I read the Good Nurse five years ago and I consider it one of the best true crime books that I have ever read, and I have read well over three hundred of them.Charles Cullen is the good nurse in question here. The lunatic worked at several hospitals and a nursing home, leaving a trail of death behind.Finally, after fifteen years and a number of untimely and suspicious deaths, one courageous nurse voiced her feelings to a pair of tenacious detectives.A Catholic priest was one of Chuckie's murders and after being exhumed, the good reverend had a high level of the heart medication Digoxin in his body.The recordings of Cullen are riveting and I only wish that more of them had been used in the film.I highly recommend both the book and the film.
