More Bletchley Circle

The Bletchley Circle has maintained its very high standards.
Series 2 has the group of women, who had been code-breakers at Bletchley Park during the war, trying to prove the innocence of another Bletchley girl who has been accused of murder. The victim is a scientist played by Paul McGann.
That story deals with Cold War spying and experiments at Porton Down, while the second half of the series (only 4 episodes to a season, sadly) deals with Maltese gangsters trafficking girls into the country, via a little 'harmless' perfume smuggling. Spivs selling dodgy nylons were still around, as was rationing, in the early 1950s.

The beauty of the series is that there are four main characters who work together, so when Susan leaves, she is replaced by Alice, and by the time of the third season, set in San Francisco, there are only two members of the original team left, Millie and Jean.
They discover that a murderer in San Francisco is killing women in exactly the same way as one of their colleagues at Bletchley during the War was murdered, and travel there to see if they can bring him to justice. But they need some local knowledge, so first they have to track down an American code-breaker Jean was in touch with during the War, who they know only as Major Six.
The story takes place against the backdrop of the Fillmore district, where mainly black families are being forced out for re-development to take place. During the War, the area was home to a Japanese community, who were also forcibly removed.
And for the second part of the series, it all goes a bit Peyton Place, with intelligent women trapped in loveless marriages and meaningless lives in the suburbs, until one of them is killed in what seems to be a hit and run accident - or was it murder? (The only really happy marriage seems to be between Iris and her husband living in the Fillmore).

I'm looking forward to seeing Millie, Jean, Iris and Hailey in Part Two.
