Martin Plimmer is a journalist and broadcaster and author of the fictionalised memoir King of the Castle. Once, while in the waiting room of a hospital after banging his head, Martin found a two-year-old magazine open at an article he had written on the subject of headaches. Brian King is an award-winning pioneer of radio fly-on-the-wall documentaries and producer of hundreds of BBC radio features, dramas and comedy programmes including, coincidentally, a Radio 4 series about coincidence, presented by Martin Plimmer. As well as Beyond Coincidence, he's the author of books about lying (The Lying Ape) and embarrassment (Walking in on Mum and Dad). When he's not making radio programmes or writing books, he can be found fighting slugs on his allotment, strumming his guitar or organising folk festivals.
