The relentless rain fell heavily against the tall windows of Blackwood Manor, completely obscuring the jagged silhouette of distant hills. Inside, the usually bustling grand foyer of Blackwood Manor felt strangely silent, completely lacking the familiar sounds of household staff. Mrs. Pettigrew, the longtime housekeeper, moved quickly through the shadowed hallway, her candle casting long, wavering shadows on the walls. She had checked every room on the ground floor, but the master of the house was nowhere to be found. Finally, she pushed open the heavy oak door of the study, and a sharp gasp escaped her trembling, pale lips. Lord Edmund Blackwood lay slumped across his writing desk, a dark crimson stain spreading slowly across his expensive white shirt. A brass letter opener rested near his limp right hand, its polished surface smeared with a thin film of blood. The room smelled faintly of expensive cigars and something else, something metallic and deeply unsettling that made her stomach churn. Detective Sarah Chen arrived precisely forty minutes later, her sharp eyes immediately noting the scattered papers and overturned leather chair. Nothing about the scene suggested a random burglary gone wrong; this was something far more personal and calculated, she realized. The heavy rain had washed away every single footprint outside, meaning the killer was still somewhere inside the sprawling manor.
