In creating this collection of cases at the intersection of psychology and law, author Margo C. Watt looked for diverse cases that had a particularly unusual element - cases that truly begged the question: "What kind of a person does such a thing?" The result is a casebook that offers intriguing and tantalizing answers to this question supported by evidence-based analysis. It is a welcome and informative addition to the library of anyone interested in the abnormal and criminal actions that may leave us scratching our heads about the nature of human behaviour. At the very least, readers will gain a better sense of how clinical forensic psychologists try to figure out why people do the things they do.
