The Hangman's Demise

A former hangman, Henry Lee, is confronted at his wedding anniversary by a mother about her son whom he executed a year before for the murder of a court secretary - an execution where the condemned man whispered to Lee the identity of the real killer. The following morning Lee is poisoned with hemlock. His friend George, an ex-policeman, is arrested and released. The mother, recently released from prison, is arrested and a motive for Lee's wife emerges. Father Brown untangles a web of deceit and corruption in the police as Lee lays dying.
