Breaking the German Enigma codes was not only about brilliant mathematicians and professors at Bletchley Park. There is another aspect of the story which it is only now possible to tell. It takes in the exploits of spies, naval officers and ordinary British seamen who risked, and in some cases lost, their lives snatching the vital Enigma codebooks from under the noses of Nazi officials and from sinking German ships and submarines. This book tells the whole Enigma story.

For almost four desperate years between 1939 and 1943, British and American navies fought a savage, losing battle against German submarine wolf packs. The Allies might never have turned the tide of that historic battle without an intelligence coup. The race to break the German U-boat codes is one of the last great untold stories of World War II.

According to Winston Churchill, Alan Turing made the single biggest contribution to the Allied victory over Nazi Germany with his code-breaking machine. The world is also indebted to Turing's genius for the modern computer. It was clear that Turing had a remarkable mind from an early age. He taught himself to read in just three weeks. At his first school, the headmistress said, "I have had clever and hardworking boys, but Alan has genius."

Fort Knox is one of those rare phrases that has escaped its physical boundaries and entered everyday language. It is spoken casually, often without thought, as a shorthand for something impenetrable, something absolute. To say that something is “as safe as Fort Knox” is to suggest that it is beyond reach, beyond threat, beyond question. Yet the reality behind this familiar expression is far more grounded, far more human, and far more structured than the myth allows. Fort Knox is not an ancient fortress shaped by centuries of siege and legend.

In less than six hours in August 1942, nearly 1,000 British, Canadian, and American commandos died in the French port of Dieppe in an operation that, for decades, seemed to have no real purpose. Canadian historian David O’Keefe uses hitherto classified intelligence archives to prove that this catastrophic and apparently futile raid was, in fact, a mission set up by Ian Fleming of British Naval Intelligence as part of a “pinch” policy designed to capture material relating to the four-rotor Enigma Machine.

Alan Mathison Turing. Mathematician, philosopher, codebreaker, a founder of computer science, and the father of Artificial Intelligence, Turing was one of the most original thinkers of the last century - and the man whose work helped create the computer-driven world we now inhabit. But he was also an enigmatic figure, deeply reticent yet also strikingly naive. Turing's openness about his homosexuality at a time when it was an imprisonable offense ultimately led to his untimely death at the age of only 41.

In the winter of 1941 an alien-seeming object was captured in a death-defying dash by an RAF reconnaissance pilot flying a lone unarmed Spitfire across the French coast. Balanced upon the cliffs near Le Havre was what appeared to be a giant convex dish, directed across the Channel at the war-torn British coastline. With Britain's cities being pounded by fearsome bombing raids, teams of experts studied the photograph worriedly.

Hitler's U-boats rule the North Atlantic and threaten to eliminate the Allied supply lines through meticulously coordinated attacks using Germany's secret weapon: the Enigma. Desperate to turn the tide of the war, British scientists at Bletchley Park work tirelessly to break the codes. But there is a problem. They need the German ciphers and a working Enigma machine.
