I stare at the A-gate, speculating. There's a very good chance that it's not infected with Curious Yellow, because they wouldn't want to risk infecting themselves. But it still won't help me escape, and it probably won't work for me anyway unless I can hold a metaphorical gun to Fiore's head, threaten him with something even more frightening than the prospect of Yourdon's revenge—and if I've got the measure of Yourdon, any revenge he'd bother to carry out would truly be a worse fate than death.

Shit. I need to think about this some more. But at least I've got until tomorrow, when Fiore returns.

BUSINESS is dead, literally dead. After I go back up top and lock the repository, I flip the door sign to OPEN and sit at the front desk for a couple of hours, waiting tensely to see if the zombies are going to come and drag me off to prison. But nothing happens. I haven't tripped any alarms by my choice of lunchtime reading matter. With hindsight it's not too surprising. If there's one place Fiore and Yourdon and the mysterious Hanta won't want under surveillance, it's wherever they're hiding their experimental tools. Their kind doesn't thrive in the scrutiny of the panopticon. Which, as it happens, gives me an idea.

Midway through the afternoon I lock up for half an hour and hit the nearest electronics shop for a useful gadget. Then I spend a nervous hour installing it in the cellar. Afterward, I feel smug. If it works, it'll serve Fiore and Yourdon right for being overconfident—and for making this crazy simulation too realistic.

Business is so dead that I go home half an hour early. It's a warm summer evening, and I've got about two kilometers to walk. I barely see anyone. There are some park attendants out mowing the grass, but no ordinary folks. Did I miss a holiday or something? I don't know. I put one foot in front of the other until I hit the road out of the town center, follow it down into a short stretch of tunnel, then back into daylight and a quiet residential street with trees and a lazy, almost stagnant creek off to one side.

I hear voices and catch a faint smell of cooking food from one of the houses as I walk past. People are home—I haven't mysteriously been abandoned all on my own. What a shame. I briefly fantasize that the academicians of the Scholastium have figured out that all is not well in YFH-Polity and arrived to evacuate all of us inmates while I waited behind the library counter. It's a nice daydream.

Pretty soon I come to the next road tunnel linking hab segments. This time I pull out a flashlight as I pass out of sight of the entrance. Yes, just as I guessed—there's a recessed doorlike panel in one wall of the tunnel. I pull out a notepad and add it to my list. I'm slowly building up a map of the interrelated segments. It looks like a cyclic directed graph, and that's exactly what it is, a network of nodes connected by linesrepresenting roads with T-gates along their length. Now I'm adding in the maintenance hatches.

You can't actually see a T-gate—it's just that one moment you're in one sector and the next moment you've walked through an invisible brane and you're in another sector—but the positioning of the hatches can probably tell me something if I'm just smart enough to figure it out. Ditto the order of the network: if it's left-handed or right-handed, or if there's a Hamiltonian path through it. In the degenerate case, there may be no T-gates at all; this might actually be a single hab cylinder, divided up by bulkheads that can be sealed against loss of pressure. Or all the sectors may be in different places, parsecs apart. I'm trying to avoid making assumptions. If you don't search with open eyes, you risk missing things.

I get home at about my usual time, tense and nervous but also curiously relieved. What's done is done. Tomorrow Fiore will either notice my meddling, or he won't. (Or with any luck he'll assume Yourdon did it, which I think is equally likely. There's no love lost between those two, and if I play my cards right, I can exploit their division.) Either way I should learn something. If I don't . . . well, I know too much to stop now. If they knew how much I've figured out about their little game, they'd kill me immediately. No messing, no ritual humiliation in front of the score whores in Church, just a rapid brainsuck and termination. Fiore's playing with fire.

Sam is in the living room, watching TV. I tiptoe past him and head upstairs, badly in need of a shower. When I get to my room I shed my clothes, then go back to the bathroom and turn the water on, meaning to wash today's stresses away.

Seconds after I get in I hear footsteps, then the bathroom door opening. "Reeve?"

"Yeah, it's me," I call.

"Need to talk. Urgently."

"After I finish," I say, nettled. "Can't it wait?"

"I suppose."

Small torments add up; I'm now in a thoroughly bad mood. What's life coming to, when I can't even take a shower without interruption? I soap myself down methodically then wash my hair, taking care to rub the inefficient surfactant gel into my scalp. After a couple of minutes of rinsing, I turn off the water and open the door to reach for my towel, to be confronted by a surprised-looking Sam.

"Pass me the bath sheet," I tell him, trying to make the best of things. He complies hastily. Months of living in this goldfish bowl society have done strange things to my body-sense, and I feel surprisingly awkward about being naked in front of him. I think he feels it, too. "What's so important?" I step out of the shower as he holds the towel for me.

"Phone call," he mumbles, trying to look away—his eyes keep drifting back toward me.

"Uh-huh. Who from?" He folds me in the towel as if I'm a delicate treasure he's trying not to touch. I shiver and try to ignore it.

"From Fer. He and El, they've heard something bad from Mick, and they're talking about sorting it out."

"Bad." I try to concentrate. The water on my skin is suddenly cold. "What kind of bad?"

"It's Cass, I think." I tense up inside. "Mick gave them some crazy story about hearing from Fiore. Said the Priest told him that one of the rules in here is, what was it, ‘be fruitful and exponentiate.' That you can get a gigantic score bonus for having children."

"That's not good," I say carefully, "but it might just be Mick acting in character."

"Well, yes, that's what Fer said, but then Mick told El he was going to get that bonus whether or not Cass wanted it." He sounds apprehensive. "El wasn't sure what that meant."

My mind races. "Cass wasn't at Church yesterday, Sam. Last time I saw her she wouldn't talk—she seemed afraid." I have a nasty feeling that I know what's going on. I really don't want it to be true.

"Yes, well, Fer called me when El told him Mick had made some kind of joke about stopping Cass trying to escape for good. He wasn't sure just what it was but said it didn't sound right. Reeve, what's going on? What are we going to do if it turns out he's been tying Cass up while he's been at work, or using physical force, or something?"

For someone living in a dark ages sim, Sam can be heartbreakingly naive at times. "Sam, do you know what the word ‘rape' means?"

"I've heard it," he says guardedly. "I thought it had to involve strangers, and usually killing. Do you think—"

I turn round. "We've got to find out what's going on, and we've got to get her out of there if it's true. I don't think we can count on the police zombies, or Fiore for that matter, to help. Fiore's messed up in the head anyway, even Yourdon thinks so." I pause. "This is very bad."

The thought of what Cass might be going through horrifies me, especially as I can guess how some of our cohort will react if we try to rescue her. Before last Sunday I might have been more hopeful, but now I know better than to expect anything but gruesome savagery from our neighbors if they think their precious points are at risk. "I think Janis would help, but she's ill. Alice, maybe. Angel is scared but will probably follow if we approach her right. Jen—I don't want Jen around. What about you guys?"
