Alien Hearts is the last novel that Maupassant wrote before he died, aged 43. It's the story of a wealthy man who becomes hopelessly infatuated and then deeply in love with a society woman. This woman has survived an abusive marriage and, as a result, cannot love him the way he wants her to. He finally leaves her to seek solace in the countryside but cannot get her out of his mind. Whilst there he falls in love with a servant girl, who can love him the way he wants. The society woman comes after him and the book ends on a question mark as to the future of them all.
Excellent prose, excellent translation and an excellent story. Well worth reading.
ETA I read the NRYB Classics version as translated by Richard Howard, the first translation in more than 100 years apparently
