Query: Cold Heart not up to the LaPlante excellence found in series

What a disappointment! Cold Blood and Cold Shoulder were such good reads. Then Cold Heart left me cold. What a stinker. The plot points rely on unbelievable coincidence that only amateur writers use. Not up to the typically high storytelling excellence of other LaPlante novels. It is so different in quality that I wouldn't be surprised to learn some day that LaPlante really didn't write this one.
