The rain hammered the cobblestone streets, echoing midnight whispers softly. Inside the manor, a chandelier fractured, spilling light across marble. A lone portrait stared back, eyes following every trembling footstep. The clock struck thirteen, and the scream shattered silence forever. Detective Marlowe arrived, notebook in hand, eyes scanning shadows coldly. He found the body, a crimson stain on the floor.
