The Four Sides of the Heart is the last novel by Françoise Sagan, who died in 2004. Her son Denis Westhoff discovered a typewritten copy riddled with insertions and corrections in the writer’s archive. This is a novel written in a free, uninhibited manner, with amazing skill and attention to human passions. The writer's intellect, sense of humor and elegance of style allowed her to convey the dramatic twists and turns of the plot in such a lively and laconic manner that the reader enjoys immersing herself in the atmosphere of this unfinished and thus exciting narrative. The son of a wealthy industrialist, Louis Cresson, having recovered from the consequences of a car accident, is surprised to realize that his family looks at him with caution, as if he were nervous, and his beloved wife Marie-Laure completely despises him. The situation changes when the beautiful Fanny, Marie-Laure's mother, arrives from Paris. To convince everyone of Louis' recovery, the Cressons organize a magnificent reception at their estate, while passions heat up.
