Query: Enormously disappointing

I expected this book to be a suspenseful, entertaining read. I also expected, given Mr. Patterson's reputation, that it would be a well-plotted and well-written book. I was enormously disappointed. At the very least, when I finish a suspense book, I expect to know exactly who the killer is and why the killer did it. Mr. Patterson gives a confused and thoroughly unbelievable conclusion to an unconvincing story. The plot holes are troublesome, too. (Example: who IS the character in Chapter 17?) I don't like the presentation of many of the women in this book, and I find them implausible, too. I was looking forward to this series. Given the weakness of this first entry, however, from its gimmicky open to its confusing close, it's the last in the series for me.
