In Ian Caldwell’s masterful follow-up to his international sensation, The Rule of Four, a lost gospel, a contentious relic, and a dying pope’s final wish converge to send two brothers—both Vatican priests—on an intellectual quest to untangle Christianity’s greatest historical mystery.
In 2004, as Pope John Paul II’s reign enters its twilight, a mysterious exhibit is under construction at the Vatican museums. A week before it is scheduled to open, its curator is murdered at a clandestine meeting on the outskirts of Rome. The same night, a violent break-in rocks the home of the curator’s research partner, Father Alex Andreou, a Greek Catholic priest who lives inside the Vatican with his five-year-old son. When the papal police fail to identify a suspect in either crime, Father Alex, desperate to keep his family safe, undertakes his own investigation.
To find the killer he must reconstruct the dead curator’s secret: what the four Christian gospels—and a little-known, true-to-life fifth gospel known as the Diatessaron—reveal about the Church’s most controversial holy relic. But just as he begins to understand the truth about his friend’s death, and its consequences for the future of the world’s two largest Christian Churches, Father Alex finds himself hunted down by someone with vested stakes in the exhibit—someone he must outwit to survive.
