These are links to interesting Sherlock Holmes sites I have found.
The BBC have created the only known complete audio recording of the Canon. The writer of this was Bert Coules, a freelance writer. This is a link to the part of his site about these recordings. It contains cast lists, photographs and other details of these series of audio recordings staring Clive Merrison as Sherlock Holmes and Michael Williams as Dr. Watson. The complete series was broadcast on the BBC and is now available on audio cassette and CD.
