Rain pounded relentless against the stained glass windows, masking the faint sound of the front door slowly creaking open. Detective Marcus Vance stepped onto the polished mahogany floorboards, brushing cold water off the collar of his heavy trench coat. A single brass candlestick lay shattered upon the velvet carpet, its melting wax sealing a dark and gruesome secret. Lord Harrington sat slouched in his wingback armchair, an ivory-handled letter opener buried deeply within his once noble heart. The grand mantle clock ticked with steady precision, oblivious to the horrific violence that had just transpired in this room. Vance knelt beside the corpse, carefully pulling out his magnifying glass to inspect the unusual powder scattered around the victim. A half-empty glass of amber whiskey rested upon the side table, completely untouched by any trace of drifting dust. Outside the manor, a sudden flash of lightning illuminated a fleeting silhouette disappearing rapidly into the dense surrounding forest.
