A Rule Against Murder by Louise Penny.
This is the fourth in the Inspector Armand Gamache/Three Pines mystery series. Inspector Gamache and his wife Reine Marie to a country inn not far from Three Pines to celebrate their anniversary, which falls on Canada Day.
They are sharing the Manoir Bellechasse with Irene Morrow Finney and her family of adult children, who are having their annual reunion. This year is very special, as Irene is honoring her late husband by erecting a huge statue of him. When the statue falls on Irene's daughter Julia, killing her, Inspector Gamache is ideally placed to investigate.
One of Mrs. Finney's children is our old friend Peter Morrow from Three Pines, unwillingly in attendance. He and his siblings, equally unhappy, all come under suspicion for killing Julia.
In this wonderful example of the classic country house mystery, we not only learn more about some of the residents of Three Pines, we discover some of M. Gamache's history.
Louise Penny is an amazing writer, and her books just beg to be read in one sitting, which is extremely difficult to do when one must get up and go to work in the morning.
