Ojciec Brown Sezon 4 Odcinek 9: The Sins of the Father

Robert Twyman a leading aeronautics magnate receives a note that his son, a piano player and contestant in a local variety show, would be killed. Next morning the son is found strangled next to his piano, in a locked house with only his father and butler present. Twyman is convinced a journalist and his son's rival piano player are the killers. Inspector Mallory arrests Twyman after Lady Felicia finds him standing over the dead body of the journalist. Father Brown notices both pianists had been playing the same music, and the answer is in a book given to him by Doctor Mordaunt Jackson; a psychoanalyst in Kembleford giving a lecture.
