Written in nearly the same vein as P. D. James, it is the seventh in a series, that again, I did not know about. I'll have to seek out the first four, and maybe the rest, if there's any.
One reason I like to read police procedurals is to witness the camaraderie (or lack of) between the men and women who patrol and investigate their community, as well as their relationship to the community. It makes for compelling reading if done correctly. Since this book focused on the protagonist's grief, it was not in evidence here. But, it just gives me a reason to do what I stated above.
