An Amish farmer, believing the spirit of his beloved, dead horse still roams near his farm, is beset by unexplained troubles in his dairy herd. As the health of his cattle wanes, he is convinced that the problems are linked to the horse's ghost. In this novel, the sequel to Casting Demons Into Swine , and Prometheus Scorned , Malcolm Cromarty, DVM, encounters animal healing rituals and remedies that seem to be rooted more in sorcery than medicine. Following the diagnostic trail, he begins to realize that the animal health issues involve more than a single farm, and there are forces at play that go beyond superstition and coincidence.
