When the Cold War ended, the spying that marked the era did not. An incredible true story from the Pulitzer Prize-nominated New York Times bestselling author of Crazy . Between 1995 and 2000, "Comrade J" was the go-to man for SVR (the successor to the KGB) intelligence in New York City, overseeing all covert operations against the U.S. and its allies in the United Nations. He personally handled every intelligence officer in New York. He knew the names of foreign diplomats spying for Russia. He was the man who kept the secrets. But there was one more secret he was keeping. For three years, "Comrade J" was working for U.S. intelligence, stealing secrets from the Russian Mission he was supposed to be serving. Since he defected, his role as a spy for the U.S. was kept under wraps-until now. This is the gripping, untold story of Sergei Tretyakov, more commonly known as "Comrade J."
