Sean Dillon is a master terrorist, an elusive, mysterious figure whose skills surpass even those of famed international fugitive Carlos the Jackal. For years Dillon has slipped through the hands of authorities on every continent, hiding in the anonymity of the underworld. But it is during the Gulf War, when Saddam Hussein is feeling the grip of the British and American forces closing in on him, that Dillon once again emerges -- right into the eye of Saddam's storm.
Hired by Iraqi operatives to strike a blow against the allied forces, Dillon plots an attempt on Margaret Thatcher's life. His ultimate goal, though, is a mortar launch against the War Cabinet during a meeting at 10 Downing Street. As Dillon's plan progresses, his longtime nemesis Martin Brosnan, an American Special Forces hero who has known Dillon from his IRA days, is recruited by British intelligence to nail him. Just as Dillon is within Brosnan's grasp, he slips away again. Step by step, a deadly cat-and-mouse game unfolds, although the odds are stacking up against Dillon's capture.
