Vatican Secret Diplomacy

My great high school friend has just released his latest book - Vatican Secret Diplomacy. My friend: Charles R. Gallagher, S.J. or Chaz to his old school friends has become an accomplished scholar. You can buy it an Amazon. I am half way through the book and is very interesting if you are a history buff or are interested in the role the catholic church played (or didn't play) during WWII and Nazism.
