The Further Adventures of Sherlock Holmes is a series of radio dramas based on Arthur Conan Doyle's detective Sherlock Holmes. Written by Bert Coules as a pastiche of Doyle's work, the series was broadcast on BBC Radio 4 in 2002, 2004, 2008–2009 and 2010. There are sixteen episodes, all of them produced and directed by Patrick Rayner of BBC Scotland. Clive Merrison stars as Holmes, having portrayed the detective in a 1989–1998 BBC radio series of dramatisations of every Sherlock Holmes story by Doyle (the first actor to do so). Andrew Sachs appears as Dr. Watson, replacing Michael Williams after Williams died following the Radio 4 run of Sherlock Holmes adaptations. Each of the stories is based on a throwaway reference from an actual Doyle short story or novel. The first two series are repeated regularly on BBC Radio 4 Extra.

The 2010 episode "The Marlbourne Point Mystery: Part Two" brings to eighty the number of episodes in which Clive Merrison has played Sherlock Holmes on BBC Radio 4.
