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. 

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.

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.

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.

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.

From his cage in a putrid, overcrowded Indian jail, Paul Jordan reflects on a life lived on the edge. His childhood, marred by the loss of his father and brother, produces a young man hell-bent on being the best of the best - an ambition he achieves by being selected to join the elite SAS. The Easy Day Was Yesterday is fast paced, brutally honest, raw and laced with dark humour. The core of Paul Jordan's eventful life, it shows the ability of the human spirit to survive even in the direst adversity.

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.

The No. 1 Sunday Times bestselling modern classic: A Bravo Two Zero for the Second Gulf War. They were branded as cowards and accused of being the British Special Forces Squadron that ran away from the Iraqis. But nothing could be further from the truth. Ten years on, the story of these sixty men can finally be told. In March 2003 M Squadron - an SBS unit with SAS embeds - was sent 1,000 kilometres behind enemy lines on a true mission impossible, to take the surrender of the 100,000-strong Iraqi Army 5th Corps.

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.

Shortly after the outbreak of the Second World War, a country house called The Firs in Buckinghamshire was requisitioned by the War Office. Sentries were posted at the entrance gates, and barbed wire was strung around the perimeter fence. To local villagers it looked like a prison camp. But the truth was far more sinister. This rambling Edwardian mansion had become home to an eccentric band of scientists, inventors and bluestockings. Their task was to build devastating new weaponry that could be used against the Nazis.

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.

Throughout human history the art of warfare has evolved into many forms across numerous theatres, gradually becoming more sophisticated and strategised as the centuries have progressed. From the Spartans of ancient Greece with their code of valour fighting to the last man to the US Navy SEALs who operate using the latest technology of the 21st century. Across the vast array of military campaigns and battles one can see that the majority of organised armies have been comprised of enlisted men who would have their basic training. 

Former SAS soldier Big Phil Campion tells it like is in this brutally honest account of his insanely dangerous life as a private military operator. From playing chicken with a suicide bomber in backstreet Kabul to taking on pirates with his bare hands, this is true-life action-packed drama at its best. 

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.
