The Secret Of Sherlock Holmes takes us on a journey into the mind of the great detective, probing his complex relationships with the two most significant people in his life. Holmes’s friendship with Dr Watson embraces both his driving ambition and an unspoken need for human contact. The archcriminal Professor Moriarty is, quite simply, his nemesis.

Following Holmes’s seemingly fatal encounter with Moriarty at the Reichenback Falls, Watson finds his loyalty tested to the very limit, while the great man is forced to confront his hidden demons and admit his deep-seated need for friendship.

Peter Egan and Philip Franks play Holmes and Watson, reprising the roles they played in The Hound Of The Baskervilles.
