I liked the beginning of this books because I enjoy stories about police but...the details of the horse killing were repeated FAR too often. I still kept reading until about a third of the way in, we got dropped into a horse drama! WAY too much description! What everyone wore, what their horses looked like, blah, blah, blah...I have no idea if they found both killers or not. I gave up.
