Clive Merrison and Andrew Sachs star in seven original BBC Radio 4 full-cast adventures for Holmes and Watson.

How many times did Dr John Watson tantalise us with passing references to a mystery which his creator, Sir Arthur Conan Doyle, never wrote about in full? In these original adventures Bert Coules, the chief dramatist of BBC Radio 4’s celebrated Sherlock Holmes canon, has imaginatively fleshed out seven such unrecorded cases.

The Determined Client: Miss Addleton engages Holmes to save her father's good name.
The Striking Success of Miss Franny Blossom: Holmes investigates a respectable gambling club.
The Thirteen Watches: Bizarre events on an express train brings a railway baron to Baker Street.
The Ferrers Documents: A slum landlord and a missing witness figure in a dark tale of hatred and revenge.
The Remarkable Performance of Mr Frederick Merridew: A night at the music hall ends in tragedy.
The Eyes of Horus: A priceless Egyptian artefact vanishes from a locked casket in a locked vault.
The Marlbourne Point Mystery: Holmes and Watson discover death, treachery and betrayal on an isolated coastal headland.
