<P> The story was later adapted in 1986 as an episode of The Return of Sherlock Holmes starring Jeremy Brett . The episode is rather faithful to Doyle's story, except that Moran tries to shoot Holmes in Switzerland instead of dropping boulders on him, and it is Watson--not Holmes--that deduces the reason that Moran had for killing Ronald Adair . It was the first episode to feature Edward Hardwicke as Dr Watson, replacing David Burke who had played the role in the preceding episodes (Hardwicke reenacted a scene from The Final Problem in a flashback, consisting of Watson at the waterfall shouting to Holmes and reading his letter, which had been performed by Burke). </P> <P> (In the BBC Radio adaptation of "The Empty Room" starring Carlton Hobbs as Sherlock Holmes and Norman Shelley as Doctor Watson, Shelley refers to Ronald Adair as "Rupert" Adair, only to be corrected by Hobbs . It is a debate among Sherlock Holmes aficionados whether this was a mistake or an intentional humorous part of the script!) </P> <P> "The Empty House" was dramatised for BBC Radio 4 in 1993 by Bert Coules as part of his complete radio adaptation of the canon, starring Clive Merrison as Holmes and Michael Williams as Watson, and featuring Michael Pennington as Professor Moriarty, Frederick Treves as Colonel Moran, Donald Gee as Inspector Lestrade, and Peter Penry - Jones as Sir John . </P> <P> The 2009 radio play The Return of Sherlock Holmes, dramatised by M.J. Elliott combines "The Empty House" and "The Final Problem". </P>
