Known Frequency

The 6:47 ran late.

Miles knew this because he'd checked the app four times since locking his apartment door, each refresh a small act of bargaining with himself. The transit authority's real-time system was essentially decorative — he'd patched into their backend once out of boredom and found the delay algorithm operated more on optimism than data. Knowing that didn't help. He checked again anyway.

He'd put the errands off for three days. Pharmacy. Shipping depot. Hardware store on Clement for a specific gauge of wire that online retailers consistently, infuriatingly got wrong. A reasonable list. Manageable. The kind of thing that should not require this much negotiation with his own nervous system just to begin.

He was already tired and he hadn't done anything yet.

The platform was loud in the particular way underground spaces were loud — sound with nowhere to go, bouncing off tile and concrete until it was less noise and more pressure. Miles positioned himself at the far end away from the cluster of after-work bodies that had taken over the center, back against the wall, sight lines clear in both directions.

His headphones were on but not playing anything.

People never understood that part. Sometimes it wasn't about blocking sound. Sometimes it was just about having something between his skull and the open air. A boundary. Even a symbolic one.

The 6:47 arrived at 7:04.

He told himself it was fine. Got on anyway. Third car from the front, seat nearest the door. Exit options. He didn't examine that instinct anymore, it was just architecture — the way he was built.

Then he saw the light.

One panel overhead, flickering in that irregular rhythm that his brain locked onto immediately and refused to release. Not fast enough to be a strobe. Not steady enough to become background. Just present. Just wrong. A small malfunction pulsing at a frequency that his nervous system treated like a question it couldn't stop trying to answer.

He moved his eyes to his phone. Looked away. Looked back without meaning to.

Still flickering.

The car filled at the next stop and the next and by the third his personal space had compressed to something theoretical. A woman's stroller bumped his ankle once, twice, a third time she didn't notice and he noticed all three. Two men diagonal from him were having a conversation calibrated for a parking lot. Somewhere behind him a child was making a sound — not crying, just a sustained high note of displeasure — that cut through everything else and lodged itself at the base of his skull.

Someone's earbuds were leaking bass. Just the ghost of it. A thin metallic thread his brain kept reaching for and failing to resolve into actual music.

The light kept flickering.

Miles breathed through his nose and stared at his list on his phone screen. Pharmacy. Depot. Hardware store. He read the words without absorbing them. His leg had started bouncing without his permission, heel tapping the floor in a rhythm his body had chosen independently, and he pressed his foot flat and it started again almost immediately.

You're fine, he told himself. This is a train. You are on a train. People do this.

A stranger grabbed the overhead rail directly above him — an arm appearing suddenly in his peripheral vision — and his shoulders jerked up hard before he could stop them. The man didn't notice. Nobody noticed. Miles sat very still and breathed and felt the particular exhaustion of performing stillness while everything inside him was running.

It stopped between stations at 7:22.

The intercom crackled once, offered something that had been words at some point in its life, and went silent. Around him the car exhaled collectively — the resigned sigh of people who had been failed by infrastructure before and had made their peace with it. Phones came out. Someone started a podcast. The woman with the stroller gave her child a snack.

Miles pulled up the transit backend.

Signal failure two stops ahead. Estimated resolution fifteen minutes, which his experience translated to thirty, maybe forty, and the walls of the car were the same distance apart they'd always been but his body had stopped believing that.

He needed to get off.

He couldn't get off.

The car sat motionless and the flickering light asked its unanswerable question over and over and the bass from the earbuds had found a frequency that resonated somewhere behind his eyes and the child had finished its snack and resumed its sustained single note and Miles sat with his hands pressed flat against his thighs and counted his breaths and lost count and started again.

Eleven minutes.

He knew it was eleven because he watched every one of them pass.

When the train finally moved he was standing at the doors before it reached the platform. The second they opened he was through them and up the stairs and then —

The street.

It hit him the way walls hit people — all at once and with no warning. He'd been underground long enough that he'd forgotten the world had kept going without him and up here it was full evening now, that low coastal light that turned everything amber and copper, and it would have been beautiful except he had no room for beautiful right now.

The waterfront district was alive. Fully, aggressively alive. Foot traffic moving in every direction without logic, bodies threading past each other at the pace of people with somewhere to be. A restaurant nearby was exhaling heat and fryer oil in waves. A car at the corner was idling, music coming through its chassis at a frequency Miles felt in his back teeth. Someone was jackhammering half a block away — he heard it before he could locate it and for one disorienting second it seemed to come from everywhere.

