Church Of Spies by Mark Riebling

The Pope's Secret War Against Hitler

A narrative history that examines how the Vatican during World War II built and ran a sophisticated intelligence and diplomatic network, using clergy, nuncios, and covert channels to gather information, influence events, and assist resistance and Allied efforts; the book contends that the papacy engaged in clandestine operations and moral compromises to counter Nazism while navigating complex political pressures and the controversy over its public silence and humanitarian actions.
