Dark Pattern by Andrew Mayne

4.0

Once again, Theo is searching for a serial killer that most people don't think exists. This time, he's after a nurse that leaves behind several dead patients when she leaves a hospital. Children, homeless men, it doesn't seem to matter to her -- she likes taking lives. This time Theo is going to have to do some serious investigation though, including some method acting, all while brushing off the relationship (s) in his life.

I enjoy the science behind these books and the way in which Theo gets obsessed. He's kind of a jerk, yet, he's great at finding serial killers.
