A best-selling author was killed on the night before his departure abroad. The murderer was soon captured, and confessed to his crime and asked for nothing but death penalty, but did not give clear answers to his motive. Was he really the criminal? Why did he kill the author? After thorough investigation of the past between the victim and the killer, the police officer felt a plummeting surge of shivers in front of the seemingly plain facts of the murder.
