The Good Friday agreement that promised to bring peace to the embattled Protestants and Catholics of Northern Ireland is jeopardized by a new paramiltary group bent on destroying the truce. Michael Osbourne, the hero of Silva's previous thriller, The Mark of the Assassin, is rerecruited by the CIA when Douglas Cannon--his father-in-law, a former senator, and the new ambassador to the Court of St. James--is targeted for death by the Ulster Freedom Brigade. Osbourne … mehrhas long since given up on the spying game and is reluctant to be drawn back into it again. Then he discovers that the Brigade has shopped the contract on Senator Cannon to October, the assassin who narrowly missed killing Osbourne a few years ago but succeeded in murdering the woman he once loved. It's a good setup for a political thriller, with nonstop action that moves from Belfast to Armagh, New York to Washington, London to Mykonos. What really notches up the suspense is the double-dealing in the corridors of power, particularly the CIA and a secret organization called the Society--a nasty assemblage of politicos, spymasters, arms merchants, and killers bent on destabilizing nascent peacemaking efforts all over the globe. Down but not out at the conclusion of Silva's latest, the Society and Osbourne will likely be back for a return engagement the next time warring factions attempt to beat their swords. In fact, as the director of the Society says in the last chapter, "The Kosovo Liberation Front would like our help: Gentlemen, we're back in business." --Jane Adams weniger
