Chapter 2: Thirty Days

Marcus was at his desk when the first client arrived on Thursday evening.

He knew it was a client because he'd started paying attention to the sounds from 4B, which was becoming more difficult to justify as abstract curiosity. The knock came at 6:47 pm—he knew because he'd glanced at the timestamp, not because he was watching the time. The woman's voice through the wall was thin, strained. Even muffled by plaster and brick, he could hear the edge in it.

The door to 4B opened. A low greeting. A voice that didn't match its owner's state of mind—calm the way a coach's voice is calm, present without being intrusive.

Marcus had the Mahler recording playing on his speakers. He turned it off.

The session lasted fifty-two minutes. He knew this not because he was counting (he was definitely counting), but because he happened to glance at his screen when the murmur of conversation stopped at 7:39 pm. The knock on 4B's door came exactly forty seconds later—the threshold adjustment, maybe, or a moment to compose. He heard the door open. "Thank you," the woman said, and this time he could hear it in her voice: the pitch lower, the rush gone. Not dramatic. Just steadier.

He opened the spreadsheet.

He had one entry already. Now he added a second:

Client Session 1 Duration: 52 min Client arrives: anxious/strained vocalization Client departs: vocalization significantly altered (calmer, lower pitch, less rushed speech pattern) Observable effect: behavior change post-session Quality of effect: measurable but subtle

He stared at the entry for a long time before closing the laptop.

Friday brought the second client.

This one arrived in a spiral. Marcus heard the buzzer at 2:15 pm, heard the heavy footsteps on the stairs—someone who wasn't thinking about their steps. The knock was sharp. Impatient.

He moved to the hallway, ostensibly to check the mail. There wasn't any mail. He stood there anyway, in the gray afternoon light that filtered down from the skylight, and listened to 4B's door open. The woman who stepped inside was bundled into a winter coat despite it being February-mild, all coiled tension and something that looked like barely contained fury.

Marcus counted the minutes.

At 3:08 pm, the door to 4B opened again. The woman who emerged was different. Not transformed—that was the thing that fascinated him. Not transcendent or glowing or any of the theatrical things people meant when they said someone looked "healed." She just looked like someone who had taken off a heavy jacket. Her shoulders sat different. Her breathing had slowed. She pulled her own coat closed with deliberate care instead of yanking it.

She passed him in the stairwell without seeing him. He was halfway to the mail table that didn't have any mail.

Back at his desk, he added:

Client Session 2 Duration: 53 min Client arrives: high physical tension, rapid speech patterns, visible agitation Client departs: physical tension significantly reduced, movements deliberate/controlled Observable effect: emotional state alteration in ~one hour Quality of effect: consistent with Session 1 pattern

He was beginning to wonder if he was the world's most credulous data scientist or if there was something to observe.

Wren knew she had a new neighbor who paid attention.

She knew it because she'd lived alone for three years and had gotten used to the specific silence of 4A—empty most days, minimal noise most nights. Then three weeks ago that had changed. Footsteps on different schedules than the previous tenant. The sound of fingers on a keyboard at odd hours. A chair shifting slightly against hardwood. And then, in the last week, the subtle marker of awareness: pauses in the ambient noise that matched pauses in her own.

Last Thursday, she'd been midway through clearing energy from a session when she'd heard his footstep in the hallway. Not threatening. Just attentive. She'd continued as she always did, moving through the consulting room with her little bundle of sage, her salt, the precise movements that mattered less for the salt itself and more for the intent it carried. When she finished, she'd glanced toward the shared wall and caught the thin line of his shadow under the door.

He'd moved away.

She'd smiled.

Today, watching the woman leave from her client's strained shoulders and knotted jaw to something softer, she'd felt him watching from somewhere near the stairwell. She didn't look directly at the door. She didn't change anything about what she was doing or how she was being. But she was aware of him in the way she was aware of most things in her world—as a data point in a larger pattern. Someone curious. Someone paying attention. Someone who didn't yet understand that the walls in a Brooklyn brownstone ran both ways.

Her own light would be on late tonight. She had to plan for Saturday's schedule, and her workbooks didn't organize themselves.

The second client left at 3:08 pm. Marcus spent the rest of the afternoon in video calls and email triage, the normal texture of his work, and it all felt like static. He kept thinking about the measurements he'd taken. The precision of his observations. The way each session ended the same way: differently. Someone stepped out of that apartment in a materially altered state.

It wasn't magic. Obviously not. There were a thousand rational explanations. Therapeutic effect. Placebo. A genuine consultant with a real skill for talk therapy or life coaching or whatever it was that happened behind that door. He didn't have a better one.

At 11:47 pm, when Marcus was still at his desk scrolling through papers on proprioception and neuroplasticity—research that felt both relevant and useless—he noticed her light was still on. The window visible from the street-side, not the shared wall, but he'd noticed it before and tonight he was noticing it now.

He turned off his desk lamp.

The room went dark except for the glow of his screen. He was exactly on the line between the apartments, could feel the wall just behind his left shoulder. She was exactly on the other side of it. Six feet, if that. The width of a hallway and some plaster and a century of Brooklyn brick.

He had no idea what her name was.

He didn't know if she was at a desk like him or on a floor surrounded by books or standing in front of an open refrigerator hoping for inspiration. He didn't know if she was the woman with the strained voice or the woman with the knotted shoulders or someone else entirely. He didn't know anything except that she kept her light on at this hour the way he kept his on, and that was a fact worth noting.

He opened the spreadsheet again.

Unknown neighbor (4B) — he typed, then deleted it. Too weird. Too revealing.

Observed occupant, apartment 4B Active hours: highly irregular (2300-0300 range common) Scheduling: pattern suggests self-directed workflow Client contact: active, regular Ambient noise signature: careful, intentional (no idle noise)

He paused, fingers hovering over the keyboard.

Identifying information: None Name: Unknown Visual data: Minimal Working hypothesis: Requires additional observation

He saved the file and closed the laptop.

In the darkness of his apartment, he could still see the line of light under his door—the reflection of 4B's window light in the hallway. Twelve or thirteen hours from now, she'd have more clients. In fifty-two to fifty-three minutes, they'd leave different than they arrived, and he would time it and note it and add it to the spreadsheet, and he still wouldn't know her name.

His phone lit up on the desk. A building notice from the management company, forwarded by the super: 4B was up for lease renewal at the end of the month. The current occupant had thirty days to confirm or vacate.

He looked at the entry still glowing on his screen. Identifying information: None.

He had been watching for three weeks and had collected nothing that mattered. He had thirty days left to change that, and no idea where to start.
