Heavy rain lashed against the cracked windowpane of the manor. Lord Harrington sat motionlessly inside his grand, dimly lit study. A half-empty glass of amber whiskey rested upon the desk. The grandfather clock chimed midnight with a dark, haunting echo. Suddenly, a muffled gasp shattered the silence of the room. Harrington collapsed forward, his heavy head striking the polished mahogany. A silver letter opener was buried deeply into his back. Blood pooled slowly across the delicate, hand-woven Persian rug. Shadows danced eerily as the fireplace flickered its last ember. Out in the hallway, quiet footsteps rushed into the darkness.
