It takes in the exploits of spies naval officers & ordinary British seamen who risked & in some cases lost their lives snatching the vital Enigma codebooks from under the noses of Nazi officials & from sinking German ships & submarines. This book tells the whole Enigma story: its original invention & use by German forces & how it was the Poles who first cracked & passed on to the British
- the key to the German airforce Enigma. The more complicated German Navy Enigma appeared to them to be unbreakable.
