Despite his recent divorce and being new to the valley, the career of Malcolm Cromarty, D.V.M., was finally settling into a routine. After all, life among cows, stoic dairy farmers, and a steadfast dog tends to be rather mundane, especially when bolstered by an occasional ‘wee dram’ of single malt. However, the daily grind veers off course with the arrival of a disease outbreak that seemingly doesn’t stay on message with the textbooks. To cope with this challenge, Malcolm must rely on a patchwork of inhabitants to guide him through the peculiar culture in which he lives. The problem is that while some of the locals are helpful, others have their own motives and engage only within their limits of religious dogma, or are outright hostile. With each passing day, Malcolm stumbles deeper into a community that holds science, change, and outsiders under a high degree of suspicion, and a family feud with a dark and malevolent past. Hardly a promising path to resolve the outbreak and avoid tragic consequences.

An unrelenting sun beats down, bringing drought and hardship to the farmers in the valley. As if lost crops weren’t enough, a series of suspicious barn fires pushes the community to its limits. In this novel, the sequel to Casting Demons Into Swine, Malcolm Cromarty, DVM, once again gets caught up in a complex web of suspense, strung across a deceptively tranquil valley, known for its singular culture and terrain. As the dry spell and fires continue, the unfolding tragedy seeps deeper into Malcolm’s life, forcing him to confront some of the darker elements of human nature. Although fiction, the books in this series are based on true events experienced by the author RJ Erskine, once a practicing veterinarian in a rural Pennsylvania community.


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, 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.
