content: Great book for anyone interested in true crime and the criminal mind. John Douglas looks at some classic crime cases using his profiling method: look at the facts of the crime and draw conclusions about what kind of person could have done it. This is in contrast to the approach of: identify a likely suspect, then identify facts of the crime that fit the suspect. The author does not claim to solve all of the cases he studies in this book, but rather point us in the right direction. For example, he describes the likely personality characteristics and behavior of Jack the Ripper (interestingly this does not seem to match Patricia Cornwell's conclusion) and the Zodiac. His discussion of the Ramsey case is probably the most controversial since he was personally involved in the case. A well written and interesting book.
