A rich, atmospheric WWII thriller from the award-winning author of Moskva and Nightfall Berlin.

An unlikely spy.

July, 1940. As Britain braces itself for invasion, ex-Tommy and safecracker Bill O'Hagan is glad to have escaped the battlefield. But when a job goes wrong, he finds himself forced to serve his country once more. 

A former king.

Spurned by his government and fearing for his life, the Duke of Windsor flees to Portugal with the woman for whom he abdicated the throne, Wallis Simpson. As a web of Nazi trickery threatens to ensnare him, his fate and the fate of Britain rest on one man. 

The fate of a nation in their hands.

Dropped on an occupied Channel Island without backup, Bill must crack an enemy safe and get its contents to safety. Failure will devastate any hope Britain has of winning the war.

But with the layers of deception and intrigue drawing ever more tightly around them, Bill and the Duke both learn they aren't the only players in this game. And Berlin - which has the Duke in its own sights - is plotting its greatest move yet.... 

Jack Grimwood matches Robert Harris, Joseph Kanon, Ken Follett and John le Carré thrill for thrill in this breathtaking WWII story of atmospheric suspense, daring espionage and political intrigue, set in the tense depths of Britain's darkest hour.
