"Hitler's Pope is the previously untold story of the man who was arguably the most dangerous churchman in modern history: Eugenio Pacelli, Pius XII, Pontiff from 1939 to 1958 and long controversial as the Pope who failed to speak out against Hitler's Final Solution. Here is the full story of how Pacelli in fact prompted events in the 1920s and '30s that helped sweep the Nazis to unhindered power."--BOOK JACKET.
