An interesting adaptation here from the Hammer studio. As far as I know apart from some deviations in minor details this is fairly close to the original story.
Benefitting form Terrance Fishers usual lavish direction the film is eminently watchable and Cushings version of Holmes is a joy to behold however the movie does seem to have lost a lost of the essential spookiness of the source material and the threat never feels at all supernatural. A shame really as this is an otherwise solid movie.
Worth a watch.
