Query: This book is all over the place

I just finished reading this book, and while there were some interesting points, it was difficult to read. The author is all over the place in this book. She jumps around in time and the events are hard to follow. Many things described in the book seem to have no relevance to the story. I can't say that she convinced me or didn't convince me. All I can say is that it's possible that she is correct in her enormous claim to have finally cracked the case, but she also may be way off base.I have to add that I think the size of her name on the cover of the book is a little much. Tone down the arrogance, Ms Cornwell.
