Rain polished the empty promenade. Inspector Mara Voss arrived alone. Beneath the pier, gulls screamed. A violinist lay among seaweed. His white gloves remained spotless. No blood stained nearby sand. Mara knelt beside the body. One pocket held a seashell. The other contained her photograph. Across it, someone had written. “Remember what happened last winter.” Footsteps clicked above the pilings. Mara looked up too late. Only fog crossed the railing. The dead man’s watch chimed. It announced tomorrow’s midnight hour.