He stood on the sidewalk and people moved around him like water around something stuck.

Move, he told himself. You have a list. Move.

He made it half a block.

The jackhammer stopped and was replaced immediately by a delivery truck reversing, that sustained mechanical beeping drilling into the space the jackhammer had just vacated, and Miles stopped walking and stood against a building and pressed the back of his head against the brick and closed his eyes.

He opened his eyes.

The truck kept beeping.

Miles pressed his back harder into the brick and pulled out his phone — not for anything, just to have something in his hands, something with edges and weight that belonged to him. He pulled up a waveform app he used sometimes, a visual equalizer that turned sound into something he could look at instead of just absorb. It didn't stop the noise. It just gave his brain somewhere to file it.

The jackhammer started again.

He stared at the waveform spiking on his screen and tried to breathe on the downbeats and it wasn't working, the pattern kept breaking, too many competing sources for his brain to separate and organize and he could feel himself losing the thread of functional —

Then a motorcycle revved.

Not the ambient wash of traffic. Something deliberate. Close. A specific mechanical voice cutting clean through everything else, and Miles' brain latched onto it before he could stop it — the way it always latched onto the one frequency that was different from the rest.

His eyes tracked it without permission.

Down the block. A bike pulling around the side of a building he recognized. Not from walking past it. From floor plans. Camera feeds. Access logs. The unremarkable door between the auto shop and the warehouse that was designed not to want to be looked at.

He knew that door.

He knew the code. Four digits. Changed twice in the last year to something the VP thought was clever and wasn't.

Miles looked back at the street. At the truck still beeping, the restaurant still breathing heat, the city still running at full volume completely indifferent to what it was doing to him.

He looked at the door.

His body made the decision before his brain finished the argument. One foot in front of the other, hood up, head down. The panel was exactly where the schematics said it would be. He punched in the code without slowing down.

The lock disengaged.

He pushed through and let the door fall shut behind him and stood in the relative dark on the other side and just breathed.

The air inside was different.

Not quiet exactly — he could hear voices somewhere deeper in the building, the muffled bass of music, the clank of something mechanical — but the immediate assault of outside was gone and his nervous system registered the difference before his brain did. His shoulders dropped half an inch. His jaw unclenched. He hadn't known it was clenched.

He stood just inside the door with his eyes closed and let himself have it. Just for a moment. Just long enough to stop being in survival mode and start being a person again.

His hands were the first thing he let go of — fingers spreading wide at his sides, that deliberate release his occupational therapist had taught him when he was sixteen and that he'd never admitted to anyone still worked. Then his breathing, finding the slower rhythm underneath the shallow one he'd been running on. His weight settled into his heels. The waveform app was still running on his phone and he watched it through half closed eyes, the spikes smaller now, manageable, something his brain could actually organize.

The muffled music thumped steadily through the walls.

He could work with steady.

His hood was still up and he pushed it back, rubbed a hand over his face with the particular thoroughness of someone clearing a screen. He could feel his heartbeat coming down. Could feel the edges of himself returning, the sense of where he ended and the room began, which had gotten genuinely unclear on that sidewalk.

Okay.

Okay he was —

Someone cleared their throat.

Miles went completely still.

It was a specific kind of stillness. The kind that happens before the brain has finished processing what the body already knows. The kind that precedes the stomach dropping out entirely.

He turned around slowly.

Seven men.

They were arranged across the bay with the casual geometry of people who hadn't arranged themselves at all, who had simply been here, who had been here the entire time. A couple were standing near a bike in various states of maintenance, tools still in hand. One was leaning against a workbench with his arms crossed and an expression that had moved past confusion and arrived somewhere considerably less welcoming. Another sat on a crate near the far wall and hadn't changed his posture at all, which was somehow the most unsettling response of all of them.

They were all looking at him.

The patches on their cuts registered in Miles' brain in the automatic way that information always registered — filed, catalogued, cross referenced against what he already knew. He knew these men. Not personally. But he knew their names and their histories and their positions in the hierarchy and several things about several of them that they would not enjoy knowing he knew.

That information was not currently helpful.

What was currently happening was seven men wearing expressions that ranged from pissed off to confused to something in the neighborhood of genuinely dangerous all aimed at one person who had just let himself into their space uninvited and then stood there with his eyes closed like he was at a spa.

The man with the crossed arms spoke first.

"You want to tell me how you just walked in here."

It wasn't a question.
