Chapter 19: Line of Contact

The alert tone was two notes—low, then lower. Not the kind of sound that made you jump. The kind that made your nervous system understand without asking. The biometric response was immediate: my heart rate shifted, my breathing changed, the neural core accelerated its processing. The alert was working exactly as designed. It was a signal that the hunting had begun.

"SILKSCREEN," Ryker said. His hands didn't leave the keyboard. He was still running the feed, still tracking. His voice carried the particular quality of someone who'd already moved past panic into operational mode. The panic would come later, if they survived. Right now there was only the immediate calculation of what the data meant and how fast it was moving toward us.

I watched the counter-surveillance map on his center monitor. Three blue dots forming a perimeter eight blocks north. Moving south on a pattern that looked random until you understood what random meant: scanning. The sweep was methodical. Disciplined. This wasn't panic response. This was a planned operation. They were looking for something specific, which probably meant they knew something specific. They were looking for active neural signatures, the heat signatures that only showed up when someone had their tap jacked in and running. The heat bloom of an active neural core was impossible to hide from the right sensors.

Mine was off. Dark. No light in the port on my wrist. I'd shut it down two hours ago, after I'd finished the initial decryption mapping. But they'd widen the net. They always did. And an active tap in this sector meant something had spooked them. Which meant they were looking for the right kind of person. Which might mean they were looking for me, or it might mean they were looking for Ryker, or it might mean they were looking for anyone with the kind of neural infrastructure that could be a threat.

The blue dots moved. One block north became two blocks north. The algorithm was accelerating. They were getting closer, and the algorithm was adapting to whatever feedback it was receiving. "How long?" I was already closing the decryption logs. The files on my drive went dark. The monitor screen cleared. Everything we'd been doing was being erased from visibility, leaving no heat signature, no evidence, nothing for their sensors to grab onto.

"Two blocks before they have direct line of sight on this building."

A statement of fact: we move now or we don't move. The moment was collapsing. The options were closing. The calculation had been run and the result was clear: stay and get caught, or run.

Ryker was already standing. He'd moved in the way that meant he'd already calculated the route before he spoke. Down the service stairs. Two levels. There was a maintenance sub-level that connected to the storm runoff, if you were willing to get wet. If you were willing to go low enough that the buildings' roof-level sensors couldn't reach you. If you were willing to go deep enough into the city's arterial systems that the SILKSCREEN units would have to make a choice: follow you down and lose high-ground advantage, or keep scanning from the surface.

"Go," he said.

I'd learned that his "go" meant move in whatever direction I was about to move anyway, but faster. No argument in it, no room in it, just the coordinate of a thing that was already happening. I grabbed the data drive—the only thing that mattered, the only thing we couldn't leave behind. The decryption file. The memory that wasn't mine. I shoved it into my jacket pocket. Left everything else. The bench we'd been sitting at would tell them someone had been here, but not who or for how long. The monitors would be dark by the time they arrived. The keyboards would be cold. They'd find the space we'd occupied, but not the signature of it. Not unless they had thermal imaging sensitive enough to read residual heat from abandoned workstations.

The stairs were concrete and echoed. Three flights down and the air changed—colder, wet, carrying the smell of earth and static that meant the storm drains were close. The temperature dropped with each step down. The humidity increased. My breath was visible in front of my face, small clouds of white that dissipated into the cold. The sub-level access was behind a panel that had been rusted open for maybe five years. No locks left to pick. Just the dark and the drop. The opening yawned downward. I could hear water somewhere deeper. The sound of flow. The city's internal irrigation system, constantly moving water away from the places where humans lived, down into the depths.

"Left," Ryker said behind me. I couldn't see him in the darkness, but I could hear him. Close. The kind of close that meant he was right there if the ground disappeared or the walls got smart. His footsteps followed mine. Steady. Measured. We moved at a walk—fast but deliberate. Running in the dark underground was how you ended up in storm runoff. Down into the passages the city had forgotten.

The passage narrowed. The echo changed. We were below street level now, in the arterial system that carried the city's water away from the places people lived. This was the infrastructure of infrastructure. The pipes and tunnels that nobody thought about because they all worked in the dark. Rain came in from somewhere above—enough to make the ground slick but not enough to flood. Yet. The storm surge was still north, still moving in that careful pattern that looked like hunting. The data I'd pulled from the alerts suggested the SILKSCREEN sweep was progressing on a pattern that would bring them to the street level above us in maybe four minutes. Four minutes to find the building. Four minutes to realize we'd descended. Four minutes to make the choice: follow us down or try to cut us off at the other end.

There. The alcove. Maybe two meters across, less than that deep. A place where the city's old infrastructure had been abandoned and built around. Some vestigial part of a system that had become obsolete. Ryker pulled me deeper into it, his hand on my shoulder, and I registered the pressure of it before I registered anything else. Precise—placement, not contact. The kind of touch that communicated direction without demanding anything else.
