Profoundly interesting in terms of what was achieved and how but the tone of the book is pompous and sexist. It makes it sound like Bletchley Park was a secret university for posh people who also put on plays and performed opera. I feel the emphasis should have remained on the technical prowess and war time effect on strategy at that time. Don't bother with the book: go to the museum. It will fill you with wonder and respect for what happened there!
