Moonlit ballroom hummed softly, late. Guests whispered, unaware of danger. A chandelier flickered, casting shadows. Suddenly, a scream pierced silence. The clock struck twelve, ominously. Portrait's eyes seemed to follow. Footsteps echoed through empty corridors. Body lay in dark ballroom. Detectives arrived, their faces grim. They questioned guests, searching clues. The night held many secrets.
