Rain stitched the city into a coat of watery light. A scream unfurled near the harbor, then silence swallowed everything. Officer Marron found the body beneath a lamplight's jaundiced glow. Blood mapped a slow, ritual curve across the cobbles, gleaming. A pocketwatch lay open, its hands frozen at exactly midnight. Neighbors gathered like moths, whispering alibis and fabricated truths nervously. Detective Liao arrived, trench coat damp, eyes sharp and tired. She knelt, noting footprints, cigarette ash, and a monogrammed handkerchief. Moonlight outlined the docks like a blade against the black. Someone had called it an accident; she called it murder. The town clock chimed once, a witness with small teeth. She rose, pockets heavy with questions and damp cigarette smoke.
