The Long Way Home, Penny - C

                                               This the tenth book in the series. By now, Gamache and his wife are retired and living comfortably in Three Pines. One of their neighbors, Peter Morrow, was asked by his wife to leave and to come back exactly in a year so they could assess where their marriage stood. Clara had usurped Peter's role as the most famous painter in Canada and he had not reacted well. His failure to return leads to a search by the now private citizen and former Chief of the Surete, Homicide Division for Quebec Province.  The search meanders through the area east of Montreal along the St. Lawrence and delves deep into the Canadian art scene. It involves revenge and a long-distance murder utilizing a toxic substance. For whatever reason, this one didn't work for me. I believe I'll call it a day on this series.
