Dr. Pendergast Investigates; it goes with the territory. Frontier doctors of the late 19th century were the quintissential general practitioners. They brought children into the world and they struggled to keep their neighbours alive in the face of threats which included disease, accidents, natural disasters, and in the troubled times, the occasional gunshot wound. Doctor Robert Pendergast is the town doctor of a small mining and agricultural community. The town was known as Red Rocks until 1906 and as Sedona, Arizona today. 1906 was the year of the San Francisco earthquake, an event of the type referred to as an Act of God. For the townsfolk of Sedona, death came to their community that year by the hand of man. Dr. Pendergast turns his talents to the solution of a problem which pits his deductive and resolvent skills against madness and worse.
