Cold rain lashed against the cracked window of the library. Lord Harrington lay motionless across the antique mahogany writing desk. Thick red blood dripped slowly onto the expensive Persian rug. A silver letter opener protruded sharply from his frail chest. Every ancient grandfather clock chimed midnight throughout the quiet estate. Detective Miller stepped carefully into the shadows of the room. The locked safe behind the oil painting stood wide open. Someone inside this stormy mansion had committed the perfect crime.
