Fear

Finding her comfortable bourgeois existence as wife and mother predictable after eight years of marriage, Irene Wagner brings a little excitement into it by starting an affair with a rising young pianist.

Written in the spring of 1913, and first published in 1920, this novella is one of Stefan Zweig’s most powerful studies of a woman’s mind and emotions.

La Paura (1954) the Roberto Rossellini film based on the Stefan Zweig novel Fear was the last of the extraordinary features in which Rossellini directed Ingrid Bergman, who was then his wife.
