Rain hammered the empty pier. Detective Mara Venn arrived alone. A lantern swayed above water. Beneath it, something pale floated. She stopped beside the railing. The corpse wore her coat. A knife protruded from him. Inside its pocket, something ticked. Then the lighthouse went dark. A whistle blew behind her. She turned, drawing her revolver. Only rain crossed the boards. Then someone whispered her name.
