The landmark documentary MIDSOMER MURDERS - 25 YEARS OF MAYHEM celebrates the 25-year legacy of one of Britain's best-loved and most enduring crime dramas. New interviews with key cast members, including Neil Dudgeon, John Nettles, Jane Wymark, and Jason Hughes, reveal how the series came to life from the pages of Caroline Graham's Chief Inspector Barnaby books, beginning with the first episode, "The Killings at Badger's Drift," in 1997.
