Mack Bolan's mission begins with information retrieval. He must find out who is using terrorist threats to force U.S. intervention in Northern Ireland. Evidence piles high against the Protestant Orange Order, which wants the world to endorse the existence of two Irelands. But when the Executioner uncovers a plot to launch a dirty bomb on American soil, the true threat—and the real face of the deadly enemy—comes under his lethal and personal attack.
