After his arrest in 2003, 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 favourite 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.

Chronicling Cullen's deadly career and the breathless efforts to stop him, The Good Nurse paints an incredibly vivid portrait of madness and offers an urgent, terrifying tale of murder, friendship and betrayal.
