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.

The new best-seller from the author of Zero Six Bravo. By 2007 Viktor Bout had become the world's foremost arms dealer. Known as the Merchant of Death, he was both public enemy number one to the global intelligence agencies and a ruthless criminal worth around $6 billion. For years Bout had eluded capture, meanwhile building up a labyrinthine network of airlines selling weapons to order to dictators, rebels, despots and terror groups worldwide.

In the Spring of 1940, as Britain reeled from defeats on all fronts and America seemed frozen in isolation, one fear united the British and American leaders like no other: the Nazis had stolen a march on the Allies towards building the atomic bomb. So began the hunt for Hitler's nuclear weapons - nothing else came close in terms of priorities. It was to be the most secret war of those wars fought amongst the shadows. The highest stakes. The greatest odds.

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.

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.

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. 

Peter Ratcliffe served in the SAS for 25 years. Blooded in Oman in the 1970s, he also saw action in Northern Ireland, in the Falklands War, and in the Gulf campaign. From his early days in the Paras to his time as Regimental Sergeant-Major in the Gulf, he has lived and fought by the motto 'who dares wins'. Eye of the Storm is his insider's account of that exceptional career. 

Michael Asher served in Northern Ireland with the Paras at the height of the IRA campaigns of the 1970s. He witnessed the result of using highly motivated assault troops in 'peacekeeping operations'. His depiction of the strengths and weaknesses of the British Army's elite airborne forces comes from his personal experience of what it was like for ordinary soldiers. From the Paras to the SAS and then service with the Special Patrol Group in Northern Ireland, Michael Asher's military odyssey eventually led him to leave the forces for a new life in the Sudanese desert. 

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. 

A captain in 29 Commando, Johnny Mercer served in the army for 12 years. On his third tour of Afghanistan, he was a joint fires controller, with the pressurized job of bringing down artillery and air strikes in close proximity to his own troops. Based in an area of Northern Helmand that was riddled with Taliban leaders, he walked into danger with every patrol, determined to protect them. Then, one morning, in brutal close-quarter combat, everything changed....

3 PARA was the first unit into Helmand in 2006. Sent on a peace mission, it became engaged in a level of combat that had not been experienced by the British Army since the end of the Korean War. Undermanned and suffering from equipment shortages, 3 PARA fought doggedly to win the break in battle. Numerous gallantry decorations were awarded, but they were not without cost. This is a dramatic, and often moving, insight into the leadership of soldiers at the sharp end of war.

In early summer 1982 - winter in the South Atlantic - Argentina's military junta invades the Falklands. Within days, a Royal Navy Task Force is assembled and dispatched. This is the story of D Squadron, 22 SAS, commanded by Cedric Delves. The relentless tempo of events defies belief. Raging seas, inhospitable glaciers, hurricane-force winds, helicopter crashes, raids behind enemy lines - the Squadron prevailed against them all, but the cost was high. 

Rob Driscoll, former sergeant with 42 Commando, Royal Marines, served tours in Iraq, Kuwait and Kosovo. A born leader of fighting men, with the medals to prove it, he also endured three tours in Afghanistan. The third of those will go down in history as one of the UK military's darkest hours, for it marked the first time a British serviceman has been tried for a murder on the battlefield since the Second World War.

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.

Born ‘a ragged-arsed kid from the backstreets of Glasgow’, McCallion joined the Paras to escape a miserable home life and find the family he longed for. After six tense tours in Ulster, McCallion gave up everything to move to South Africa in the hope of qualifying for the highly elite South African Special Forces. Having succeeded in joining the Recces, McCallion was involved in plots to assassinate Robert Mugabe and Joshua Nkomo.
