Today we're talking about a book, "La beauté du ciel", which begins with a phone call in May 2017 to a young woman who's told by the police that her mother's grave has been desecrated. Her mother died 35 years before when the woman was just four years old. Three weeks after the phone call, she falls pregnant with her first child. The mother in the story is the Austrian-born actress Romy Schneider, who died in Paris in 1982 aged 43. The daughter and author of the book is the actress Sarah Biasini.
