Even ghosts need help from a Cunning Man. Hiram and his son Michael are dowsing a well in Eastern Utah when they hear a cry of help from the ghost of a small boy, torn to pieces by wild animals. Before they can even begin to look into that tragedy, however, a prosperous local rancher is murdered right before their eyes. In an attempt to both help the ghost and find the killer, Hiram and Michael must navigate an eccentric cast of characters that includes failed bank robbers, a seductive fortune-teller, an inept sheriff, a crazy prospector, and a preacher with an apocalyptic grudge against the Roosevelt administration. The mystery, however, isn't just in the hearts of men. There's an astrological puzzle that Michael, now his father's apprentice, must solve. Meanwhile, the murderer is moving slowly against Hiram and Michael, forcing them into a trap from which there is no escape.
