The grand library stood completely silent, save for the clock. Lord Ashworth lay quite dead upon the large Persian rug. One single gunshot wound marred his otherwise pristine evening wear. The butler discovered the scene, his face a pale mask. The cold moonlight streamed through tall windows, illuminating the scene. A shattered brandy glass lay near his outstretched left hand. The room smelled of old books, whiskey, and something metallic. No weapon was visible anywhere within the shadowy, book-lined room. The heavy library door slowly creaked open behind the butler. A figure stood there, silhouetted in the bright hallway light.
