This was taken from a mini-series, wouldn't have watched had I known that. Holmes goes to the dark continent under orders from Her Majesty's Government to guard a very valuable stone which unfortunately comes up missing. Holmes and Watson must unravel this puzzling mystery while avoiding the actions on the local constabulary headed by an unbelievably pompous, inept jackass of an inspector. Lee played the part of the aging sleuth well in a bit of a different outing for the Brit crime buster. Too many gaps in the story and an ending which even Holmes couldn't figure out. Bypass unless you can see the whole production I would say.
