"After his December 2003 arrest, registered nurse Charlie Cullen was quickly dubbed "The Angel of Death" by the media. But Cullen was no mercy killer, nor was he a simple monster. He was a favorite son, husband, beloved father, best friend, and celebrated caregiver. Implicated in the deaths of as many as 300 patients, he was also perhaps the most prolific serial killer in American history. Cullen's murderous career in the world's most trusted profession spanned sixteen years and nine hospitals across New Jersey and Pennsylvania. When, in March of 2006, Charles Cullen was marched from his final sentencing in an Allentown, Pennsylvania, courthouse into a waiting police van, it seemed certain that the chilling secrets of his life, career, and capture would disappear with him. Now, in this piece of investigative journalism nearly ten years in the making, the author, a journalist presents the whole story for the first time. This work does more than chronicle Cullen's deadly career and the breathless efforts to stop him; it paints an incredibly vivid portrait of madness and offers a penetrating look inside America's medical system."-- Publisher marketing.
