The last ferry to Isle Marin had cleared the breakwater at eleven, and the terminal should have been a box of echoes and wet light. Instead, just after dawn, a sweeper found Walt Dennison on the floor and ran for the harbor master.

By the time the file reached the Civic Archive, the rooms had been cleared and Walt had been taken up the hill. What remained was paper: four names, four rooms, four objects logged out of the building, and a harbor master who wanted the rumor settled before the afternoon paper.

Linnea Maki set the folder square to the desk edge, uncapped her pen, and drew a grid. She had walked past the terminal every workday for nine years. She knew the ticket booth’s sticky drawer, the canteen’s burnt-coffee air, the baggage cage with its chicken-wire shine, and the fuel dock’s rainbow sheen on black water. She also knew Walt: careful with keys, short with late passengers, and kind to the morning bread delivery.

Four people had after-hours business in the terminal. June Harlow, who worked the day window, had come back about a till that would not close. Tomas Reid had been on the dock for a late repair. Priya Shah had left the morning bread and, she said, a word for Walt. Ellis Boone, a harbor pilot held in port by weather, had wanted a key he claimed was his. Linnea wrote the four names down and began.
