This book is about Charles Cullen, a nurse who had a thing for killing patients. I was so excited to find this book at the used bookstore, because I had recently watched a series on television about nurses who kill. I ordered a couple, and then just randomly found this one. I wasn't bored by this book at all, and I thought it was pretty factual based on the things I learned from the show I watched. I agree with several other reviews that I read... the descriptions of his complexion were incessant and drove me nearly insane.
