In 1991 the Soviet Union collapsed, the cold war ended, and a new world order began. We thought everything had changed. But one thing never changed: the spies.

From 1995 to 2000, a man known as "Comrade J" was the highest-ranking operative in the SVR - the successor agency to the KGB - in the United States. He directed all Russian spy action in New York City and personally oversaw every covert operation against the United States and its allies in the United Nations. He recruited spies, planted agents, penetrated security, manipulated intelligence, and influenced American policy - all under the direct leadership of Boris Yeltsin and then Vladimir Putin. He was a legend in the SVR, the man who kept the secrets.

Then, in 2000, he defected - and it turned out he had one more secret. For the previous two years, he had also been a double agent for the FBI.

He has never granted a public interview. The FBI and CIA have refused to answer all media questions about him. He has remained in hiding. He has never revealed his secrets. Until now.

Comrade J, written by the best-selling author of Family of Spies and The Hot House, is his story, a direct account of what he did in the United States after we all assumed the spying was over - and of what Putin and Russia continue to do today. The revelations are stunning. It is also the story of growing up in a family of agents dating back to the revolution; of how Russia molded him into one of its most high-flying operatives; of the day-to-day perils of living a double, then triple, life; and finally, of how his growing disquiet with the corruption and ambitions of the "new Russia" led him to take the most perilous step of all.
