Just as "The Illustrious Client" was about a man who preyed on women, this episode is about a woman who preyed on men. It's feels like a melodrama rather than a mystery. Watching it is a bit depressing and it contains no real twists or turns. However, it does have some redeemable qualities. While this was not one of Conan Doyle's better tales, it is faithful to the original story so purists won't be upset. The performances are good, Jeremy Brett and Edward Hardwicke are excellent as usual and Claudine Auger is strong as Isadore Klein. The art and set decoration are still superb (just look at that lavish ball scene). Still, this production is overwrought and thus one of weaker adaptations in the series.
