Not too bad. I did not guess the killer until close to the end, which is good, as you can often tell who is going to be the bad guy in the first chapter or two. But the action was slow. It is kind of a one event book. An old woman is found dead. The rest of the book just sort of deals with that event. OK bit not great.
