Berlin was in ruins when Soviet forces fought their way towards the Reichstag in the spring of 1945. Streets were choked with rubble, power supplies severed and the population close to starvation. The arrival of the Soviet army heralded yet greater terrors: the city's civilians were to suffer rape, looting and horrific violence. Worse still, they faced a future with neither certainty nor hope.

In the quiet Cotswolds village of Great Rollright in 1944, a thin and unusually elegant housewife emerged from her cottage to go on her usual bike ride. A devoted mother of three, attentive wife and friendly neighbour, Sonya Burton seemed to epitomise rural British domesticity. However, rather than pedalling towards the shops with her ration book, Sonya was heading for the Oxfordshire countryside to gather scientific secrets from a nuclear physicist. Secrets that would enable the Soviet Union to build the atomic bomb.

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. 

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.

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. 

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.

Spring 1958: a mysterious individual believed to be high up in the Polish secret service began passing Soviet secrets to the West. His name was Michal Goleniewski, and he remains one of the most important yet least known and most misunderstood spies of the Cold War. Even his death is shrouded in mystery and he has been written out of the history of Cold War espionage - until now. 

Richard Sorge was a man with two homelands. Born of a German father and a Russian mother in Baku in 1895, he moved in a world of shifting alliances and infinite possibility. A member of the angry and deluded generation who found new, radical faiths after their experiences on the battlefields of the First World War, Sorge became a fanatical communist - and the Soviet Union’s most formidable spy.

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. 

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.

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.

'Trinity' was the codename for the test explosion of the atomic bomb in New Mexico on 16 July 1945. This exceptional book - Trinity - tells the story of the bomb's metaphorical father, Rudolf Peierls; his intellectual son, the atomic spy, Klaus Fuchs; and the ghosts of the security services in Britain, the USA and USSR.

When Browder’s young Russian lawyer, Sergei Magnitsky, was beaten to death in a Moscow jail in 2009, Browder cast aside his business career and made it his life’s mission to pursue justice for Sergei. One of the first steps of that mission was to uncover who had killed Sergei and profited from the $230 million corruption scheme that he had exposed. As Browder and his team tracked the money that flowed out of Russia—through the Baltics and Cyprus and on to Western Europe and the Americas—they discovered that Vladimir Putin himself was one of the beneficiaries of the crime. 

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?
