When I first heard about this book and the theory it put forward I was rather excited as the idea the Jack was not as everyone has pictured for the last 128 just tickles me, and knowing how vicious female murderers can be at first blush this theory has serious credence. But on reading it I was rather disappointed. Morris and his father seem to have started with their conclusions and worked backwards hand picking the evidence the supports it (or that can be interpreted in such a way as to support it) and ignoring the evidence that undermines it. Not to mention making some rather large assumptions with nothing to back up their reasoning (or the lack there of). The only thing that saves this book is the writing which has a lovely fireside story telling feel to it, kind of how the gossips of old talked when Jack was stalking the streets. Great idea but poor execution (pardon the pun) lacking research and evidence (such a shame).
