"The story of D-Day has been told from many points of view, but never before from the perspectives of the key individuals in the Double Cross system. These include its director (a brilliant, urbane intelligence officer), a colorful assortment of MI5 handlers (as well as their counterparts in Nazi intelligence), and the five spies who formed Double Cross's nucleus: a dashing Serbian playboy, a Polish fighter pilot, a bisexual Peruvian party girl, a deeply eccentric Spaniard with a diploma in chicken farming, and a volatile Frenchwoman whose obsessive love for her pet dog very nearly wrecked the entire plan. The D-Day spies were, without question, one of the oddest military units ever assembled, and their success depended on the delicate, dubious relationship between spy and spymaster, both German and British. Their enterprise was saved from catastrophe by a shadowy sixth spy whose heroic sacrifice is revealed here for the first time."--Publisher description.
