Evans was close friends with the late Herbert Romerstein, who wrote the well-researched book The Venona Secrets. The Venona decrypts were encrypted communications going back and forth between Moscow and their Soviet agents operating within the United States. They reveal a breathtaking level of infiltration at the highest levels within the U.S. government, going all the way up to the White House. Evans and Romerstein collaborated on the book Stalin’s Secret Agents: The Subversion of Roosevelt’s Government, an appropriate followup to Blacklisted by History.
