Four Sides of the Heart is the last novel by Franoise Sagan, who died in 2004. Her son Denis Westhoff found a typewritten copy in the archive of the writer with inserts and amendments. This is a novel written in a free, relaxed manner, with amazing skill and attention to human passions. The writer’s inherent intelligence, sense of humor and elegance of style allowed her to convey the dramatic twists of the plot in such a lively and concise manner that the reader gets pleasure by immersing himself in the atmosphere of this unfinished and thereby exciting our imagination of the narrative. The son of a wealthy industrialist, Louis Cresson, recovering from the consequences of a car accident, is surprised to realize that his family is wary of him, as if he is nervous, and his beloved wife Marie-Laur completely despises him. The situation changes when the beautiful Fanny, mother of Marie-Laure, arrives from Paris. To convince everyone of Louis's recovery, the Cressons start a lavish reception at their estate, and passions meanwhile heat up.
