Eddie Chapman was a charming criminal, a con man, and a philanderer. He was also one of the most remarkable double agents Britain has ever produced. Inside the traitor was a man of loyalty; inside the villain was a hero. The problem for Chapman, his spymasters, and his lovers was to know where one persona ended and the other began.

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.

On June 6, 1944, 150,000 Allied troops landed on the beaches of Normandy and suffered an astonishingly low rate of casualties. A stunning military achievement, it was also a masterpiece of trickery. Operation Fortitude, which protected and enabled the invasion, and the Double Cross system, which specialized in turning German spies into double agents, tricked the Nazis into believing that the Allied attacks would come in Calais and Norway rather than Normandy.

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.

As the American hostage crisis in Iran boiled into its seventh month in the spring of 1980, six heavily armed gunman barged into the Iranian embassy in London, taking twenty-six hostages. What followed over the next six days was an increasingly tense standoff, one that threatened at any moment to spill into a bloodbath.

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.

In Spies, Lies, and Algorithms, Amy Zegart separates fact from fiction as she offers an engaging and enlightening account of the past, present, and future of American espionage as it faces a revolution driven by digital technology. Drawing on decades of research and hundreds of interviews with intelligence officials, Zegart provides a history of US espionage, gives an overview of intelligence basics and life inside America's intelligence agencies, and explores the vexed issues of traitors, covert action, and congressional oversight.

Antonio Mendez and his future wife, Jonna, were CIA operatives working to spy on Moscow in the late 1970s, at one of the most dangerous moments in the Cold War. Soviets kept files on all foreigners, studied their patterns, tapped their phones, and even planted listening devices within the US embassy. In short, intelligence work was effectively impossible. The Soviet threat loomed larger than ever. The Moscow Rules tells the story of the intelligence breakthroughs that turned the odds in America's favor.

The Talmud says: “If someone comes to kill you, rise up and kill him first.” This instinct to take every measure, even the most aggressive, to defend the Jewish people is hardwired into Israel’s DNA. From the very beginning of its statehood in 1948, protecting the nation from harm has been the responsibility of its intelligence community and armed services, and there is one weapon in their vast arsenal that they have relied upon to thwart the most serious threats: Targeted assassinations have been used countless times, on enemies large and small....

The Dead Hand is the suspense-filled story of the people who sought to brake the speeding locomotive of the arms race, then rushed to secure the nuclear and biological weapons left behind by the collapse of the Soviet Union—a dangerous legacy that haunts us even today.The Cold War was an epoch of massive overkill.
