When an intricate old map is found stuffed into the walls of the bistro in Three Pines, it at first seems no more than a curiosity. But the closer the villagers look, the stranger it becomes. Given to Armand Gamache as a gift the first day of his new job, the map eventually leads him to shattering secrets. To an old friend and older adversary. It leads the former Chief of Homicide for the Sûreté du Québec to places even he is afraid to go. But must. And there he finds four young cadets in the Sûreté academy, and a dead professor. And, with the body, a copy of the old, odd map.

When a peculiar letter arrives inviting Armand Gamache to an abandoned farmhouse, the former head of the Sûreté du Québec discovers that a complete stranger has named him one of the executors of her will. Still on suspension, and frankly curious, Gamache accepts and soon learns that the other two executors are Myrna Landers, the bookseller from Three Pines, and a young builder. None of them had ever met the elderly woman. The will is so odd and includes bequests that are so wildly unlikely that Gamache and the others suspect the woman must have been delusional. 

It’s Gamache’s first day back as head of the homicide department, a job he temporarily shares with his previous second-in-command, Jean-Guy Beauvoir. Flood waters are rising across the province. In the middle of the turmoil a father approaches Gamache, pleading for help in finding his daughter. As crisis piles upon crisis, Gamache tries to hold off the encroaching chaos, and realizes the search for Vivienne Godin should be abandoned. But with a daughter of his own, he finds himself developing a profound, and perhaps unwise, empathy for her distraught father.

Hardly a day goes by when nine-year-old Laurent Lepage doesn't cry wolf.

Including Armand and Reine-Marie Gamache, who now live in the little Quebec village.

On their first night in Paris, the Gamaches gather as a family for a bistro dinner with Armand’s godfather, the billionaire Stephen Horowitz. But an attempt on the elderly man’s life sends Armand, his wife, Reine-Marie, and his former second-in-command at the Sûreté, Jean-Guy Beauvoir, from the top of the Tour d’Eiffel, to the bowels of the Paris Archives, from luxury hotels to odd, coded works of art. It sends them deep into the secrets Armand’s godfather has kept for decades.

Happily retired in the village of Three Pines, Armand Gamache, former Chief Inspector of Homicide with the Sûreté du Québec, has found a peace he'd only imagined possible. On warm summer mornings he sits on a bench holding a small book, The Balm in Gilead, in his large hands. "There is a balm in Gilead," his neighbor Clara Morrow reads from the dust jacket, "to make the wounded whole." While Gamache doesn't talk about his wounds and his balm, Clara tells him about hers. Peter, her artist husband, has failed to come home. Failed to show up as promised on the first anniversary of their separation. She wants Gamache's help to find him. Having finally found sanctuary, Gamache feels a near revulsion at the thought of leaving Three Pines. "There’s power enough in Heaven," he finishes the quote as he contemplates the quiet village, "to cure a sin-sick soul." And then he gets up. And joins her.
