What surprised me most was just how successfully it was suppressed. Bletchley was a decaying set of mostly forgotten huts that did Enigma code breaking in the war and the surface of the story was barely scratched. I got especially interested in Bletchley and WW2 history right about the time the two or three significant books started coming out in the 80s. Gordon Welchman, another of the little known geniuses, moved to the US after the war to teach MIT's first computing course. He later worked on encryption for the US military. He wrote the Hut 6 Story in the 80s, the NSA didn't approve of his book, so he lost security clearance and was forbidden to talk about his own book or his involvement. There is a fascinating interview somewhere out there on the web, with some of his relatives, about him having a surveillance tail in his late seventies! https://en.wikipedia.org/wiki/Gordon_Welchman https://en.wikipedia.org/wiki/Gordon_Welchman
