The story is a little on the thin side, if decidedly chilling at the climax. But the pleasure of watching a first-rate assortment of mature actors go through their paces makes this a show worth watching again and again. Peter Cushing's Holmes is severe, ascetic and all business, John Mills' Watson cheerful and worth having in a tight spot, and Anne Baxter's Irene Adler a genuinely charming and intelligent lady.
