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.

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.

In this gripping narrative, Ben Macintyre tackles one of the most famous prison stories in history and makes it utterly his own. During World War II, the German army used the towering Colditz Castle to hold the most defiant Allied prisoners. For four years, these prisoners of the castle tested its walls and its guards with ingenious escape attempts that would become legend. But as Macintyre shows, the story of Colditz was about much more than escape.

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.

Britain's Special Air Service - or SAS - was the brainchild of David Stirling, a young, gadabout aristocrat whose aimlessness in early life belied a remarkable strategic mind. Where most of his colleagues looked at a battlefield map of World War II's African theater and saw a protracted struggle with Rommel's desert forces, Stirling saw an opportunity: Given a small number of elite, well-trained men, he could parachute behind enemy lines and sabotage their airplanes and war matériel.

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.

In We Don't Know Ourselves, Fintan O'Toole weaves his own experiences into Irish social, cultural, and economic change, showing how Ireland, in just one lifetime, has gone from a reactionary "backwater" to an almost totally open society - perhaps the most astonishing national transformation in modern history. O'Toole narrates the once unthinkable collapse of the all-powerful Catholic Church, brought down by scandal and by the activism of ordinary Irish. He relates the horrific violence of the Troubles in Northern Ireland, which led most Irish to reject violent nationalism.

In the spring of 1939, a top-secret organization was founded in London: Its purpose was to plot the destruction of Hitler's war machine through spectacular acts of sabotage. The guerrilla campaign that followed was every bit as extraordinary as the six men who directed it. One of them, Cecil Clarke, was a maverick engineer who had spent the 1930s inventing futuristic caravans. Now his talents were put to more devious use: He built the dirty bomb used to assassinate Hitler's favorite, Reinhard Heydrich.

While getting into his car on the evening of February 16, 1978, the chief of the CIA's Moscow station was handed an envelope by an unknown Russian. Its contents stunned the Americans: details of top-secret Soviet research and development in military technology that was totally unknown to the United States.

Spies is the history of the secret war that Russia and the West have been waging for a century. Espionage, sabotage, and subversion were the Kremlin’s means to equalize the imbalance of resources between the East and West before, during, and after the Cold War. There was nothing “unprecedented” about Russian meddling in the 2016 US presidential election. It was simply business as usual, new means used for old ends.
