Despite the coincidence in titles between this and any television shows I may be currently obsessed with, the book predates by a good long while.
Ehn. I have such mixed emotions about this book. It's shallow; it's erratic; it's confusing. The wikipedia entry on psychopathy is better than this book's subchapter. Dr. Ramsland spends a lot of time using TV shows and movies as examples of what to do or not to do with regard to accuracy of portrayals, and I would rather have had that space devoted to actual information on how a psychiatric evaluation of a suspect works, for example, with specifics rather than vague generalities.
On the other hand, as an overview of ways in which writers have made themselves look dumb, it's invaluable.
(I'm reading this book as part of my current brain-pack on psychoneurology, which is prereading for the sequel to Dust. Next up, some Ramachandran.)
