Query: interesting theory, but........

I'm an amateur ripper-ologist and am interested in who everyone thought did it, so I picked up Patricia's book at the local library. I was sadly disappointed. Patricia is an excellent writer, I'll give her that, but the way she put this book together made me think, "HUH?" She says, "Here's who did it," and that's about it. She had a theory and nicely fit all the facts around it, which is the WORST case of detecting I've ever seen. Every good detective, professional or amateur, knows that you never fit the facts to fit your theory. She doesn't even explain how she came to figure out Sickert was Jack. She just says, "He is, and here's why." I've read other books that gave just as compelling arguments for other suspects, but at least they explain why they believe their choices are right.Ah well, can't wait to get to heaven and find out who the real Jack the Ripper was. Believe me, it's the only way ANYONE's going to find out for sure.
