About the book: 2019 / The story of Charles Cullen, a serial killer who confessed to authorities that he killed about 400 patients during his sixteen-year career as a nurse. He is called the "Angel of Death". He administered lethal doses of drugs “to relieve the suffering” of his victim patients. Charles Graber investigates the causes and consequences of this “chilling” case, as Stephen King himself called it. A film based on the events outlined in the book is planned soon.
