Mariella Frostrup talks to French-Moroccan novelist Leila Slimani whose book Lullaby caused a sensation in France and won the Prix Goncourt, and is now being published in English. In it, she explores what would drive a hardworking, dedicated nanny to commit the most heinous of crimes.

Also on the programme, Laura Shapiro discusses her new book What She Ate and explains why she thinks our diets are very revealing about our personalities; Leo Benedictus argues that novels are inherently sinister and Mariella discusses the literary culture, and restrictions on freedom on speech and creativity, in Turkey and Russia - part of Radio 4's Reading Europe series.
