The Memoirs of Sherlock Holmes: The Golden Pince-Nez

 "May I shake your hand, Sir?"

"What? If you must."

Now that's more like it. This is the first solid episode in ages from the once-dependable Granada Sherlock Holmes. After a few episodes that were, essentially, not whodunits, at last we get an adaptation of a solid Conan Doyle murder mystery with a genuinely surprising and unpredictable twist. This may not be a highlight of the series, but it's an enormous relief to encounter an episode like this. Let's hope it represents an overdue return to form for the final stretch.

This is a broadly faithful adaptation, with the changes making sense with the casting- and the cast is truly excellent. The episode is notably missing Edward Hardwicke as Watson, of course, but it just about works having the superb but noticeably older Charles Gray return as Mycroft. The interplay between the two brothers is fascinating- Holmes archly notes that it os "ironic" that their late father left his magnifying glass to the sedentary Mycroft, although there's just about enough sleight of hand to excuse his not being so sedentary here.

There's a nice little red herring with Suffragettes too, and some wry social commentary on Edwardian attitudes to female suffrage, which Mycrofy is very much seen to share. The opening and concluding scenes with nihilists in Russia in the 1880s are well done, too- shades of the assassination of Tsar Alexander II.

Please let this not be the last good episode...
