On 3 May 1961, after a trial conducted largely in secret, a man named George Blake was sentenced to an unprecedented 42 years in jail. By his own confession he was a Soviet spy, but the reasons for such a severe punishment were never revealed. To the public, Blake was simply the greatest traitor of the Cold War. Yet his story touches not only the depths of treachery, but also the heights of heroism.

John Cairncross was among the most damaging spies of the 20th century. A member of the infamous Cambridge spy ring, he leaked highly sensitive documents from Bletchley Park, MI6, and the Treasury to the Soviet Union...Based on newly released archival materials, this biography will be the first to cover the life and espionage of this singularly important spy. 

A landmark collaboration between a thirty-year veteran of the CIA and a Pulitzer Prize-winning journalist, The Main Enemy is the inside story of the CIA-KGB spy wars, told through the actions of the men who fought them. Based on hundreds of interviews with operatives from both sides, The Main Enemy puts us inside the heads of CIA officers as they dodge surveillance and walk into violent ambushes in Moscow. This is the story of the generation of spies who came of age in the shadow of the Cuban missile crisis and rose to run the CIA and KGB in the last days of the Cold War.

David Rupert, a complete outsider with no connection to Ireland, rose to the very top of the Real IRA, all while working for the FBI and British intelligence. But the story is really about just how a bored, frustrated New York trucking manager becomes one of Britain’s most valued spies, brings down the entire IRA structure and makes $10 million in the process.    

GCHQ is the largest and most secretive intelligence organisation in the UK, and has existed for 100 years - but we still know next to nothing about it. In this ground-breaking book - the first and most definitive history of the organisation ever published - intelligence expert Richard Aldrich traces GCHQ’s development from a wartime code-breaking operation based in the Bedfordshire countryside into one of the world leading espionage organisations.

This is the incredible tale of Operation Fifth Column, a Second World War MI5 operation so secret that its existence was revealed by the National Archives for the first time only in 2014. Throughout the war and even for a couple of years afterwards, 'Agent Jack' - in reality, a bank clerk named Eric Roberts - acted as a Gestapo agent to whom hundreds of British-based Nazi sympathisers and informers passed their secrets, thinking that he was sending them back to Germany.

During the Cold War, world superpowers amassed nuclear arsenals containing the explosive power of one million Hiroshimas. The Soviet Union secretly plotted to create the "Dead Hand," a system designed to launch an automatic retaliatory nuclear strike on the United States, and developed a fearsome biological warfare machine. President Ronald Reagan, hoping to awe the Soviets into submission, pushed hard for the creation of space-based missile defenses.

This is one of the great untold stories of the 20th century. It is a firsthand account of a mission by an SAS soldier sent behind the Iron Curtain by MI6 to find someone who didn't necessarily want to be found and how, on a follow-up mission, he found himself manoeuvring against a mysterious KGB officer and a murder plot by Kremlin hardliners. If the plot had succeeded, it would have given the Russians the excuse they were looking for to roll out the tanks across East Germany, the Berlin Wall would not have fallen - and the map of Europe would look very different today.

A gripping tale of betrayal and counterbetrayal that tells the story of the most enigmatic member of the Cambridge spy ring - Donald Maclean. Donald Maclean was a star diplomat, an establishment insider and a keeper of some of the West's greatest secrets. He was also a Russian spy, driven by passionately held beliefs, whose betrayal and defection to Moscow reverberated for decades. 

'Trinity' was the codename for the test explosion of the atomic bomb in New Mexico on 16 July 1945.

The explosive first-hand account of America's secret history in Afghanistan. With the publication of Ghost Wars, Steve Coll became not only a Pulitzer Prize winner, but also the expert on the rise of the Taliban, the emergence of Bin Laden, and the secret efforts by CIA officers and their agents to capture or kill Bin Laden in Afghanistan after 1998.

Kevin Fulton was one of the British Army's most successful intelligence agents. Having been recruited to infiltrate the Provisional IRA at the height of the Troubles, he rose its ranks to an unprecedented level. Living and working undercover, he had no option other than to take part in heinous criminal activities, including the production of bombs which he knew would later kill. So highly was he valued by IRA leaders that he was promoted to serve in its infamous internal police - ironically, his job was now to root out and kill informers.

Wilhelm Canaris was appointed by Hitler to head the Abwehr (the German secret service) 18 months after the Nazis came to power. But Canaris turned against the Fuhrer and the Nazi regime, believing that Hitler would start a war Germany could not win. In 1938 he was involved in an attempted coup, undermined by British Prime Minister Neville Chamberlain. In 1940 he sabotaged the German plan to invade England, and fed General Franco vital information that helped him keep Spain out of the war.

London, 1963. The Beatles, Carnaby Street, mini skirts. But the new mood hasn't reached the drab and fearful corridors of MI5 and MI6. Many agents joined the secret service to fight the Nazis. Now they are locked in a Cold War against the Russians. And some of them are traitors. The service has been shaken to its core by the high-profile defections of Cambridge-educated spies Burgess, MacLean and now Philby. Appalled at such flagrant breaches of British security, the Americans are demanding a rigorous review.

Moscow in the late 1970s: one by one, CIA assets are disappearing. The perils of American arrogance, mixed with bureaucratic infighting, had left the country unspeakably vulnerable to ultra-sophisticated Russian electronic surveillance. The Spy in Moscow Station tells of a time when - much like today - Russian spycraft was proving itself far ahead of the best technology the US had to offer.
