又使我们成为国民，作他父神的祭司。但愿荣耀、权能归给他，直到永永远远。阿们！（启示录1：6）And made us a kingdom , priests to his God and Father , to him be glory and dominion for ever and ever . Amen . ( Revelation 16 )
该剧根据1996年前FBI探员约翰·道格拉斯（JohnDouglas）和马克·欧夏克（Mark Olshaker）的著作《心理神探：美国联邦调查局系列犯罪破案揭秘》（MindHunter Inside the FBI's Elite Serial Crime Unit）改编。退休后的道格拉斯深入研究犯罪心理学，美剧《汉尼拔》（Hannibal）和《犯罪心理》（CriminalMinds）中的角色刻画也参考了书中的很多案例。
Henry Fallon, who is wheelchair bound and is suffering from a neurological disorder, apparently commits suicide and Morse has mixed feelings working on this case as he was once engaged to the dead man's wife, Susan Fallon. The body was found by his son-in-law Peter Rhodes, a local antiques dealer and the victim's wife was in London. When Fallon's doctor advises Morse that Henry didn't have the physical capability to hold a gun to his head, the police realize they may have a murder on their hands. When the police are told that the business arrangement between Fallon and Rhodes had fallen apart, they also have a suspect. Lewis is concerned that Morse is too close to Mrs. Fallon to be objective but in the end, the perpetrators are identified.
