Baie-Saint-Paul
The Long Way Home reference: Gamache, Jean-Guy, Myrna, and Clara visit the town.
Real world location: Baie-Saint-Paul is located in the Charlevoix region of Quebec. Rue Saint-Jean-Baptiste is the main thoroughfare and is filled with galleries and restaurants. In the summer, street entertainers, artists, films and outdoor concerts bring it to life.
Louise Penny writes in her acknowledgements that "I recognize that the Baie-Saint-Paul of this book is not "a completely accurate reflection of the actual town. I hope those of you who live there, or visit that lovely area, forgive me some artistic license."
