This is the true story of a decade-long series of Nazi espionage plots in Britain, Europe and the United States.
It shows how a Nazi spy's letter, posted in New York and intercepted in Scotland, broke spy rings across Europe and North America.
And it reveals, for the first time, how that letter marked the genesis of an intelligence and security alliance that today includes the United States, the UK, Canada, Australia and New Zealand.
'Fascinating, gripping and expertly researched... an extraordinary true tale of espionage told with all the drama and panache of a spy thriller' – Michael Smith, bestselling author of The Secrets of Station X.
