For his 2009 book "The Rite: The Making of a Modern Exorcist," author Matt Baglio explored an exorcism class at a Vatican-sponsored university in Rome.
For 2012's "Argo: How the CIA and Hollywood Pulled Off the Most Audacious Rescue in History," Baglio and co-author Antonio Mendez took a deep dive into Mendez's hair-raising 1979 rescue of six American hostages from the American embassy in Tehran. That rescue inspired the film "Argo," which won a best-picture Oscar in 2013.
Having dealt with the Vatican and the CIA, Baglio knew how to handle big, secretive bureaucracies. But he was still not prepared for the challenges presented by Fox Lake, Illinois, a small town with a scandalous story it did not want Baglio to tell.
