Ultimate soldier. Ultimate mission. But can the SAS break in to a Colombian island prison and snatch an Argentine killer? 1996: a terminally ill father desperately seeks answers to what happened to his son, missing for twenty years. He has the names of two Argentine men - one in Mexico City, the other imprisoned on the Colombian island of Providencia - but no one to ask the questions. A missing girl's family have given her up for dead when they stumble upon a Miami newspaper story mentioning two of her friends. One has just died; the other, half-deranged, tells a garbled story of sexual slavery on a Caribbean island which sounds suspiciously like Providencia. MI6 and the British government are certain that a huge drug-trafficking empire is being run from the prison, and know that some of the profits are being funnelled by its Argentine 'guest' into financing a mercenary invasion of the Falklands. Ignored by the Colombian authorities and mysteriously obstructed by their American allies, the British have no choice but to send in their own elite force - the SAS.

Ultimate soldier. Ultimate mission. But will the SAS locate their target and make it out of the jungle alive? In the Central American republic of Guatemala, government-sponsored torture and mass murder has reduced the Mayan Indian population to a despairing acquiescence. After five hundred years of struggle it seems as if the conqueror's peace can at last be proclaimed in the capital. Then a guerrilla leader who the authorities have long believed dead springs mysteriously back to life. No loyal Guatemalan can identify him, and the government is compelled to seek help elsewhere, from one of the two SAS soldiers who helped mediate a hostage crisis with the guerrilla almost fifteen years earlier. To the government in Whitehall it appears a straightforward enough exercise, but for the soldier and his comrades the mission soon turns into a nightmare of impossible choices. The land of Guatemala, magical and cruel by turns, will prove much easier to enter than to escape...

Ultimate soldier. Ultimate mission. But will the SAS succeed in rescuing one of their own from a fearsome drug cartel? The end of 1980s sees the rise of the cocaine cartels of Colombia, criminal organisations as powerful as armies, whose malign reach stretches from the coca fields of Bolivia to the streets of London and New York. Needing help in the training of its elite Anti-Narcotics Unit, the Colombian Government turns to Britain and the legendary SAS. Two veterans are dispatched to Bogota. When one of them is kidnapped and held for ransom by the cartels, the only hope of securing his release seems to lie with the rest of the regiment back in England. Getting into Colombia will be hard enough. Getting out more perilous still, as the men of the SAS face dangers in every corner of a violent land, as they are pursued from the streets of Bogota, through the high mountains of the Andes, and on down into the Amazon rain forests.

Ultimate soldier. Ultimate mission. But can the SAS prevent the launch of Exocet missiles at the British Task Force? May 1982: as the British Task Force prepares to retake the Falkland Islands, a lone Sea King helicopter makes an apparently forced landing in the southernmost reaches of Chile. The only threat to the Task Force - and the enemy's only hope of ultimate victory - is Argentina's Super Etendard aircraft and their sea-skimming Exocet missiles. Since radar cannot be relied upon, the British must opt for a less conventional warning system. Before landing in Chile, the 'stray' Sea King drops a team of men into Argentina, where they are tasked with remaining hidden within sight of the airfields and within easy reach of the enemy's security patrols. Getting the men in is easy enough, but staying unobserved is another matter - and eventual escape will be next to impossible... Mission to Argentina tells the electrifying story of this SAS operation from the inside - a heart-stopping thriller about the regiment equalled by no other: the SAS!

Ultimate soldier. Ultimate mission. But can the SAS storm a fortress prison held by Muslim terrorists to rescue a group of British tourists? In 1994, in the newly independent state of Uzbekistan, a party of mostly British tourists is on a day excursion from the fabled city of Samarkand when Muslim fundamentalists hijack their bus. Unknown to the hijackers, this particular group contains recently retired ex-SAS sergeant Jamie Docherty, and the rebellious daughter of the British Foreign Minister, already a tabloid favourite back home. Uncertain how to respond to the terrorists' demands, the Uzbekistan government accepts a British offer of assistance: two members of the SAS crack Counter Revolutionary Warfare wing are dispatched to Samarkand, with instructions to liaise with the local ex-KGB unit. As the negotiations drag on, in the mountain fortress prison Docherty must call on all his formidable expertise and ingenuity to keep his fellow hostages alive, and to prepare them for a prospective rescue mission. The only force likely to have any chance of successfully penetrating the fortress and liberating the prisoners will be a group led by men of the legendary Special Air Service - the SAS!

Ultimate soldier. Ultimate mission. But will the SAS survive the Second World War, knowing that Hitler has torn up the rules of war? Early 1944, and with the tide of the war flowing steadily against the Germans, the SAS - born in North Africa as a strategic raiding force behind enemy lines - is performing a similar role in the Italian mountains and French forests. Here, after making common cause with local partisans, they are cutting rail and road links serving the frontline German armies. Hitler knows as much, and is determined that the SAS will pay a terrible price for their efforts. His infamous Commando Order decrees that any raiders captured behind enemy lines, whether in or out of uniform, will be summarily executed. Denied the safety net usually provided by the rules of war, the SAS embark on each new mission knowing that it will end either in success, or death.

Ultimate soldier. Ultimate mission. But can the SAS lead a civilian population out of war-ravaged Bosnia to safety? Bosnia, 1993. A small army of Serbs, Muslims and Croats, formed to defend the isolated mountain town of Zavik and under the command of Reeve, a renegade Briton, has begun mounting raids further afield in search of food, fuel and medical supplies. All sides in the civil war are enraged by its exploits; even UN mediators recognize the need for its suppression. But there are only two people Reeve will listen to: his ex-wife, and an ex-comrade in the SAS. The latter is willing to lead a team into Zavik; the former has first to be found - she is either trapped in Sarajevo or imprisoned in a Serbian concentration camp. Rescuing her is only the beginning. The SAS team will then have to traverse the mountainous war zone and force their way into the besieged town. This will be difficult enough. Fighting their way out of the war-ravaged territory with a convoy of the sick, the old and the very young will be next to impossible.

Ultimate soldier. Ultimate mission. But can just three members of the SAS quell a rebel uprising? July 1981: while Gambian President Jawara attends a royal wedding in London, Marxist rebels seize power. Fearing armed intervention from neighbouring Senegal, they take hostages - including one of the president's wives and several of his children - and empty the prisons in a desperate search for allies in the coming struggle. As opposing factions of the police force wrestle for control, prisoners settle old scores, slaughtering almost two thousand Gambians. In tourist beach hotels hundreds of Europeans fear the worst. At Jawara's request, three men of SAS 22 Regiment are sent into this cauldron, supposedly to advise the President and his Senegalese allies. But within days, they have become the spearhead of the counter-revolution, embroiled in both the pursuit of heavily armed criminals and the dangerously delicate business of rescuing hostages.
