Cianfarra reports his findings on the actions of The Vatican during the Second World War. Famously neutral during a time of intense conflict, Pope Pius XII's public appearances neglected to overtly support either side. In his foreword to the book, the author speculates whether The Vatican would have aligned itself with whichever side ultimately found itself successful after the war. A longtime foreign correspondent for the New York Times, Cianfarra spent seven years living in Rome, and based much of his writing on personal experience.
