Matthew Sweet and guests explore the art of the con.... If you've ever fallen for a scam, you'll be reassured by
Maria Konnikova's new book The Confidence Game, in which she explains why most of us are easy prey to con artists. Orson Welles was infamous early in his career for a radio broadcast of HG Wells' War of the Worlds which - it's said - caused genuine panic that aliens were invading earth. For Free Thinking Larushka Ivan-Zadeh discusses Welles's last film, F For Fake, which tells the tangled story of art forger Elmyr de Hory. And Gary Lachman and Kevin Jackson visit a new exhibition about Elizabethan alchemist, philosopher and mathematician John Dee - a mysterious figure who during his long career was sometimes a con-artist, and sometimes the conned.
