" Alex Morse, an FBI agent, renowned for her hostage negotiation skills, believes that her sister has been murdered by a partnership of contract killers made up of a divorce attorney (who offers an alternative to a messy divorce) and a doctor (who claims to be able to kill without leaving a trace of forensic evidence, inducing cancer in his targets) at the behest of her sister's husband. She has nothing that can initiate an FBI investigation, so she goes rogue, undertaking the investigation on her own. She identifies the next victim, Dr. Chris Shepard from Natchez, and convinces him to help her. Her rogue investigation is discovered, and she loses her job, yet she persists, obtaining the assistance of an FBI agent friend and her late father's PI partner. The outcome is fraught with action. Typical Iles work, and well done. "
