The old mansion stood silent against the stormy night, its windows like vacant eyes watching the chaos outside. Detective Miller approached cautiously, his hand resting on the weapon holstered beneath his dark coat. The rain lashed violently against the iron gates as thunder rumbled ominously in the distance. A single light burned brightly in the third-floor window, casting an eerie glow across the wet cobblestone path. The butler met him at the door with a face as pale as the moonlight filtering through the storm clouds. "Sir," the butler whispered nervously, "there's been a terrible accident in the study tonight." The detective's eyes narrowed immediately as he stepped inside, his senses alert for any sign of trouble. The air hung thick with silence and the unmistakable scent of fear that permeated every corner of the house. Something terrible had happened here, and Miller was determined to uncover the dark secrets hidden within these ancient walls.
