Five stories deep, towering over the Thames behind triple-paned glass and electronic countermeasures, crammed with fiber optics and copper wire, protected by gates and guards and more surveillance than even the most paranoid pedestrian could imagine, it was considered by many to be an eyesore, and far too ostentatious to house M16. Disparagingly referred to as Babylon-on-Thames, or the Ceausescu Towers, or-Paul Crocker's personal favorite-Legoland, it had an interior that was a maze of white corridors and nondescript doors with only the barest departmental labeling, part of the ever-present attempt to maintain secrecy in a Service that still winced whenever it hired anyone named Guy, Donald, or, worst of all, Kim.

It worked, and more than one fresh-faced officer, new to the Firm, had found himself lost in the halls and in dire need of direction.

The nicest office, situated just below the top floor, belonged to the Chief of Service, currently Sir Francis Barclay or, in keeping with the tradition established by Mansfield Cumming in 1922, C. From the hall, it looked as nondescript as any other in the building. Inside the outer office, it had desks for not one but three personal assistants. But once one went through and into the inner office, everything changed, as if all pretension to modernity had been rejected in favor of those good old days when spying was deemed a Gentlemen's Game. Thick Oriental carpet and a mahogany desk that could keep eight afloat should the Thames burst its banks, three modestly comfortable leather-backed chairs arrayed to face it, and its larger brother positioned behind, to make certain everyone seated knew their place in the room. A separate sitting area off to the side with two couches, two armchairs, and a coffee table. A sidebar heavy with crystal glasses and decanters, and the mandatory door leading to the private washroom, which, rumor held, contained not only the toilet but also a shower and a whirlpool bath.
