In a long, glowing review, the Washington Post calls Kertzer's findings 'truly shocking'

The review begins: " Of all the thorns in the side of the many apologists for Pope Pius XII, Brown University professor David I. Kertzer is probably the most formidable. Avoiding the strident tone of Garry Wills’s “Papal Sin” or John Cornwell’s aggressively titled “Hitler’s Pope,” Kertzer’s books about the papacy are models of calm, uncluttered prose, prodigious research, and the ability to appeal to both a scholarly and a general audience. In his new book, “The Pope at War: The Secret History of Pius XII, Mussolini, and Hitler,” Kertzer brings all of his usual detective and narrative skills to bear."
