Fog curls around old docks. Cold seeps through rotting pilings. First mate misses his check-in. Coast guard boards at dawn. Bloodstained planks hold cold flesh. Knife hilt juts from ribs. No ID lies on him. Locked cabin door hangs ajar. Crumpled note rests on sill. One name scrawled in ink. Salt wind snuffs lantern glow.
