Second World War code-breaking turned on its head - the aces were German and the British were too weak for words. Everyone knows the story of Enigma and code-breaking in the Second World War. Ace code-breakers from the previous war form the nucleus of a secret operation which achieves the impossible: obtaining war-winning intelligence from the enemy's secret codes.
