Rain stitched the harbor to the blackened pier that night. Detective Mara Voss arrived before the sirens finished dying completely. The victim lay beneath damp canvas, pale as warehouse snow. One silver cufflink still glittered beside the victim's open hand. Nobody remembered hearing shots, only gulls arguing over bread nearby. Mara noted the tide retreating, careful, almost apologetic, slow tonight. The watchman swore he locked every gate at midnight sharp. His lantern smoked, though the wind had died hours earlier. Inside the office, dusty ledgers fanned open like guilty wings. Someone had carefully circled tomorrow's date in red ink twice. Mara pocketed the cufflink and promised the dead answers tonight. Outside, the harbor swallowed its first uneasy secret before dawn.
