Chapter 14: Going Dark

The chalk mark at Canter Street was fresh — I could smell the calcium dust before I saw it, which told me Drift had been there inside the hour. Two horizontal strokes, one vertical, the signal we'd established four months ago when the Bureau rolled out its new optical-scan protocol for public infrastructure and the old chalk system needed an update. It meant: come through the south service entrance, not the maintenance hatch. It meant he'd already seen me coming.

I had left my vehicle three blocks north and walked the rest, taking the long route past the recycling aggregation facility where the civic sensor grid had a dead patch the size of a city bus, courtesy of a moisture leak in the conduit housing that the Bureau's maintenance queue had been ignoring for eleven months. Drift had pointed it out to me on our third meeting, the way a man who has memorized a building's weaknesses points out a cracked window — not with urgency, just notation. This is the shape of what they can't see.

The south service entrance was a corroded door set into the underside of the transit overpass, partially concealed by the support strut and a permanent accumulation of water-shadow that the overhead lights never reached. I pressed my back against the strut and waited for the transit car to pass above before I pulled it open. The hinges were silent. Drift had oiled them himself, three weeks ago. That kind of maintenance tells you everything about a person's relationship to contingency.
