Former Chief Inspector Armand Gamache has retired from the Quebec police and is enjoying a peaceful retirement with his wife Reine-Marie in Three Pines. Life is serene with good food, company of friends, and social gatherings. But Clara and Peter Morrow have had a riff, agreeing to separate for one year and meet again to assess their relationship. After that one year Peter fails to return and Clara, in distress, seeks help from the good inspector.
Gamache and his prior associate Guy Beauvoir join with Clara and her friend Myrna in the search. They trace Peter’s journey from Quebec to Scotland then return to visit Peter’s art professor and family in Canada and end with a stormy voyage along the St. Lawrence. Strange paintings Peter left with a young relative may be important to resolve the mystery. Jealousies, danger, and storms plague the investigators throughout the search in Louise Penny’s The Long Way Home.
