The cold rain hammered the rooftops of Blackwater Lane as Detective Clara Voss arrived at the old Whitmore estate grounds. Yellow tape fluttered around the grand entrance while officers milled about, their faces pale beneath the dimly flickering porch lights. She ducked beneath the yellow tape and stepped inside where the scent of death hung heavy in every single room. The victim, Lord Reginald Whitmore, lay sprawled across the Persian rug, a silver letter opener buried deep in his chest. His glassy eyes stared at nothing while his outstretched hand seemed to point toward something just beyond the fireplace mantel. Voss knelt carefully beside him and noticed something strange: his pocket watch had stopped at exactly midnight, the witching hour. On the grand mantelpiece stood a crystal decanter half-filled with brandy and a handwritten note scrawled in trembling, ink-stained handwriting. She picked it up carefully and read the cryptic message written there in dark, smeared letters on the yellowed paper. 'The blood debts of this house will finally be settled,' it declared, as though the writer had been waiting years. Outside, thunder cracked across the darkening sky and the lights in the old manor house suddenly flickered, then died completely. For a breathless moment, the only sounds were the rain and the detective's own heartbeat echoing through the empty room. Then, from somewhere deep within the house, a floorboard groaned under the weight of someone who refused to remain hidden.
