Linda's hands tightened, just slightly, and her face did the fastest rearrangement yet: confusion, then offense, then a careful blankness that was not quite either. "I did not write those," she said. "I received concerns from neighbors. I passed concerns along. That is what a watch captain does."
Ruiz asked who had given her the concerns, and Linda named no one specifically. She spoke of the group chat, of messages, of people who were worried but did not want to be named. Ruiz asked whether those messages had been saved, and Linda said she did not keep everything, that a watch captain passed things on and moved to the next concern. She admitted watching the house. She admitted keeping a notebook. She admitted cutting the lock. She did not admit writing the envelopes, and Ruiz did not press her into a corner she could not yet prove. Instead, Ruiz asked Linda to describe, step by step, how a concern reached her and how it reached Marcus's mailbox, and Linda's account grew vaguer with each step, as if the middle of the process — the writing, the printing, the delivery — had happened somewhere she could not quite look. The interview ended with Linda still composed, still offended, still convinced that her intentions should have mattered more than her actions. Ruiz walked her back through the corridor and thought about the distance between an admission and an explanation. Linda had given the first. She had not yet given the second, and Ruiz suspected she would not give it until the paper in her own house was laid on the table in front of her.
The warrant for Linda Harper's home office was narrow, and Detective Ruiz liked it that way. It named the office at 1152 Briarwood Lane, the papers and devices related to the envelopes and the reports about 1147, and nothing else. Ruiz read it twice before she left the station, checked the address against the file, and briefed the officers who would go with her: no bedrooms unless the warrant said so, no drawers opened for curiosity, everything photographed where it lay before it was moved. A search that overreached would help Linda more than it helped the case, and Ruiz had no intention of giving her that gift.
Linda was not home when they arrived. She had been told, through her lawyer, that a search would take place, and she had chosen not to be present, which Ruiz respected and also noted. The house was quiet and tidy in the way of a house kept by one person with routines. The office was at the back, a small room with a desk, a filing cabinet, and a printer on a stand beside the window. Sunlight fell across the desk in a clean rectangle. On the desk, beside a notebook bound in dark cloth, lay a stack of white paper.
Ruiz photographed the stack before she touched it. The paper was the same size, the same weight, the same faint texture as the paper of the envelopes in evidence. She did not need a laboratory to see the resemblance, and she did not claim more than resemblance at that moment, but she felt the case shift under her hands. She lifted one sheet, held it to the light, and compared it in her mind to the envelope she had sealed the day before. The match was close enough to seize, and seizing was what the warrant allowed.
The notebook, when she opened it, was Linda's record in her own hand: dates, times, cars, packages, lights, all written in the same careful script, all about 1147. The entries ran for three weeks and then stopped, abruptly, on the afternoon of the lock, as if the writer had run out of things to observe and had decided to act instead. Between the pages, Ruiz found a loose sheet, folded once, in the same handwriting. It was a draft, unsent, and it read, in full: "He is dangerous. Act before someone gets hurt."
Ruiz photographed the draft where it lay, then bagged it with the notebook and a sample of the paper stack. She did not read triumph into the find. She read procedure into it: photograph, bag, seal, log, chain of custody, the same steps she had used for the cutters on the porch and the envelopes in Marcus's folder. The printer, too, was documented — its make, its model, the paper tray still holding the same stock — so that the comparison she had requested could be run properly, against a known machine, rather than guessed at. In the filing cabinet, Ruiz found copies of Linda's three non-emergency reports, filed in chronological order, and printouts from the watch group chat in which Linda's own messages about 1147 appeared again and again. The office window looked directly toward the street, and from the desk chair, Ruiz could see the roofline of 1147 across the way. She photographed that view as well, not as proof of a crime but as context: this was the room from which the street had been watched, and the desk from which its worries had been written down.
