Mémoires de deux jeunes mariées
Louise is expected to sacrifice herself for her two brothers and take the veil, but the young girl refuses to submit to such a fate. Her dying grandmother intercedes on her behalf and bequeaths her her fortune, thereby rescuing her from the enclosed life of a Carmelite nun and leaving her financially independent. Free to assist her brothers financially without having to sacrifice her own ambitions, Louise settles in Paris and throws herself into a life of Italian operas, masqued balls and romantic intrigues. She falls in love with an unbecoming but noble Spaniard, Felipe Hénarez, Baron de Macumer. Banished from Spain, he lives incognito in Paris where he is forced to support himself by teaching Spanish. When he regains his fortune and noble standing, he woos Louise with a romantic fervour that finally wins her over. The pair are married in March 1825. They live a life of carefree happiness, but Louise's jealousy embitters him and leads to his physical break-down. He dies in 1829, leaving a grieving widow of twenty-four.
