One thinks of how Alfred Hitchcock would have staged this ice heroin, hermetic, which retains its mystery that refuses to explain, but that leaves gradually discover. Blonde, elegant, sporty, well-shaped features (this is the image of her that forms on my own screen), it is both horrifying and painful. She is a woman of our time, faced with recurring problems of our society, obsessive desire for children, independence in the couple, solitude in the end. She confronts one, why? We cling, we try to understand is a "thriller". It approves Claire, you hate it, but do not we drop the book to the final stupor.
