Night swallowed the coastal town. Fog licked the lamplight's edge. A body floated beneath pier. Red stained the wooden boards. Detective Hale arrived, coat drenched. He studied footprints leading away. Neighbors clustered, whispering dead names. Moonlight revealed a bloody note. It read only one sentence. Forgive me, it began simply. A single name was circled. Hale felt the wind shift. Footsteps approached from the darkness. He tightened grip around flashlight. A voice warned from behind. Hale spun, flashlight cutting silhouettes. Silence swallowed the threatening words. He noticed fingerprints on railing. One print matched the dead. Hale studied the circled name. It was her maiden name. A secret returned with tide.
