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. 

When a mysterious figure appears in Three Pines one cold November day, Armand Gamache and the rest of the villagers are at first curious. Then wary. Through rain and sleet, the figure stands unmoving, staring ahead. From the moment its shadow falls over the village, Gamache, now Chief Superintendent of the Sûreté du Québec, suspects the creature has deep roots and a dark purpose. Yet he does nothing. What can he do? Only watch and wait. And hope his mounting fears are not realized.

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.

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.

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

No outsiders are ever admitted to the monastery of Saint-Gilbert-Entre-les-Loups, hidden deep in the wilderness of Quebec, where two dozen cloistered monks live in peace and prayer. They grow vegetables, they tend chickens, they make chocolate. And they sing. Ironically, for a community that has taken a vow of silence, the monks have become world-famous for their glorious voices, raised in ancient chants whose effect on both singer and listener is so profound it is known as “the beautiful mystery.”

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.
