The British really do period drama well. Often they choose strangely identifiable characters, which are played by highly competent actors. This show was much better than I expected. I really wondered how they were going to tie in code-breakers to a post-war world, and assumed it would be something to do with Russia. What a pleasant surprise to find these extraordinary women on the hunt for a serial killer. The science behind their quest was also extraordinary, and believe me, never suffers from the antiquated or mundane in terms of mind boggling genius in terms of their analytics. It's all very original indeed. The background is authentic 1950s and worth a look just for that. The social commentary was brilliant, though some may find it a little too extracurricular to the suspense of the main plot. The villain is good and evil, and I would have liked to have seen more of that, which is where my extra point disappeared. It would have given the story an extra kick to the suspense, which it needed, because a lot of the suspense was how husbands and other chaps would react to such aggressive role-breaking. It's a tiny criticism. This is truly a wonderful show. If you love excellent period piece BBC crime drama, then you are in for a treat when you discover The Bletchley Circle.
