Jeremy Brett is simply the best Holmes ever, narrowly edging out the great Basil Rathbone of course, and this is probably the best adaptation of a Conon-Doyle short story.A length adaptation includes some new plot strands that fit in well to the surrounding drama and heightens the hatred one feels for Milverton.Excellent performances all round, especially from Robert Hardy, and both Brett and Hardwick fully rounded and comfortable in their roles makes this a superb piece of drama.
