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.

From the best-selling author of Agent Zigzag, the thrilling true story of the greatest and most successful wartime deception ever attempted. One April morning in 1943, a sardine fisherman spotted the corpse of a British solder floating in the sea off the coast of Spain and set in train a course of events that would change the course of the Second World War.

The extraordinary story of British junior officers in the First World War, who led their men out of the trenches and faced a life expectancy of six weeks. During the Great War, many boys went straight from the classroom to the most dangerous job in the world - that of junior officer on the Western Front. Although desperately aware of how many of their predecessors had fallen before them, nearly all stepped forward, unflinchingly, to do their duty. The average life expectancy of a subaltern in the trenches was a mere six weeks.

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.

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.

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.

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.

Now leader of the UK himself, Boris Johnson explores what makes up the 'Churchill Factor' - the singular brilliance of one of the most important leaders of the 20th century. Taking on the myths and misconceptions along with the outsized reality, he portrays - with characteristic wit and passion - a man of multiple contradictions, contagious bravery, breath-taking eloquence, matchless strategizing and deep humanity. 

'If Hitler fails to invade or destroy Britain, he has lost the war,' Churchill said in the summer of 1940. He was right. The Battle of Britain was a crucial turning point in the history of the Second World War. Had Britain's defences collapsed, Hitler would have dominated all of Europe and been able to turn his full attention east to the Soviet Union. The German invasion of France and the Low Countries in May 1940 was unlike any the world had ever seen. It hit with a force and aggression that no-one could counter and in just a few short weeks, all in their way crumbled. 

SAS Ghost Patrol is the explosive true story of the day in 1942 when the SAS donned Nazi uniforms to perpetrate the most audacious and daring mission of the war. Beyond top secret, deniable in the extreme (and of course enjoying Churchill's enthusiastic blessing), this is one of the most remarkable stories of wartime lawlessness, eccentricity and raw courage in the face of impossible odds - a thoroughly British undertaking.

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.

Fascinating Footnotes From History details 100 of the quirkiest historical nuggets - eye-stretching stories that sound like fiction but are 100 percent fact. There is Hiroo Onoda, the lone Japanese soldier still fighting the Second World War in 1974; Agatha Christie, who mysteriously disappeared for 11 days in 1926; and Werner Franz, a cabin boy on the Hindenburg who lived to tell the tale when it was engulfed in flames in 1937.

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. 

In 1944, David Render was a 19-year-old second lieutenant fresh from Sandhurst when he was sent to France. Joining the Sherwood Rangers Yeomanry five days after the D-Day landings, the combat-hardened men he was sent to command did not expect him to last long. However, in the following weeks of ferocious fighting in which more than 90 per cent of his fellow tank commanders became casualties, his ability to emerge unscathed from countless combat engagements earned him the nickname of the 'Inevitable Mr Render'. 

It was the night of May 16th, 1943. Nineteen specially adapted Lancaster bombers take off from RAF Scampton in Lincolnshire, each with a huge cylindrical bomb strapped underneath them. Their mission: to destroy three dams deep within the German heartland, which provide the lifeblood to the Third Reich's war machine. What followed was an incredible race against time, which, despite numerous set-backs and against huge odds, became one of the most successful and game-changing raids of all time.
