An Amishman, believing that the spirit of his beloved, dead horse still roams about his farm, is beset by unexplained troubles in his dairy herd. As the health of his cattle wanes, his conviction that the problems are linked to the horse’s ghost increases. In this novel in the Coigreach Trilogy, the sequel to Casting Demons Into Swine, and Prometheus Scorned, Malcolm Cromarty, DVM, confronts animal healing rituals and remedies that seem to be rooted more in sorcery than medicine. Once again, he follows a trail of suspense, within a deceptively tranquil valley, with a singular culture and terrain. As time passes, he realizes the peculiar animal health issues involve more than a single farm, and there are forces at play that go beyond superstition and coincidence.
