Query: Heart not in it.

I have read all of the Matthew Hope series, and have always enjoyed them thoroughly, until now. I found this book just drifted along, and neither the main character or the author really seemed to have their heart in it, so I'm not quite sure why they bothered. I did not find the plot interesting at all, and the writing style was disjointed and unfeeling. I was very disappointed. I hope the new 87th Precint book, which I have sitting in my 'to be read' pile is better than this.
