Libby Purves meets wildlife presenter Steve Backshall; writer and academic Mary Chamberlain; pickpocket entertainer James Freedman and retailer Trevor Pickett. Mary Chamberlain is Emeritus professor of History at Oxford Brookes University. Her book, Fenwomen, was the first to be published by Virago Press 40 years ago and inspired Caryl Churchill's play Fen. When she was 23 Mary and her husband became involved with the anti-apartheid movement and were recruited as couriers for the ANC. The couple were part of a network of couriers around the world who, at great personal risk, smuggled anti-apartheid literature into South Africa. Her first novel, The Dressmaker of Dachau, is published by The Borough Press.
