Rain lashed against the tall windows of the grand manor. Lord Harrington sat silently inside his dimly lit private study. A half-empty glass of expensive scotch rested upon the desk. The grandfather clock chimed midnight with twelve slow heavy strikes. Shadows stretched long across the room as a candle flickered. Suddenly a sharp knock echoed from the heavy oak door. Harrington froze in his armchair and gripped the silver cane. No visitor was expected at this late and stormy hour. He slowly stood up to face the dark looming doorway. A gloved hand pushed the door open without a sound. The sudden flash of steel gleamed bright in the dark. One single muffled gasp escaped from his cold bleeding lips. Harrington collapsed onto the Persian rug with a thud. His killer vanished quietly into the long and empty hallway. The golden pocket watch slipped softly from his lifeless fingers.
