Start the Week is at the Brighton Festival. Stephanie Flanders talks to Michael Rosen about why the 1929 children's novel, Emil and the Detectives, is at the heart of the festival, with its city tale of hope, invention and dissent. But the writer and traveller Jay Griffiths criticises a Western risk-averse society for denying children the opportunity to roam free.
