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.

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.

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. 

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.

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.

The history of the modern SAS is one of the great successes of postwar Britain. Since it was revived in 1950 to combat Communist insurgents, the Regiment has gone from strength to strength, fighting covert wars in Oman, Borneo, Northern Ireland, the Falklands, the Persian Gulf and beyond. In the process, it has become one of the most indispensable, and at times controversial, units in the British army.

The finest fighting force in the world. Escape. Evade. Survive. Repeat. Seven gripping tales of overcoming the impossible. Arguably the finest special forces troops of the Second World War, the SAS was the jewel in the British military crown. But the near-impossible nature of their heroic missions sometimes left them trapped behind enemy lines, the enemy closing and forced to endure the unendurable. But the unendurable is all in a day’s work for these magnificent seven. Incredible odds. Outstanding bravery. Real adventure.

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.

In the winter of 1941 an alien-seeming object was captured in a death-defying dash by an RAF reconnaissance pilot flying a lone unarmed Spitfire across the French coast. Balanced upon the cliffs near Le Havre was what appeared to be a giant convex dish, directed across the Channel at the war-torn British coastline. With Britain's cities being pounded by fearsome bombing raids, teams of experts studied the photograph worriedly.

In the bleak moments after defeat on mainland Europe in winter 1939, Winston Churchill knew that Britain had to strike back hard. So Britain's wartime leader called for the lightning development of a completely new kind of warfare, recruiting a band of eccentric free-thinking warriors to become the first 'deniable' secret operatives to strike behind enemy lines, offering these volunteers nothing but the potential for glory and all-but-certain death.

In the hard-fought winter of 1944, the Allies advanced northwards through Italy but stalled on the fearsome mountainous defences of the Gothic Line. Two men were parachuted in, in an effort to break the deadlock. Their mission: to penetrate deep into enemy territory and lay waste to the Germans' impregnable headquarters. At the 11th hour, mission commanders radioed for David 'The Mad Piper' Kilpatrick to be flown in, resplendent in his tartan kilt. They wanted this fearless war hero to lead the assault, piping 'Highland Laddie' as he went - so leaving an indelible British signature to deter Nazi reprisals.

The Nazi Hunters is the incredible, hitherto untold story of the most secret chapter in the SAS' history. Officially, the world's most elite special forces unit was dissolved at the end of the Second World War and not reactivated until the 1950s. Among their last actions was a disastrous commando raid into occupied France in 1944, which ended in the capture, torture and execution of 31 soldiers.

January 1991: IRAQ. Eight members of the SAS regiment embark upon a top-secret mission to infiltrate deep behind enemy lines. Under the command of Sergeant Andy McNab, they are to sever a vital underground communication link and to seek and destroy mobile Scud launchers. Their call sign: BRAVO TWO ZERO. Each laden with 15 stones of equipment, they tab 20km across the desert to reach their objective. But within days, their location is compromised. After a fierce fire fight, they are forced into evasive action. Four men are captured. Three die. Only one escapes.

Colditz - the dreaded POW camp was supposed to be impregnable. It was the German fortress from which there was no escape. It had been escape-proof in the 1914-18 war and was to be again in the Second World War, according to the Germans... This is the true story that has passed into legend: the story of the incredible courage and daredevil ingenuity of those who refused to admit defeat - those who burrowed, leapt and ran their way to freedom.

From its early beginnings in World War II, the Special Air Service (SAS) has won renown in some of the most dramatic, dangerous and controversial military special operations of the 20th century. It is a secretive and mysterious unit, whose operations and internal structures are hidden from the public eye. Now, one of its longest-serving veterans offers a glimpse into the shadowy world of the SAS. Rusty Firmin spent an incredible 15 years with 'The Regiment' and was a key figure in the assault of the Iranian Embassy in London in May 1980.
