Book excerpt: Dr. Jack Culver is the medical director of a rehabilitation unit in a small town hospital in southern Illinois. After six rehabilitation inpatients die in one quarter, he becomes convinced that a serial killer is loose in the hospital. He and Rickie Davis, a rehabilitation nurse, are the only ones who believe the deaths were murders. In an attempt to convince the hospital that a serial killer exists and must be stopped, Culver risks his reputation, financial stability, and even his health. The book follows Culver through a startling series of events in which he bravely loses most of what he holds dear in life, and even faces his own death in uncovering a serial-killer conspiracy. Follow the hero and see what happens when he sticks to his beliefs in the face of overwhelming criticism and personal loss. The story accelerates into a surprise and bloody ending. Readers will enjoy the author's refreshingly different approach to medical mystery writing, and will find the book educational, spine tingling, inspiring, difficult to put down, and a must read.
