Query: The Cat Who Disappointed a Reader

I have read every Cat Who book written by this author, and I feel this is the weakest book in the series! All of the other books had twists and turns in the plot, and all of the other books had the ability to keep you guessing until the very end. Unfortunately, in this book, the author chooses to dwell on character development and background material. As a fan of the series, I did not need this additional information - I already love Qwill, Koko and Yum Yum, without knowing the ins and outs of Scottish games or mechanical banks! I hope that the next book in the series sees a return to a real mystery, and not just a walk down memory lane! If you have enjoyed the other books in this series, you will find this entry acceptable, but it will probably not be one of your favorites. If you have never read one of the Cat Who books, or if you have read only a few, I would recommend reading the earlier books before this one.
