The heavy rain fell in cold sheets against the darkened windows of Blackwood Manor, obscuring the twisted oak trees outside. Inside the great hall, twelve wealthy guests gathered for the annual dinner, unaware that a killer waited patiently among them. Lord Ashworth stood proudly at the head of the long mahogany table, raising his crystal glass for the customary toast. His deep voice carried warmth across the room, but his eyes betrayed the fear that had haunted him for weeks. Lady Ashworth watched her troubled husband with quiet concern, her pale fingers trembling slightly as she lifted the silver fork. The flickering candles dimmed mysteriously when a sudden gust swept through the hall, though every window and door remained sealed. A collective shiver passed through the assembled guests, and conversation died abruptly, leaving only the eerie sound of ticking clocks. Then came the sharp scream from the kitchen, high and terrible, shattering the fragile peace that the old manor offered. When the frightened guests rushed to investigate, they found the head chef lying unnaturally motionless beside his massive iron stove. The long carving knife protruded from his back, and dark blood pooled slowly across the freshly scrubbed stone floor tiles. Behind them, the heavy oak door clicked quietly shut, trapping twelve shocked suspects inside with a murderer still walking free.
