Cracking the Nazi Code: The Untold Story of Canada's Greatest Spy by Jason Bell

adventurous challenging informative inspiring tense slow-paced

4.5

What a fascinating biography! I hadn’t heard of William Bell, but now want to learn more about him. 

The “code” in the title does not refer to the enigma machine or to other encryption codes.  It refers to being able to read the signals in the actions and words of the Nazis to understand their threat from back in 1919.
