Negative Positive
Title: A must read for anyone remotely interested in codes!
Review: I have always been fascinated by codes and Singh has put together a comprehensive book on the history of codes. Having read many books on codes, Singh was still able to enthrall me with some historical stories that I had not come across. It's not just technical stuff, but is written with the novice in mind as well. But the book holds enough technical information to keep the enthusiast interested as well. The version I bought has a crypt contest in the back, which I enjoyed working on - I was only able to solve the first 3 or so puzzles, but it was a lot of fun.
