I am besotted by all things Bletchley Park; there's nothing enigmatic about my warmth for the men and women who worked so hard for us and broke so many codes during WW2 to shorten it by maybe as much as three years. So another book on life there has just been devoured by YT and jolly good it was too. The extraordinary thing is that so many of the players - both large and small - have kept this very English story to themselves for so long.
If you've not been to the HQ - go and see a real piece of live history but close your eyes to some of the awfulness that surround the small site; just thank BT for its grubbiness and a gross piece of misunderstanding of part of its own history.
