This week on the Book Club podcast, Sam is joined by the veteran foreign correspondent Michela Wrong to talk about her new book Do Not Disturb: The Story of a Political Murder and an African Regime Gone Bad. While Rwanda's president Paul Kagame has basked in the approval of Western donors, Michela argues, his burnished image conceals a history of sadism, repression and violent tyranny. She tells Sam what our goodies-and-baddies account of Rwanda's genocide missed, and why it urgently needs correcting.
