Did you happen to catch "The Bletchley Circle" when it ran last year? If not, do try and find it...and even better, a second season is due for release soon. The Brits do these period dramas so very well.
I knew nothing of this, The Bletchley Circle; however I followed your link and it looks like great fun. I love Brit dramas, especially whodunits. Maybe Amazon has it on Prime. Otherwise, I don’t think it is on my cable package. Thanks for the heads up. I hope I can find the series somewhere to watch it.
