Named after a Mormon saint, Moroni may be Salt Lake City's only Gentile private eye still maintaining uneasy contact with the Church of Latter-day Saints. His eighth case finds the former pro football player reluctantly accepting a charge from one of the church leaders to investigate the enigmatic, self-effacing faith healer Jason Thurgood. Traveler's commission takes him downwind of the old atomic testing sites to the desolate southwest corner of Utah, commonly known as cult country because of the longtime activity of various polygamists and self-proclaimed prophets there. Currently the area is under the sway of Moroni's Children, a cult headed by ruthless, power-hungry Orrin Porter. At the same time, Moroni's father and partner, Martin, is working on a missing persons case involving the young mentally-handicapped son of an old friend just across the border in Nevada. Oddly, the two cases begin to converge, and the Travelers realize that the superficial answers they seek mask darker, more complex forces at work.
