Rain stitched the harbor night. Detective Mara Voss arrived alone. A scream died behind warehouses. Docklights flickered like guilty eyes. She followed bootprints through salt. The pier smelled of copper. Someone lay beneath tarps quietly. Mara lifted one corner carefully. A businessman stared upward, unblinking. His throat wore a key. In his fist, sand glittered. A note whispered, 'Find Lark'. Footsteps retreated across puddles nearby. Mara pocketed the wet note. Then the tide swallowed secrets.
