A silver dagger protruded sharply from his heavy velvet vest. Fresh crimson blood slowly dripped onto the cold oak floorboards. Outside, heavy autumn rain battered violently against the tall windows. Detective Miller stepped carefully into the shadows of the doorway. He flicked his brass lighter, revealing another chilling, hidden secret. The locked study door had been opened from the inside.
