I love Bletchley Park - I wrote a 5000 word essay on it in my last year of school. Just the thought of this top secret base, hidden in plain sight, filled with the best and most eccentric intellectuals of the day working together for the war effort appeals to the maths geek and the patriot in me. That spirit was encapsulated perfectly here - although the book doesn't touch much on the actual workings of the mathematics that was being done, it is such a brilliant insight into the atmosphere and day-to-day life at Bletchley. Needless to say, after reading this I want to be there even more!
