ALL THE DEVILS ARE HERE

Gamache goes to Paris.

Armand Gamache of the Sûreté du Québec has had an eventful time in Penny's last few books, taking over as Chief Superintendent, uncovering corruption at the highest levels, facing public scorn, and finally ending up back where he started, as head of the homicide division. Penny has always been a master of pacing on a serieswide level, moving between the overarching corruption story and more local mysteries and also occasionally taking a break from Three Pines, the beloved, unmappable Quebec village that is the main setting. This time around, Gamache and his wife, Reine-Marie, a retired librarian, are spending time in Paris, where both of their children now live, waiting for their daughter, Annie, to give birth to her first child with husband Jean-Guy Beauvoir, Gamache's former second-in-command. Gamache takes the opportunity to visit the Rodin Museum with his godfather, billionaire Stephen Horowitz, who then joins the extended Gamache clan for dinner—only to be hit by a car and almost killed as they leave the restaurant. Gamache is convinced it was no accident—an impression reinforced the next morning when he and Reine-Marie go to Stephen's apartment and find the place has been ransacked and there's a dead body behind the sofa. Soon the whole family is involved in the investigation, and everyone has a part to play, from Reine-Marie, who visits the Archives nationales, to son Daniel, a venture capitalist who moved to Paris to escape his father's shadow. Gamache calls on an old friend, the head of the Paris police force, but can he be trusted? As always, Penny's mystery is meticulously constructed and reveals hard truths about the hidden workings of the world—as well as the workings of the Gamache family. But there's plenty of local color, too, with a trip to the top of the Eiffel Tower to escape surveillance and a luxurious suite at the Hotel George V for good measure.

If you're new to Penny's world, this would be a great place to jump in. Then go back and start the series from the beginning.
