Rain soaked the cobblestones beneath the gaslight's wavering orange glow. Detective Rowan arrived, hat dripping, coat heavy with wet dread. They found her sprawled, fingers curled around a jeweled locket. No visible wound, only a pale face and closed eyes. A smear of blood stained the hem of her gown. Neighbors whispered behind curtains; candles flickered like guilty little secrets. Rowan pocketed a single glove, already imagining the tangled motives. Somewhere a clock chimed three; footsteps receded into sodden night.
