So true that Ann Rule is teaching, how to read people and recognize sociopaths. Her granddaughter was my now deceased daughters best friend. I was so jealous when she got to spend the night at Ann's house, both girls thought I was crazy, her granddaughter has never read her books, calls them too creepy. I did get an autographed book from her though, I treasure it, she writes so so well. She has a website called annrules.com, very interesting look at a busy and very nice lady.
