Rain stitched the night's black. Streetlamps hummed like dull witnesses. A body floated near pier. Hands splayed, gloves stained dark. Someone had called the police. Detective Larkin arrived before dawn. He tasted salt and guilt. Fog wrapped the quay tightly. A glint suggested a clue. Shoes left prints in mud. A locket lay half submerged. The photograph inside showed smiling. Larkin's eyes narrowed, memorized faces. Footsteps approached from the darkness. A witness emerged, voice trembling.
