French-Moroccan writer Leïla Slimani joins Harriett Gilbert in the Radio Theatre at the BBC and readers from around the world to talk about her novel Lullaby, the devastating story of a nanny, Louise, who kills two children in her care. The book – an international bestseller – opens with this horrific crime then travels back in time to discover why an apparently perfect nanny turned into a cold blooded murderer. Through the lives of Louise and her employers, Slimani explores Paris’s economy and society, depicting a city where poverty and wealth live side by side and people know little about one another. The third programme in World Book Club’s year celebrating international women’s writing, this novel raises urgent questions about women’s lives and maternal instincts, and what is expected of them.
