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.
