At midnight, the lighthouse bell rang without any human hand. Detective Mara Voss watched fog swallow the entire empty harbor. Below, Mayor Thorne lay dead beside a shattered brass compass. His blood traced an arrow toward the locked boathouse door. No footprints marked the frost surrounding his polished black shoes. Mara knelt, noticing seawater glittering inside the dead mayor's pockets. A gull screamed once, then dropped something onto nearby stones. It was Mara's missing key, still warm with fresh blood. Behind her, the boathouse door began creaking open by itself. Someone inside whispered, “You arrived earlier than I expected tonight.”
