The freezing rain lashed against the tall manor windows as the grandfather clock chimed midnight in the dark, silent hall. Lord Harrington lay slumped across his mahogany desk, a silver letter opener protruding from his back near his cold shoulder. A single red candle flickered on the mantle, casting long and twisted shadows over the lifeless body on the floor. The heavy oak door creaked open slowly, revealing a masked figure standing in the doorway with a very sharp blade. Nobody else in the house had heard the muffled scream that signaled the end of a very wealthy man's life.
