Set in the early 1920s, the book centers on Augustine, a young man from an aristocratic Welsh family who has come of age in the aftermath of World War I. Unjustly suspected of having had a hand in the murder of a young girl, Augustine takes refuge in the remote castle of Bavarian relatives. There his hopeless love for his devout cousin Mitzi blinds him to the hate that will lead to the rise of German fascism. The book reaches a climax with a brilliant description of the Munich putsch and a disturbingly intimate portrait of Adolph Hitler.
