Midnight rain hammered the slate roof, and a lone figure lingered beneath a tattered umbrella, trembling outside the ancient manor. Inside the dimly lit ballroom, twelve acquaintances raised crystal glasses, exchanging nervous laughter while thunder rattled the chandelier overhead ominously. At midnight, a bloodcurdling scream shattered the hall, its echo lingering as trembling guests exchanged horrified glances in deadly silence. Inspector Marlowe entered, coat soaked, eyes scanning the scene, noting the crimson stain on mahogany table and missing candelabra now. Lord Ashworth, the wealthy host, lay slumped across his chair, his eyes forever frozen in a final, desperate plea still.
