This week we're looking the possibilities of looking back. Joining Ian McMillan are... Novelist and essayist Tim Winton has been twice shortlisted for the Booker prize for his novels 'The Riders' and 'Dirt Music'. In his new book 'The Boy Behind the Curtain: Notes From an Australian Life', he returns to his childhood. The comedian Stewart Lee has honed the art of the callback over a long career writing for television and radio alongside his stand-up touring schedule. Angie Hobbs is the Professor of the Public Understanding of Philosophy at the University of Sheffield. It's been many years since she's read Milan Kundera's cult classic 'The Unbearable Lightness of Being', and we've asked her to return to the text. Bea Roberts wrote and performed 'Infinity Pool', a modern retelling of Madame Bovary and a hit at the 2016 Edinburgh Fringe. For The Verb, we've asked her to tackle the language of the Tripadvisor review. Producer: Faith Lawrence.
