In this revelatory chronicle of World War II, Laurence Rees documents the dramatic and secret deals that helped make the war possible and prompted some of the most crucial decisions made during the conflict.

Drawing on material available only since the opening of archives in Eastern Europe and Russia, as well as amazing new testimony from nearly a hundred separate witnesses from the period-Rees reexamines the key choices made by Stalin, Churchill and Roosevelt during the war, and presents, in a compelling and fresh way, the reasons why the people of Poland, the Baltic states, and other European countries simply swapped the rule of one tyrant for another. Surprising, incisive, and endlessly intriguing, World War II Behind Closed Doors will change the way we think about the Second World War.
