From ex-SAS Commander Tom Petch, this is the never-before-told story of how the world's preeminent Special Forces came into existence. Flashing between dramatic accounts from the frontlines and power negotiations in Westminster, it's an adventure that reaches from the trenches of the Western Front to piracy in the deserts of North Africa, to the final assault on Germany. Drawing on hidden archives and told with captivating drama, it focuses on two characters largely overlooked in the traditional narrative - Dudley Clarke the mastermind, and William Fraser the frontline operator. Without them there would never have been an SAS.
