What was the name of the book you were reading?

One of the better books I read was by David Kahn "The Codebreakers: The Story of Secret Writing"

I love cryptography and am always looking for good books on the subject.

The Code Book by Simon Singh is one of the best intros, I think.

It covers a lot more than Bletchley, but it gives Bletchley really good coverage and context.

A friend of mine built an enigma machine based on the description and wiring diagrams in the book: http://williamedwardscoder.tumblr.com/post/19946053957/enigm...
