Severine Serizy is a wealthy and beautiful Parisian housewife. She loves her husband, but she cannot share physical intimacy with him, and her vivid sadomasochistic fantasies drive her to seek employment at a brothel. By day, she enacts her customers' wildest fantasies under the pseudonym 'Belle de Jour'; in the evenings, she returns home to her chaste marriage and oblivious husband. Famous for its unflinching eroticism, Joseph Kessel's novel continues to offer an eye-opening glance into a unique female psyche.
