Between Hitler and Churchill exposes an unknown facet in the World War II history: the attempt of a senior official in the Polish government-in-exile to collude with the Third Reich and a successful British intelligence operation which thwarted this move in its infancy. This surprising and fascinating event is described through the personal stories of its two main protagonists, Polish Jews. One of them mediated the said Polish-German contacts, while the other assisted the British in capturing the mediator in the Middle East and murdering him there without trial. Although it reads like a historical thriller, the book is based on British, Polish, German and Russian diplomatic and intelligence reports, many of which are revealed and analyzed here for the first time.
