I just received this book about a week ago. It is the best book you can find on psychopathy. It is well written, with each chapter flowing from one to another in a coherent manner. It provides a good historical account of psychopathy and what I really enjoyed was the chapters on fMRI and neurobiology studies! I only wish there had been more of neurobiology and legal scholarship. This book is not a "pop" psychology book, rather it is for academics and researchers -- thank goodness!
