Crime writer Bernard O’Keeffe talks about the DI Garibaldi series and, in particular, Every Trick in the Book , in which a murder victim is discovered in the very heart of leafy Barnes. When the victim turns out to be a local crime writer, O'Keeffe's country-music-loving detective needs all his skill to unravel the eerie similarities between the writer's murder and the murder depicted in his novel. Why are both the writer and the victim found dead in Barnes Pond only hours after giving a talk at the Barnes Book Festival? Ticket only is £12.
