"Rx" by Alan Edward Nourse is a science fiction novel written in the mid-20th century. The book follows the story of two Earth doctors, Sam Jenkins and Wally Stone, as they respond to an emergency call from the journalist Morua II, a planet with a troubled history of refusing medical contracts with Earth. The primary theme revolves around the challenges of providing medical assistance in a foreign and hostile environment, highlighting the complexities of cultural understanding and the nature of healing. The narrative kicks off with a crash-priority call that brings the medical team aboard the General Practice Patrol ship "Lancet" to the chaotic world of Morua II. Upon their arrival, they are immediately faced with the dying "Tenth Son of a Tenth Son," whose illness has baffled the local witch doctors. Faced with potential danger and unrest among the Moruans, Jenkins relies on a blend of modern medicine and cultural theatrics to treat the ailing leader. Through clever improvisation and an understanding of both medical science and the Moruan belief system, Jenkins manages to stabilize the emperor's condition, ultimately forging a medical contract with the Moruans. The ending emphasizes the significance of time and patience in medicine, concluding that healing is often as much about cultural connection as it is about treatment.
