I nod vigorously. "I, I'll be at the front desk if you need me." My teeth are nearly chattering. What is it with this guy? I've met misanthropes before, but Yourdon is something special.

Fiore and the Bishop hang out in the archive, doing whatever it is they do in there for almost three hours. At a couple of points I hear raised voices, Fiore's unctuous pleading followed by the Bishop hissing back at him like an angry snake. I sit behind the desk, forcing myself not to look over my shoulder every ten seconds, and try to read a book about the history of witch-hunts in preindustrial Europa and Merka. It contains disturbing echoes of what's going on here, communities fractured into mutually mistrustful factions that compete to denounce one another to greedy spiritual authorities drunk on temporal power. However, I find it hard to concentrate while the snake and the toad in the back room are making noises like they're trying to sting each other to death.

It's well into my normal lunch hour when Fiore and Yourdon surface. Fiore looks subdued and resentful. Yourdon appears to be in a better mood, but if this is his good humor, I'd hate to see him when he's angry. When he smiles he looks like a skull someone's stretched a sheet of skin over, colorless lips peeling back from yellowing teeth in a grin completely bereft of amusement. "You'd better get back to work then," he calls to Fiore as he strides past my desk without so much as a nod in my direction. "You've got a lot of lost headway to make up." Then he barges out through the front door as the long black limousine cruises round the edge of the block, ready to convey its master back to his usual haunts.

A few minutes later Fiore bumbles past me with a sullen glare. "I'll be round tomorrow," he mutters, then stomps out the door. No limousinefor the Priest, who staggers off on foot in the noonday heat. My, how the mighty are fallen!

I watch him until he's out of sight, then walk over and flip the sign on the door to CLOSED. Then I lock up and take a deep breath. I wasn't expecting this to happen today, but it's too good an opportunity to miss. I go fetch my bag from the staff room, then head for the repository.

It's time for the moment of truth. Less than a hundred seconds after Fiore left the building, I slide the laboriously copied key into the lock. My heart is pounding as I turn it. For a moment it refuses to budge, but I jiggle it—the teeth aren't quite engaging with the pins—and something falls into position and it squeals slightly and gives way. I push the door wide, then reach for the light switch.

I'm in a small room with no windows, no chairs, no tables, one bare electric bulb dangling on a wire from the ceiling, bookshelves on three walls, and a trapdoor in the middle of the floor.

"What is this shit?" I ask aloud, looking round.

There are box files on all the shelves, masses of box files. But there are no titles on the spines of the boxes, just serial numbers. Everything's dusty except the trapdoor, which has been opened recently. I inhale, then nearly go cross-eyed trying not to sneeze. If this is Fiore's idea of housekeeping, it's no wonder Yourdon was pissed at him.

I look at the nearest shelf and pull down one of the files at random. There's a button catch and I open it to find it's full of paper, yellowing sheets of the stuff, machine-smooth, columns of hexadecimal numbers printed in rows of dumb ink. There's a sequence number at the top of each sheet, and it takes me a few seconds to figure out what I'm looking at. It's a serialized mind map, what the ancients would have called a "hex dump." Pages and pages of it. The box file probably holds about five hundred sheets. If all the others I see contain more of this stuff, then I'm probably looking at about a hundred thousand sheets, each containing maybe ten thousand characters. Whatever is stored in this incredibly inefficient serial medium, it isn't very big—about the same size as a small mammal's genome, maybe, once you squeeze out all the redundant exons. It's three or four orders of magnitude too small to be a map of a human being.

I shake my head and put the box file back. From the level of dust on top of it, it hasn't been touched for quite a time. I don't know what this stuff is, but it isn't what Fiore and Yourdon came here to look at. Which leaves the trapdoor.

I bend down and grab the brass ring, then lift. The wooden slab hinges up at the back, and I see a flight of steps leading down. They're carpeted, and there are wooden handrails to either side. Okay, so there's a secret basement under the library, I tell myself, trying not to giggle with fear. What have I been working on top of?

Of course I go downstairs. After what Fiore did to Phil and Esther, I'm probably dead if they find me in the repository. Taking the next step is a logical progression, nothing more.

The steps go down into twilight, but they don't go down very far. The floor is three meters below the trapdoor, and there's a light switch on the rail at the bottom. I flick it and glance around.

Guess what? I'm not in the dark ages anymore.

If I was still in the dark ages, this would be a musty basement with brick walls and wooden lath ceiling, or maybe poured concrete and steel beams. They weren't big on structural diamond back then, and their floors didn't grow zebrastripe fur, and they used short-lived electrical bulbs instead of surfacing their ceilings with fluorescent paint. There's a very retro-looking lounger in a mode that I'm sure went out of fashion some time between the end of the Oort colonial era and the first of the conservationista republics, and some weird black-resin chairs that look like the skeletons of insects, if insects grew four meters tall and supported themselves with endoskeletons. Hmm. I glance over my shoulder. Yes, if Yourdon and Fiore were having a knockdown shouting match in here with the hatch open, I might just about have heard it at the front desk.

The other items in the basement are a lot more disconcerting.

For starters, there's something that I am almost certain is a full military A-gate. It's a stubby cylinder about two meters high and two meters in diameter, its shell slick with the white opacity of carbonitrile armor. There's a ruggedized control workstation next to it, perched on a rough wooden plinth—you use those things in the field when you'reoperating under emission control, to make field expedient whatever it is you need in order to save your ass. Got plutonium? Got nuke. Not that I've got the authentication ackles to switch the thing on—if I mess with it I'll probably set off about a billion alarms—but its presence here is as incongruous as a biplane in the bronze age.

For seconds, the walls are lined with racks of shelving bearing various pieces of equipment. There's what I'm fairly certain is a generator pack for a Vorpal sword, like the one on the Church altar. That brings back unpleasant memories, because I remember those swords and what you can do with them—blood fountaining out into a room where the headless corpses are already stacked like cordwood beside the evacuation gate—and it makes me feel nauseous. I take a quick breath, then I look at the shelves on the other side of the room. There are lots of them, some of them stacked with the quaint rectangular bricks of high-density storage, but most of the space is given over to ring binders full of paper. This time, instead of serial numbers on the spines, there are old-fashioned human-readable titles, although they don't mean much to me. Like Revised Zimbardo Study Protocol 4.0 , and Church Scale Moral Delta Coefficients , and Extended Host Selection Criteria —

Host selection criteria? I pull that one off the shelf and begin reading. An indeterminate time later I shake myself and put it back. I feel dirty, somehow contaminated. I really wish I didn't understand what it said, but I'm afraid I do, and now I'm going to have to figure out what to do with the knowledge.
