The grand ballroom glows with candlelight as whispers fill the air tonight, Elegant gowns shimmer under chandeliers, each guest hiding secrets well-kept. A shadowy figure slips past the crowd, clutching a single, bloodstained handkerchief. The orchestra plays a haunting melody, but no one dares to look behind them. A sudden scream echoes through the hall, startling guests who freeze in terror’s grip. The victim lies sprawled across the marble floor, her throat slit in cold, deliberate strike. The butler stands rigid, his face pale, as he watches the chaos unfold before his eyes. No one knows who killed her, though whispers spread like wildfire through the elite crowd. The detective arrives, his sharp eyes scanning the room for clues hidden in plain sight. Every guest has motive, every secret could be the key to solving this dreadful crime tonight.
