Moonlit manor creaks under silence. Guests whisper, eyes darting together. Wind howls through cracked windows. Clock strikes midnight, shadows lengthen. Silence clutches the ballroom still. Suddenly, a scream echoes deep. Footsteps thunder, doors slam. Body lies in center floor. Detective enters, eyes sharp.
