"The Adventure of Wisteria Lodge" was a rather lengthy, two=part story that was published as part of the collection of Sherlock Holmes stories collected under the title His Last Bow. The Granada TV adaptation is fairly faithful to its source material, despite having been simplified and shortened, in order to provide a bit more action and to fit into the 52-minute framework of a single episode. Jeremy Brett and Edward Hardwicke are both in good form as Holmes and Watson. (Unlike a couple other episodes during this season of the series, Brett doesn't seem to display much of the effect of the medication he was taking for his bipolar disorder.)
As the plot displays very little of Holmes's usual deductive prowess, most of the value of the episode for the viewer is the interplay between Holmes and the unusually competent Inspector Baynes, portrayed with excellent comic timing by British character actor, Freddie Jones. Holmes often seems both entertained and impressed by Baynes, and Baynes appears to respect Holmes, while also competing with him in a rather congenial fashion. So although I found the plot to be just a bit confusing (much like the original story), the banter between Holmes and Baynes is pretty entertaining.
A great improvement on the original material is the removal of much of the material from the story that tends to reflect the racism of Doyle's time: all of the "voodoo" plot line is removed, and other than a couple uses of the term "mulatto," most of the racist element is considerably toned town. Those elements, while reflecting Doyle's rather typical point of view for England in the Victorian age, add little to the plot, so I found the changes to be quite appropriate for our modern sensibilities.
Overall, while it was hardly one of my favorite episodes, it was enjoyable enough to watch, and for this viewer, at least, was a bit of an improvement on its source material. A decent, if somewhat inconsequential, installment in the Granada series. You may watch the episode below...
