Summary:
Tells the story of one of the most dangerous war-time code-breaking efforts ever. As Hitler marched his troops across conquered lands and deadly "wolfpacks" of German U-Boats prowled the open seas, victory-or defeat-for the Allies hinged on their desperate attempts to crack the code. When a group of Allied spies and codebreakers cracked the Nazis's infamous cypher, it allowed them to read secret military messages and turn the tide of World War II.
