Elisabetta Fezzi draws the portrait of an unknown Father Amorth through a series of private and unpublished conversations with the world's most famous. Father Amorth is multifaceted and curious by nature, not the gloomy and shady man as he often appeared, but an ironic and simple person, capable of joking and taking life as Providence offered him. Father Amorth recounts the decision to become a priest and the many small curiosities about his life and, above all, his mission as an exorcist: the fight against the devil.
