This book hits me on several levels. I have always been interested in WWII espionage for some reason and I’m a bookseller. So, when I found a book about WWII codes and cryptoanalysis by the son of a famous antiquarian bookseller, I just had to read it.

It was entertaining and instructive. I feel that I know a great deal more about codes and coding after reading this book.

It is well written and I would recommend it to anyone who is looking for information about codes, coding, or the SOE in WWII.
