Fog crept silently over the abandoned mansion’s cracked stone steps. Inside, the grand chandelier swayed, casting eerie shadows on walls. Detective Harris arrived, notebook in hand, eyes scanning every corner. A chilling scream echoed softly, freezing time within the old house. On the marble floor, crimson stained a shattered glass’s sharp edge. Whispers filled the air, secrets tangled in the midnight’s heavy silence. No one moved; each breath held stories of fear and betrayal. The clock struck midnight, signaling a deadly game about to begin. Harris knelt beside the body, searching for clues left behind. Outside, rain began to fall, washing away footprints and hidden truths.
