Case closed? Hardly.Cornwell's "book" is all conjecture and supposition. It is a completely ridiculous book with no factual basis for anything that she believes to be true. At least she has stuck to what she does best: fiction.If you are going to read anything about Jack the Ripper, then read any other book on the subject. There are tons of horrid books about Jack, but they are still better than this load of dung. For people who really want to learn about and read some excellent books on the subject, pick up anything by the following authors: Philip Sugden, Donald Rumbelow, Keith Skinner, or Stewart Evans.This book is horrid for true students of the case because Cornwell, with this pathetic stinker of a book, has put in the minds of casual readers that the Ripper case is solved when it is so obviously not. Ugh...she and this book make me want to vomit.
