Rain pinned the seaside town beneath a shroud of sound. Detective Mara Voss found the mayor beside the frozen carousel. His silver whistle held one red hair and no blood. Every clock above the pier stopped at eleven thirteen sharp. A child's paper boat circled the black drain without sinking. Mara tasted copper and heard laughter behind the wet seawall.
