Detective Jameson arrived at the mansion at precisely nine o'clock. Murder was suspected, and his expertise was greatly needed here. The butler led him to the library with nervous fingers. Jameson's eyes scanned the room, taking in every detail slowly. Lord Harrington's body lay on the expensive Persian carpet quietly. The victim was dressed in his finest evening attire formally. His eyes were frozen in a look of great horror. A thin line of blood trickled from the corner slowly. The detective's trained gaze swept the room again carefully now. A piece of paper clutched in the victim's hand tightly.
