Detective Miles arrived at the gloomy mansion on the hill. A single light burned in an upstairs window, flickering weakly. The heavy oak door creaked open to reveal utter darkness. Inside, the air was thick with dust and heavy silence. A shape lay on the Persian rug near the fireplace. It was the body of Sir Reginald, quite clearly dead. A silver letter opener protruded from his chest, gleaming dully. No one else seemed to be present in the house.
