One woman is so bored with her marriage, she decides to work in a brothel when her husband is gone. 

Imagine you had a wife who was so bored with her bourgeois marriage that she decided to work in a brothel during the day to indulge in her sadomasochistic fantasies. If this sounds shocking today, imagine how it was received by the world when it was first published in 1928. The book that inspired the famous Luis Buñuel film is a bit of a quaint read, but it's also titillating and deeply psychological. As the author explained in the foreword: “With 'Belle de Jour' I tried to show the terrible divorce between the heart and the flesh, between a true, deep and tender love and the implacable want of carnal senses.”
