Keep Calm

 A Fatal Grace is Louise Penny's second novel. The major protagonist, Chief Inspector Gamache, is still establishing what kind of person he is, to the reader. I for one like what he is, i.e., honest, kind, strong, and loyal. He is dealing with a team of detectives who at times are incompetent, disloyal, and confused. He's trying to solve two murders.

One is a tradition, in that, every year he choses one cold case to solve. While dealing with that, there's another murder in Three Pines. The little village is working its way into his heart.
An obnoxious women has been murdered by electrocution. No one mourns her demise and her murderer could have been one of three people but it ends up a surprise. Lo and behold, she is related to the cold case, Gamache is trying to solve. Both are related in surprising ways.
Their are hints of trouble to come to Gamache, in future novels. He makes a deal, which the reader doesn't know about, with one of his agents. Another agent may be disloyal. We will find out in another mystery. But Gamache and his wife end with satisfaction that they've made the world a safer place.
