If anyone could be considered a Russian counterpart to the infamous British double-agent Kim Philby, it was Oleg Gordievsky. The son of two KGB agents and the product of the best Soviet institutions, the savvy, sophisticated Gordievsky grew to see his nation's communism as both criminal and philistine. He took his first posting for Russian intelligence in 1968 and eventually became the Soviet Union's top man in London, but from 1973 on he was secretly working for MI6.

This revealing memoir from a 34-year veteran of the CIA who worked as a case officer and recruiter of foreign agents before and after 9/11 provides an invaluable perspective on the state of modern spy craft, how the CIA has developed, and how it must continue to evolve.

Enrique Prado found himself in his first firefight at age seven. The son of a middle-class Cuban family caught in the midst of the Castro Revolution, his family fled their war-torn home for the hope of a better life in America. Fifty years later, the Cuban refugee retired from the Central Intelligence Agency as the CIA equivalent of a two-star general. Black Ops is the story of Ric’s legendary career that spanned two eras, the Cold War and the Age of Terrorism.

Who was Kim Philby? Those closest to him—like his fellow MI6 officer and best friend since childhood, Nicholas Elliot, and the CIA’s head of counterintelligence, James Jesus Angleton—knew him as a loyal confidant and an unshakeable patriot. Philby was a brilliant and charming man who rose to head Britain’s counterintelligence against the Soviet Union. Together with Elliott and Angleton he stood on the front lines of the Cold War, holding Communism at bay. But he was secretly betraying them both: He was working for the Russians the entire time.

In 1942, in a quiet village in the leafy English Cotswolds, a thin, elegant woman lived in a small cottage with her three children and her husband, who worked as a machinist nearby. Ursula Burton was friendly but reserved, and spoke English with a slight foreign accent. By all accounts, she seemed to be living a simple, unassuming life. Her neighbors in the village knew little about her. They didn’t know that she was a high-ranking Soviet intelligence officer. They didn’t know that her husband was also a spy, or that she was running powerful agents across Europe.
