Sergei Tretyakov, Russian Spy ‘Comrade J,’ Dead at 53

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.
Sergei was 53.
Helen asked those of us who were his friends to not immediately reveal his death until an autopsy could be performed under the supervision of the FBI. She was concerned that Sergei’s former colleagues in Russia’s SVR, which replaced the KGB as Russia’s foreign intelligence service, might attempt to use his unexpected death for propaganda purposes.
