The whiteboard smelled like dry-erase marker and stale coffee, which is to say it smelled like every FBI briefing room I'd ever stood in. I uncapped the blue marker — blue for behavioral traits, red for physical evidence, black for timeline — and added a new line under BEHAVIORAL PATTERN.
Subject may be engaged in some form of psychological processing — therapy, journaling, structured self-reflection.
"Walk us through that," Cole said from the back row. He had his feet up on the chair in front of him, which would have looked disrespectful if I didn't know it was the only position that didn't aggravate his bad knee. Three other agents sat scattered across the room. Two were paying attention. One was checking his phone under the table like a teenager in church.
"Kill intervals," I said. I tapped the timeline with the marker cap. "Kills one through eight: average interval, nineteen days. Kills nine through thirteen: twenty-six days. Fourteen through seventeen: thirty-two to thirty-eight days."
"He's slowing down," said Agent Reyes, the one who'd been paying the most attention.
"He's slowing down," I confirmed. "But not degrading. Kill seventeen is his cleanest work. Single round, suppressed, contact distance. No forensic transfer. He wiped the casing before loading — not after ejecting. That's anticipatory, not reactive. This isn't someone losing interest or getting sloppy. This is someone whose internal pressure valve is being released through an additional channel."
Cole tilted his head. "Like what?"
"Therapy. Meditation. A relationship. Something that provides emotional regulation he previously only achieved through the kill itself." I wrote SECONDARY REGULATION SOURCE on the board. "The intervals lengthen because the psychological need that drives the kill cycle is being partially met elsewhere."
"So he's got a girlfriend," said the agent who'd been on his phone. Martinez. He looked up with the particular smugness of someone who thinks he's simplifying.
"Or a therapist. Or both." I capped the marker. "The point is, this is new. Something changed in his life roughly eight months ago that's providing supplementary emotional regulation. If we can identify that change, we narrow the field."
Cole was quiet for a moment. Then he smiled — the dry, tired kind. "Maybe he's your patient, Doc."
The room laughed. I laughed too.
My laugh stopped half a second before his.
Not enough for anyone to notice. Just enough for me to feel the air close over the sound like water over a dropped stone. I turned back to the whiteboard so no one could see my face. Picked up the black marker. Drew a timeline bracket around the last four kills.
"Let's talk victimology," I said, and my voice was exactly right. Clinical. Measured. Dr. Cross at the whiteboard.
I spent the next forty minutes building the profile out loud, piece by piece, the way I'd done for six years. It was the part of the work I was best at — taking scattered data points and assembling them into a human shape. A ghost made flesh through inference.
The Gentleman Killer. The name the media gave him after kill number four, when a journalist noticed that every victim's affairs were in order within forty-eight hours of death. Not because of estate planning. Because someone had gone through their offices. Files organized. Hard drives wiped of anything embarrassing. One victim's browser history was cleared — only the dating sites, not the financial research. As if someone had made a judgment call about what constituted a secret worth keeping.
"He respects the dead," I said. "Not sentimentally. Practically. He cleans up after the kill the way a surgeon closes an incision. The job isn't done when the heart stops. The job is done when everything is in order."
I wrote on the board:
Male, 30-40. Military or paramilitary training. High discipline. Lives alone. Minimal personal attachments — or attachments that are carefully controlled. Presents as normal, possibly charming. No criminal record. Employed in a field that allows flexible scheduling and explains travel. Financial consulting. Security. Independent contracting.
"Physical profile," Cole prompted.
Above-average fitness, maintained through routine, not vanity. Contact-distance shooting suggests confidence in close proximity — he's strong enough to control the situation if the shot fails. Ambidextrous or trained to shoot with either hand (Kill #11, left-hand entry angle). Steady hands. Very steady hands.
"Psychological profile," Reyes said.
I paused. This was the part that mattered.
Compartmentalized emotional architecture. Capable of genuine connection but operates through constructed personas. Low resting anxiety — physiologically calm. Possibly presenting with alexithymia markers (limited emotional vocabulary) or hyper-controlled affect. If engaged in therapy, would present as high-functioning. Pleasant. Cooperative. Resistant to depth without appearing resistant.
