The Masks of Death

The Masks of Death 1984 is a Sherlock Holmes film directed by Roy Ward Baker and starring Peter Cushing as the sleuth and John Mills as Doctor Watson.

Holmes, accompanied by Dr Watson, begins an investigation, but before he can make any real progress he is visited by the British Home Secretary and a German Diplomat, Count Udo von Felseck, who tell Holmes that a German envoy, on a secret mission to Britain, has disappeared from Felsecks house in Buckinghamshire. Unless Holmes can track him down, war between the two countries will become imminent. Holmes considers the possibility that the two matters are related and that someone is not telling him the truth.Executive producer Kevin Francis had previously attempted to raise funds for a new version of The Hound of the Baskervilles. Francis intended to cast Peter Cushing as Holmes, which would be Cushings third take on the Doyle tale after the 1959 Hammer production and the twopart production for the 1968 television series, and feature a stopmotion dog created by Ray Harryhausen. ........
