The old mansion loomed under a stormy sky, its windows dark and foreboding like unblinking eyes. Footsteps echoed faintly inside, growing louder as someone approached the grand oak door creaking open slowly. A cold draft swept through the hallway, extinguishing the lone candle flickering precariously on the dust-covered table. Shadows danced ominously along the walls, twisting into shapes that seemed to reach out menacingly. A faint metallic scent hung in the air, mingling with the musty odor of neglect and decay. At the end of the corridor, a figure lay unmoving, their pale hand stretched toward the staircase. Blood pooled beneath the body, spreading slowly across the cracked marble floor like a dark, silent tide. A single white lily rested beside the corpse, its petals pristine and untouched by the surrounding chaos. The silence was deafening, broken only by the distant roll of thunder from the brewing storm outside. A faint whisper echoed through the halls, carrying words too indistinct to understand but chilling to the core. Somewhere in the mansion, a clock began to chime, its hollow tones marking the hour with unsettling precision. The sound of glass shattering upstairs shattered the stillness, followed by hurried footsteps retreating into the darkness. A faint glimmer of light appeared briefly in a second-story window before vanishing abruptly into the night. The storm outside intensified, rain pelting the windows as lightning illuminated the mansion’s crumbling facade briefly. Within moments, all was still once more, as if the house itself held its breath in anticipation. And so, the stage was set for a mystery that would unravel secrets long buried.
