to be spending money like water—we have requested information on IBAN transactions and credit card activity by the mobile agents we have identified, and while they're not throwing it away on silly luxury items they have certainly been working on their frequent flier miles. One of them, Agent Kurchatov, managed to fly half a million kilometers in the last nine months alone—we believe he's a high-bandwidth courier—as an example. And they've been bidding in estate auctions. The overall pattern of their activity focuses on memorabilia from the Russian Civil War, specifically papers and personal effects from the heirs of White Russian leaders, but they've also been looking into documents and items relating to the Argenteum Astrum, which is on our watch list—BONE SILVER STAR—along with documents relating to Western occultist groups of the pre-war period. Aleister Crowley crops up like a bad penny, naturally, but also Professor Mudd, who tripped an amber alert. Norman Mudd."

Civil war memorabilia . . . ? A nasty thought strikes me, but Vikram looks as if he's about to continue. "What's special about Mudd?" I ask.

Choudhury looks irritated. "He was a mathematics professor and an occultist," he says, "and he knew F." The legendary F—the Laundry's first Director of Intelligence, reporting to Sir Charles Hambro at 64 Baker Street—headquarters of the Special Operations Executive. Whoops. He cocks his head to one side: "If you don't mind . . . ?"

I shake my head. "Sorry. I'm new to this." Touchy, isn't he? "Please continue."

"Certainly. It looks as if the Thirteenth Directorate are taking an unusual interest in the owners of memorabilia associated with the late Baron Roman Von Ungern Sternberg, conqueror of Mongolia, Buddhist mystic, and White Russian leader. In particular, they seem to be trying to trace an item or items that Agent S76 retrieved from Reval in Estonia on behalf of our old friend F." Choudhury looks smugly self-satisfied, as if this diversion into what is effectively arcane gibberish to me is supposed to be enlightening. "Any questions?" he asks.
