What to read after Germany's Underground?

Germany's Underground, first published in 1947, is the classic inside look at German resistance movements attempting to overthrow Adolph Hitler and the Nazi regime. Author Allen Dulles, younger brother of John Foster Dulles, was the OSS chief of station in Bern Switzerland, and had extensive personal contacts with members of the German underground. Following the war's end, he was stationed in Germany, providing him with access to captured secret Nazi documents. He was also able to interview the handful of surviving men and women involved in attempts to overthrow the Nazis or assassinate Hitler. Germany's Underground is a fascinating look at the individuals involved in the German resistance as well as an examination of morality and ethics in the midst of a brutal police state. Allen Dulles was appointed director of the U.S. CIA in 1953, a position he held until 1961. Dulles, born in 1893, passed away in 1969.
