The Long Shot (Stephen Leather Thrillers)

Cole Howard of the FBI knows he has only days to prevent the audacious assassination—but he doesn’t know who the target is, or where the marksmen will strike. Former SAS sergeant Mike Cramer is also on the trail, infiltrating the Irish community in New York as he tracks down Mary Hennessy, the ruthless killer who tore his life apart. Unless Cramer and Howard agree to cooperate, the world will witness the most spectacular terrorist coup of all time.
