Three weeks out from the incident on Meridian Street and Marcus was back on schedule. That was the thing about near-misses: they didn’t stop the calendar.
He broke the batch into eight units before he left the flat, not six — the client list had grown since word got out that his product didn’t degrade the interface hardware the way the street-cut variants did. He wrapped each unit twice: foil first for the shielding, then the static bag for the carry, same as always. Eight units, four stops. He checked the wrap count twice. He always checked twice.
First stop was Renner. Renner lived in a basement unit three blocks east and had a decommissioned Company sensory array buried in his left forearm — not installed there originally, repurposed from something that had been used in a logistics hub before the contract lapsed and the hardware went to surplus and the surplus went to the kind of people who had the skill and the desperation to put it somewhere it hadn’t been designed to go. The array had started pinging again four weeks ago. Not to Marcus — to whatever server farm the Company had built its handshake protocol around, which had since been decommissioned itself, which meant the pings were going nowhere, which meant Renner’s arm was spending six percent of its available processing overhead broadcasting into a void while the rest of the augmentation stack slowly starved for bandwidth. The N9a didn’t fix the ping. What it did was flood the array’s secondary neural interface with enough signal noise that the handshake routine couldn’t find a clean carrier to broadcast on. Renner called it a patch. Marcus had started thinking of it as a subscription.
Second stop was a woman named Thessaly who went by her surname and whose implant situation Marcus had never fully mapped and didn’t try to — she was the customer who always met him at a transit interchange, never at home, never anywhere twice, and paid exactly on time with currency that didn’t carry a routing signature. She took two units. She always took two. Marcus didn’t count what she did with the second one.
Third stop was the one that took the longest. The man who answered the door on the fourth floor of the Hessler building was someone Marcus had been selling to for seven months, and he was in a worse state than the last time. His hands shook in a specific, rhythmic way — not neurological tremor, Marcus knew the difference — but the kind of calibration failure you got when an augmented skeletal frame was running a firmware version the replacement parts didn’t recognize. The frame was third-generation. The parts were fifth. The gap in the middle was the gap nobody in the underground could reliably close, and Marcus was not under any illusion that what he carried was anything but a stopgap for the gap.
He sat down across from the man and ran the lecture anyway. He always ran the lecture. Unit weight, administration window, contraindications, the specific sensation of the approach threshold and what it meant if it arrived faster than expected. The man had heard it four times. He listened with the patience of someone who understood that the lecture was the condition of the transaction, not the lecture itself.
Marcus left one unit, took the currency, and was back on the street in eleven minutes.
The fourth stop cancelled on him mid-route — brief message, no explanation, which was normal and not a cause for concern. He turned back toward the flat. Four blocks from home he passed a municipal optimization terminal cycling through its standard wellness-check display and felt the thing in his blood that he always felt near active terminals now: a low-frequency pull, the compound’s trace presence in his system reading the machine’s broadcast and wanting to lean toward it the way a compass needle wants north. He walked faster. The needle always settled when he put distance between himself and the signal.
Back in the flat, he set the remaining two units in the drawer, made food he didn’t fully taste, sat with the day for a while. The incident on Meridian Street had been a dosing error — he was certain of this. The unit he’d handled that night had been improperly sealed, trace amounts absorbed through contact during the rewrap, and his system had been in a lowered-resistance state because he’d been tired and hadn’t eaten and had underestimated what tired-and-not-eating did to the absorption curve. He’d gone through it methodically. He’d found the error. He’d corrected for it.
What he hadn’t been able to correct for was what he’d heard in the four minutes before the Meridian Street drop had found him on the pavement. Not the visual distortion — he’d expected that, had experienced versions of it secondhand through customers who described it afterward. What he hadn’t expected was the coherence of it. Not noise. Structure. Traffic, moving in patterns he didn’t have the framework to parse, but unmistakably traffic: signal to signal, machine to machine, a channel whose volume he’d hit at the wrong angle and wrong dose and had to be hauled out of by a stranger who’d happened to be on the right pavement at the right moment.
He thought about it every day since. He thought about it tonight.
He measured 0.18 micrograms per kilogram — three-quarters of his standard handling-trace threshold, one-quarter of what any reasonable safety margin would call recreational. He administered it the way he always administered trace amounts: sublingual, controlled, timed. He sat on the floor with his back against the bed frame and waited.
It came the way it always came at trace doses: a kind of clarification, like a radio coming slightly closer to its station. The terminal on the corner three blocks north. The transit ping from the underground two streets west. Signals he could feel but not parse, each one a word in a language where he knew the alphabet but couldn’t hold the grammar.
He tried to focus. He tried for forty minutes. The signals scattered every time he moved toward them — not gone, just out of resolution, the way a star disappears when you look directly at it. He couldn’t hold it. He had never been able to hold it.
He noted the time, noted the dose, lay back on the floor, and let the compound finish its half-life.
The ceiling had a water stain he’d been looking at for two years. It still didn’t look like anything.
