"Four Corners of the Heart", an unfinished 200-page story by the author of "Bonjour Tristesse" – which caused a sensation with its portrayal of the empty lives of the idle rich – was found by her son Denis Westhoff after her death in 2004.
Like her debut novel, which Sagan wrote at 17, the latest release is a laconic dissection of the lives of the haute bourgeoisie. It is centred on an unusual love triangle involving Ludovic Cresson, a businessman who made his fortune in vegetable production. But, like Sagan, he has a serious car accident, and then becomes amorously entangled with his mother-in-law.
