Radio Times are celebrating the best of TV, radio and books with a host of stars and TV insiders appearing on The Green at Hampton Court Palace for the Radio Times Festival. Every ticket includes access to gourmet food stalls, a shopping village, free events and screenings. One of the UK’s most respected crime-writers, Mark Billingham is a master of the police procedural. The author will be joined by longtime friend and journalist Mark Ellen to reflect on Billingham’s love of all things murderous. With Billingham’s latest novel already set for BBC dramatisation, it’ll also be a chance for the writer to discuss the pressures of adapting a story for the screen. Under 5 years go free, but must be seated on parents lap. Over 16s must purchase an adult ticket.
