Rain silvered the harbor as Mara Voss found the body beneath the pier just before dawn broke over Blackwater Bay. The victim wore a velvet coat one shoe and a cryptic ticket stub marked midnight inside his frozen left hand. Detective Ilan Crow arrived late because the bridge had closed again trapping fishermen reporters and one nervous mayor outside town. Everyone swore the lighthouse keeper slept early yet his lamp burned green while the tide erased footprints from the sand. Mara photographed a bruise shaped like an anchor then noticed salt rosemary and lipstick glittering along the dead man's collar. A church bell rang six times though the tower stood empty and every door in the village locked from within.
