The old mansion loomed ominously against the stormy night sky. Detective Sarah Parker stepped out of her car, raindrops pelting her. Lightning flashed, illuminating the grotesque gargoyles adorning the weathered facade. She approached the grand entrance, her footsteps echoing on wet pavement. The door creaked open before she could knock, revealing darkness within. A butler, pale and trembling, ushered her into the dim foyer. "It's upstairs," he whispered, pointing to the grand circular staircase. Sarah ascended slowly, her hand resting on her holstered gun. The lightning flashed again, casting eerie shadows along the walls. At the top, a door stood ajar, spilling light outside. She pushed it open, revealing a luxurious study in disarray. In the center lay a body, surrounded by a pool of blood.
