Washington, DC, police detective Peter Gallagher is called to investigate the death of a young Jesuit priest in what appears a tragic accident. What he uncovers, instead, is far more complicated: the legacy of a Cold War political conspiracy, involving Washington power brokers, the CIA, and the secret inner workings of the Vatican. In a desperate race to reveal the truth, Gallagher joins forces with the young and beautiful Laura Miller, the daughter of an American ambassador. Together they embark on a dangerous journey through Washington, DC, and into Central America, risking their careers, and their lives, while spies, politicians, and prelates attempt to outmaneuver one another in a battle for temporal and spiritual power. Throughout it all, the competing sides in this deadly struggle justify their own clandestine actions with the most important, and only, motivation shared among them all. They call it: The Greater Glory.
