The rain hammered Blackwood Manor as Detective Mara Voss arrived to find the old colonel dead beside his untouched breakfast. Silver candlesticks framed the body while one window stood open despite the storm and every servant swore doors were locked. Mara noted mud indoors no footprints outside and a clock halted at midnight though its mechanism seemed freshly wound tight. The heir paced downstairs the maid wept into her apron and the butler answered every question with polished rehearsed evasions. Somewhere upstairs a floorboard sighed though nobody admitted moving and Mara understood the house itself had begun lying to her.
