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.

D-Day, 6 June 1944 was a victory of arms. But it was also a triumph for a different kind of operation: one of deceit, aimed at convincing the Nazis that Calais and Norway, not Normandy, were the targets of the invasion force. The deception involved every branch of Allied wartime intelligence. But at its heart was the “Double Cross System”, a team of double agents controlled by the secret Twenty Committee.

Eddie Chapman: rogue, criminal, confidence trickster, hero to both sides and betrayer of all. At the start of the Second World War, Chapman was recruited by the German Secret Service. He was a highly prized Nazi agent. He was also a secret spy for Britain, alias Agent Zigzag.

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. 

In the summer of 1941, at the height of the war in the Western Desert, a bored and eccentric young officer, David Stirling, came up with a plan that was imaginative, radical and entirely against the rules: a small undercover unit that would wreak havoc behind enemy lines. Despite intense opposition, Winston Churchill personally gave Stirling permission to recruit the most ruthless soldiers he could find. So began the most celebrated and mysterious military organisation in the world: the SAS.

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. 

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.

You know about MI5. You know about MI6. Now uncover the story behind Britain’s most secretive intelligence agency in the first-ever authorised history of GCHQ.

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.

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.

In the boot were six homemade pipe bombs, all linked to detonate at the same time from a single call on a brand-new pay-as-you-go phone found on the target. Special Branch also found Chinese Type 56 assault rifles with eight full magazines of ammunition. His target was a local school. He planned to attack two coaches of teenagers returning home after a school trip to France. Approximately 60 children, their accompanying teachers and their waiting parents. He was going to kill them all.

In Putin's People, former Moscow correspondent and investigative journalist Catherine Belton tells the untold story of the rise of Vladimir Putin and the small group of KGB men surrounding him. Delving deep into the workings of Putin's Kremlin, Belton accesses key inside players to reveal how Putin replaced the free-wheeling tycoons of the Yeltsin era with a new generation of loyal oligarchs who in turn subverted their country's economy and legal system and expanded its influence in the West.

This riveting chronicle of submarine warfare is the first to cover all the major submarine campaigns of the war, describing, in detail, the operations of the British, American, Japanese, Italian, and German submarine and anti-submarine forces.

But with the growing threat from Moscow Centre, the office has one more job for him. Nat is to take over The Haven, a defunct substation of London General with a rag-tag band of spies. The only bright light on the team is young Florence, who has her eye on Russia Department and a Ukrainian oligarch with a finger in the Russia pie.  

In the Australia of the 1960s, '70s and '80s, armed robbers were the top of the criminal food chain. Their dash and violence were celebrated, and men like Ray Denning and Russell 'Mad Dog' Cox were household names long before Underbelly established Melbourne's gangland thugs as celebrities. Both were handsome, charismatic bandits who refused to bow to authority. Both were classified as 'intractable' in prison, and both escaped. Cox was the only man to escape from Katingal, Australia's only 'escape-proof' jail. Soon after he broke out, he tried to break in again and rescue his mates.
