This book is just great. One of the best specialist books I have ever read. You know was the best thing is? It's objective. Most of authors -especially crime authors- have a particular view of things. They can only attempt to write as objectively as possible and in doing this indicate their personal opinion as such. That is not case here. The Authors of this book present the facts in some detail but without ever pronouncing judgment. For someone who would like to read about the crimes of Jack the Ripper without any influence it's the best book ever.
