The year is 1944. Just outside Delhi, a British Dakota crashes, taking lives and destroying a clandestine treaty signed by Lord Mountbatten and the Communist leader, Mao Tse-tung. A historic agreement, one set to change the course of history. Over 30 years later, a deathbed confession from a Mafia kingpin reveals the answers to untouched secrets about the treaty and just how much the British and Chinese governments would pay for its destruction. It's not long before Sean Dillon enters the fray.

Sean Dillon is a hired killer. The IRA, the PLO, ETA - he's worked for them all. Now, with the Gulf War raging, the Iraqis need his services for an apocalyptic strike at the heart of the West. If it succeeds, it will shake the world to its foundations. Leaders will be wiped out, terror will spread: a devastating blow against democracy. Dillon has 10 Downing Street in his sights, but British intelligence are on his trail. They have hired a killer to stalk a killer - a mortal enemy who is hell-bent on revenge.

Twenty years ago a young war hero saved a life and began a passionate affair. Now that young war hero is president of the United States, and a souvenir from his past, a beautiful daughter he never knew existed, surfaces as the first of many secrets to be kept from public knowledge. But someone, somewhere, has uncovered the truth. The girl is seized by religious zealots, and unless the president complies with their demands, her execution is certain. Yet if he gives in, the Middle East will ignite in war. He calls in the only men who can help: Sean Dillon and Blake Johnson.

A fortune in stolen British gold, brutally hijacked by Irish Protestant paramilitaries in the 1980s, lies shipwrecked at the bottom of the Irish Sea. Now the Irish Rose and her precious cargo have been found. The race is on to recover the bullion. Irish militant Michael Ryan wants to finance war in his homeland - and a sinister pact with the New York Mafia will make his dreams a savage reality. To stop him the British and American authorities must call in the best: Sean Dillon, once the most feared IRA enforcer, now working for British Intelligence.

New York: a woman waits in the shadows, a Colt .25 in her elegant hand. Her target: Senator Michael Cohan, member of an extremist organization dedicated to destroying the peace talks. Run by Britain's most wanted terrorist, Jack Barry, its secret links stretch all the way to the Oval Office. Washington: the president calls Blake Johnson, head of secret White House department 'the Basement'. He needs to see him now.

In the waning days of World War II, Hitler entrusted his diary to a young aide, Baron Max von Berger. Over the years von Berger has used his inheritance to become one of the richest men in the world, developing a secret alliance with the Rashid family - longtime foes of Major Ferguson of British Intelligence; his undercover enforcer, Sean Dillon; and their American colleague, Blake Johnson. Now the ultimate confrontation is drawing near.

The murderous Rashid family were forced to pay the ultimate price for their crimes by the British government's secret enforcer, Sean Dillon, and his undercover team. Yet one member of that oil-rich dynasty was allowed to live, and that could have been Dillon's fatal mistake. Kate Rashid witnessed her brothers being killed one by one, and now she has sworn vengeance. Sean Dillon, White House operative Blake Johnson, even the US president himself...their time is coming, and only she knows how - or when.

Sean Dillon in his most spectacular adventure yet, a no-holds-barred battle with a Mafia don. When the Mafia kill a reporter for getting too close, White House security insider Blake Johnson takes it personally. The reporter was his ex-wife, and with the help of undercover enforcer Sean Dillon and his intelligence colleagues he is hell-bent on revenge. In London, Beirut and Ireland, the daredevil friends risk everything as they combine to destroy the illegal businesses of Mafia front man Jack Fox.

On the 30th April 1945, Russian radar reported a light aircraft leaving the vicinity of the Tiergarten in Berlin. But who was on board, and where was the plane going? Berlin was in ruins as the Russians moved relentlessly towards the concrete bunker where the Nazi administration had been destroyed. But one man, Reichsleiter Martin Bormann, Adolf Hitler’s secretary and eminence grise, had a daring plan to escape.

It is night in Manhattan. The president of the United States is scheduled to have dinner with an old friend, but in the building across the street a man has disabled the security and stands at a window, a rifle in his hand. The assassination doesn't go according to plan, but this is only the beginning. Someone is recruiting a shadowy network of agents with the intention of creating terror. Their range is broad, their identities masked, their methods subtle.

In the early morning hours of 6th November 1943, SS Reichsfuhrer Heinrich Himmler, receives the coded message he has been waiting for, 'the Eagle has landed.' It was to become known as the most daring enemy mission of the entire war: Operation Eagle, Himmler's audacious plan to kidnap Winston Churchill on British soil. But, despite spectacular secrecy, there was to be no surrender without a fight. For in that remote corner of Norfolk, an elite unit is gathered together. Ready to do battle for a nation against the most ruthless taskforce ever assembled.

In Ulster, Northern Ireland, a petty criminal kills a woman in a drunken car crash. Her sons swear revenge. In London, Sean Dillon and his colleagues in the 'Prime Minister's private army', fresh from defeating a deadly al-Qaeda operation, receive a warning: 'You may think you have weakened us, but you have only made us stronger'. In Washington, DC, a special projects director with the CIA, frustrated at not getting permission from the president for his daring antiterrorism plan, decides to put it in motion anyway. Soon the ripples from these events meet and overlap.

Whilst checking up on the volatile situation in Kosovo, the US president's right-hand man, Blake Johnson, meets Major Harry Miller, a member of the British Cabinet. Miller is there doing his own checks for the British Prime Minister. When both men get involved with a group of Russian soldiers about to commit an atrocity, Miller puts an end to the scuffle with a bullet in the forehead of the ringleader. But this action has dire consequences not only for Miller and Johnson but for their associates, too.

Somewhere in Germany was hidden a manuscript that would rock Western Europe to its foundations: the testament of Caspar Schulz. Once a prominent Nazi, and long believed to be dead, Schultz could soon be hailed as the author of the most shattering confessions ever to make print.

Putin and the Russians have suffered too many killings of their own people in the past. Now they want the whole of the 'Prime Minister's private army' wiped out, including Blake Johnson and Charles Ferguson. Somebody is after them: Blake, Harry Miller, his sister, Monica, Harry Salter and Billy. The only people spared are Roper and Dillon. After surviving a car bomb, Ferguson heads a desperate search to uncover the perpetrator.
