The “explosive” (The New York Times) bestseller that  “redefined the history of the twentieth century” (The Washington Post ) 

This shocking book was the first account to tell the whole truth about Pope Pius XII's actions during World War II, and it remains the definitive account of that era. It sparked a firestorm of controversy both inside and outside the Catholic Church. Award-winning journalist John Cornwell has also included in this seminal work of history an introduction that both answers his critics and reaffirms his overall thesis that Pius XII fatally weakened the Catholic Church with his endorsement of Hitler—and sealed the fate of the Jews in Europe.
