"When Tribal Police officers find a badly decomposed body nailed to the west wall of an abandoned ranch house on the mammoth Fort Apache Reservation in northern Arizona, Troy and Amber Barclay are called to the scene. After examining the body, Dr. Amber Barclay estimates it has been on the wall for six weeks but subsequent evidence shows the person was alive two weeks earlier. An autopsy reveals the person was poisoned with ‘sorcerer’s poison’ which connects it to three unsolved murders from four years earlier and also explains the rapid decomposition."
