Mr. Krupp has compiled thousands of documents in his book, which proves Pope Pius XII was an unsung hero of World War II. Pope Pius XII secretly hid, fed and provided false documents to hundreds of thousands of Jews fleeing Hitler and his murderous henchmen according to the documents in this book. In all of the books out there against Pope Pius XII, not one has any documentation at all. Read for yourself. Even the biggest doubter will change his mind.
