Bestselling author John Boyne joins Paul Smith in the Penguin studio to talk about his latest novel The Heart’s Invisible Furies. John brings along objects including models of Tintin and Pinocchio, a picture of his home and a selection of his favourite books as he talks about setting his novel in his native country, attitudes towards same-sex marriage in Ireland, his lifelong stationery fetish and why you have to be a reader before you can be a writer. #PenguinPodcast
