If you want to discover the captivating history of the Cambridge Five, then pay attention.... During the poverty-stricken years of the Great Depression, when Britain’s financial markets plummeted and the poor and wealthy alike doubted the economic systems in which they participated, the potential of one political ideal shone like no other: Communism. Young intellectuals from the country’s very best schools discussed the premise of labor-value versus wealth-value, and a great many of them became card-carrying members of the Communist Party in Britain.

Guy Burgess is the most important, complex and fascinating of 'The Cambridge Spies' - the group of British men recruited to pass intelligence to the Soviets during World War Two and the Cold War. Burgess' story takes us from his student days in 1930s Cambridge, where he was first approached by Soviet scouts, through his daring infiltration of the BBC and the British government to his final escape to Russia and lonely, tragic-comic exile there.

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.

D-Day, 6 June 1944, the turning point of the Second World War, was a victory of arms. But it was also a triumph for a different kind of operation: one of deceit. At the heart of the deception was the 'Double Cross System', a team of double agents whose bravery, treachery, greed and inspiration succeeded in convincing the Nazis that Calais and Norway, not Normandy, were the targets of the 150,000-strong Allied invasion force.

The Portland Spy Ring was one of the most infamous espionage cases from the Cold War. People the world over were shocked when its exposure revealed the shadowy world of deep cover KGB 'illegals' - spies operating under false identities stolen from the dead.

On a warm July evening in 1985, a middle-aged man stood on the pavement of a busy avenue in the heart of Moscow, holding a plastic carrier bag. In his grey suit and tie, he looked like any other Soviet citizen. The bag alone was mildly conspicuous, printed with the red logo of Safeway, the British supermarket. 

One December night in 1942, a Nazi parachutist landed in a Cambridgeshire field. His mission: to sabotage the British war effort. His name was Eddie Chapman, but he would shortly become MI5's Agent Zigzag. Dashing and suave, courageous and unpredictable, Chapman was by turns a traitor, a hero, a villain and a man of conscience. But, as his spymasters and many lovers often wondered, who was the real Eddie Chapman?

Kim Philby was the most notorious British defector and Soviet mole in history. Agent, double agent, traitor and enigma, he betrayed every secret of Allied operations to the Russians in the early years of the Cold War. Philby’s two closest friends in the intelligence world, Nicholas Elliott of MI6 and James Jesus Angleton, the CIA intelligence chief, thought they knew Philby better than anyone, and then discovered they had not known him at all.

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.

What pushed Blunt, Burgess, Cairncross, Maclean and Philby into Soviet hands? With access to recently released papers and other neglected documents, this sharp analysis of the intelligence world examines how and why these men and others betrayed their country and what this cost Britain and its allies.

Cambridge spy Guy Burgess was a supreme networker. He also set a gold standard for conflicts of interest, working variously for the BBC, MI5, MI6, the War Office, the Ministry of Information and the KGB. Yet Burgess was never challenged by Britain's spy catchers: his superiors were convinced he was too much of a liability to have been recruited by Moscow. Now, with a major new release of hundreds of files into the National Archives, Purvis and Hulbert reveal just how this charming establishment insider was able to fool everyone for so long.

April, 1943: A sardine fisherman spots the corpse of a British soldier floating in the sea off the coast of Spain and sets off a train of events that would change the course of the Second World War. Operation Mincemeat was the most successful wartime deception ever attempted, and the strangest. This is the true story of the most extraordinary deception ever planned by Churchill’s spies: an outrageous lie that travelled from a Whitehall basement all the way to Hitler’s desk.

Oleg Gordievsky was the highest ranking KGB officer ever to work for Britain. For 11 years, he acted as a secret agent, reporting to the British Secret Intelligence Service while continuing to work as a KGB officer. He gave such a clear insight into the mind and methods of the KGB and the whole system of Soviet government that he has been credited with doing more than any other individual in the West to accelerate the collapse of Communism. 

Magnus Pym, counsellor at the British Embassy in Vienna, has suddenly vanished, believed defected. The chase is on for a missing husband, a devoted father, and a life-time secret agent. Pym's life, it is revealed, is entirely made up of secrets. The race is on to find the perfect 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.
