The Unspeakable tells the story of two men, both priests, whose strange and divergent paths collide. Peter Whitmore, an administrator for the Diocese of St. Paul, is asked to investigate and ultimately discredit a priest who, it is rumored, possesses a remarkable power—the power to heal.
The priest in question, Jim Marbury, is no stranger to Whitmore. He is an old friend, a seminary roommate, and a spiritual mentor whom Whitmore has not seen in more than twenty years. But much has changed. Always somewhat unconventional, Marbury is now mute, speaking only in sign language, his voice reportedly stolen by God on a trip that he took through western Pennsylvania. On that same journey, in a snowstorm that nobody can verify, Marbury encountered a terrible car accident and a family who changed his life irrevocably.
Marbury gets drawn into a world he did not expect—a world where the past repeats itself, where the mystical is not in a book but alive and breathing. And now Whitmore, his old friend, has to decide for himself which events are really the hand of God and which are the delusions of Marbury gone mad.
