The foggy night cloaked the abandoned manor, its ancient stone walls echoing with distant, mournful whispers in the moonlight silently. Inside, the grand ballroom lay empty, save for a single candle flickering beside a polished marble table. A shattered portrait stared down upon the floor, its eyes now blank, reflecting the room's empty silence in the gloom. Suddenly, a bloodcurdling scream pierced the silence, echoing from the hallway towards the foyer as the lights flickered brightly softly. The police arrived moments later, their boots thudding against marble, eyes scanning for any sign of life in the foyer. Detective Marlowe stood at the crime scene, her notebook open, scribbling notes about the shattered portrait on the floor still.
