The storm raged fiercely outside the old mansion, lightning illuminating shadows that danced against the creaking wooden walls. Detective Harper stepped inside, their coat dripping rainwater, eyes scanning the dimly lit room for any signs of disturbance. A shattered vase lay near the grand piano, petals of wilted roses scattered, hinting at recent, violent confrontation unknown. From the library, muffled voices echoed softly, tension thick in the air as secrets waited silently to be revealed. Suddenly, a blood-curdling scream pierced the night, forcing Harper to quicken their pace toward the source, heart pounding heavily.
