Rain hammered the cobblestones as Detective Marla entered the dimly lit manor, clutching a crumpled invitation that had been delivered. A cold wind whispered through cracked windows, scattering wilted roses across the marble hallway, where shadows lingered like ghosts watching. Inside, the grand ballroom lay deserted, its crystal chandelier dimmed, reflecting only the faint outline of a shattered mirror on. Marla's flashlight trembled, revealing a crimson stain spreading from the floorboards, forming an ominous, irregular pattern across the tiles now. A distant clock struck midnight, echoing through empty corridors, as a faint scream lingered, swallowed by the oppressive silence still.
