I am sorry to announce that my good friend, Sergei Tretyakov, the subject of my book, Comrade J: The Untold Secrets of Russia’s Master Spy in America After the End of the Cold War, died unexpectedly on June 13th in his home with his wife, Helen.
I was told that the autopsy shows no evidence of foul play, according to an FBI official who spoke to me off-the-record. Helen told me that her husband died from massive cardiac arrest. The Associated Press is reporting that a final autospy report will be released in late July.
