The rain hammered against the stained glass windows while the grandfather clock chimed midnight in the silent, cold manor hallway. Lord Harrington lay facedown upon the Persian rug with a silver letter opener protruding sharply from his broad, velvet back. A single puddle of dark crimson blood expanded slowly across the intricate patterns woven into the expensive and ancient fabric. The young maid screamed when she discovered the cooling body while she was carrying the evening tray of Earl Grey. Porcelain shards scattered everywhere like broken white petals as the heavy silver service hit the floor with a loud bang. Detective Miller stepped through the heavy oak doors and shook the cold raindrops from his gray and weary woolen coat. No guest heard the front door open, but they all felt the sudden chill that swept into the stifling library.
