A single body lies upon the library's cold and ancient marble floor its eyes open staring blankly at the ceiling. The victim was Lord Ashworth known for his wealth and his many personal scandals a fatal wound upon his chest. His right hand gripped a torn and carefully folded letter from the desk that had no signature written upon it. The elderly housekeeper found the body and screamed a loud and piercing cry that echoed through the mansion stone walls. The butler arrived running quickly to the room's heavy oak door and stopped when he heard the elderly housekeeper cry. He saw the body lying still upon the floor with its eyes staring blankly at ceiling high above this room. The butler called the police and told them about the dead man on the library's cold marble floor right now.
