Nonfiction about narcissists, pathological liars, or other serious personality disorders

I'm looking for readable nonfiction about personality disorders or other fascinating or disturbing mental health conditions, maybe similar to The Psychopath Test by Jon Ronson (which I've already read).

I'm not interested in self-help type books about coping with narcissist parents, dealing with the BPD person in your life, setting boundaries, etc. I'm more looking for books about the science of these disorders, interesting facts, common themes and behaviors, case studies, anecdotes, history.

Mostly interested in the darker disorders/traits, associated with immoral or amoral behavior, not so much in ADHD, autism, OCD, bipolar disorder, etc.

Topics like:
* Narcissism
* Pathological lying
* Factitious disorder/Munchausen (self or by-proxy)
* Sociopathy/ASPD
* Paranoia
* Maybe BPD

I know there's a book about narcissism written by a scholar who is himself a narcissist, but I've heard it's a little obnoxious to read for the obvious reasons.

Anybody got any recs?
