Here is a legendary novel, found in a trunk and published posthumously. It was written during the 19th century but inspired by the epistolary novels of the 18th century. This small, delicate masterpiece transports us to the fascinating era of the Enlightenment. Sixty years after the death of the Duchess of Vaneuse, someone reviews her papers and reveals a story of impossible love: the one that kidnaps the life of a woman as sophisticated as she is intelligent, as ironic as she is melancholy.
