I stumbled acorss this new series purley by accident and I am so glad I did. It's called the Bletchley Circle and is set in 1952. It's a mini series drama. These four ladies used to be codebreakers for during the war and have since returned to their normal lives. However a series of murders in their area show a pattern which leads them to start investigating themselves.
You can still see the first episode on Iview ( I think it's there for another week ) and then it shows on the ABC on friday night 9.20pm.
I'm loving it can't wait for the next episode!
