A Rule Against Murder by Louise Penny

Chief Inspector Armand Gamache and his wife, Reine-Marie, enjoy their time at the Manoir Bellechasse every summer. Regular guests for more than thirty years, it's a chance for the couple to unwind and relax. This year, the rest of the rooms in the rural Quebec inn are taken up by the Finney family, who can't seem to get along and find it hard to resist sniping at each other. It's no surprise, then, that one of the family is soon found dead (in a most intriguing way) and Gamache is joined by his colleagues, Inspector Guy Beauvoir and Agent Isabelle Lacoste, to try and uncover the murderer. Almost every Finney is a suspect, since they all disliked each other so much. Add in the staff of the hotel and it's obvious that Gamache has quite a case on his hands. Gamache's task is also complicated by the Finney family's dredging up details about his own father. A Rule Against Murder is the fourth book in the Armand Gamache series. A must for readers who like mysteries with lots of detail about the locale and a good puzzle.
