Washington D.C., Jun 23, 2016 / 03:06 am (CNA/EWTN News).- Pope Pius XII’s secret support for the attempted overthrow of Nazi dictator Adolf Hitler is the subject of a new book that draws on wartime documents and interviews with the American intelligence agent who wrote them.

“This book is the truth – as best I could establish it in a number of years of research – about the Pope’s secret operations in World War II,” historian Mark Riebling told CNA earlier this year. MORE
