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.”

Hardly a day goes by when nine-year-old Laurent Lepage doesn't cry wolf. From alien invasions to walking trees to winged beasts in the woods to dinosaurs spotted in the village of Three Pines, his tales are so extraordinary no one can possibly believe him. Including Armand and Reine-Marie Gamache, who now live in the little Quebec village.

Shadows are falling on the usually festive Christmas season for Chief Inspector Armand Gamache. When Gamache receives a message from Myrna Landers that a longtime friend has failed to arrive for Christmas in the village of Three Pines, he welcomes the chance to get away from the city. Gamache soon discovers the missing woman was once one of the most famous people not just in North America, but in the world, and now goes unrecognized by virtually everyone. As events come to a head, Gamache is drawn ever deeper into the world of Three Pines.

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 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.

Welcome to winter in Three Pines, a picturesque village in Quebec, where the villagers are preparing for a traditional country Christmas, and someone is preparing for murder. No one liked CC de Poitiers. Not her quiet husband, not her spineless lover, not her pathetic daughter - and certainly none of the residents of Three Pines. CC de Poitiers managed to alienate everyone, right up until the moment of her death. When Chief Inspector Armand Gamache, of the Sûreté du Quebec, is called to investigate, he quickly realizes he's dealing with someone quite extraordinary.

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.

When a sadistic killer begins picking off victims on the streets of Inverness, Jack’s boss decides to bring in some outside help. But the new team member is an old flame from Jack’s past who isn’t quite ready to let him go.

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.

On the tree-lined banks of Surrey’s River Wey, a decaying corpse is dug up by workmen in the middle of an Anglo-Saxon burial site. His modern dental fillings show that this is no Dark Age corpse. DCI Craig Gillard is called in, but the body’s condition makes identification difficult. One man, however, seems to fit the bill: Ozzy Blanchard, a contractor employed by the same water firm doing the digging who disappeared six months ago. But then an X-ray of the corpse throws the investigation into turmoil. The deeper Gillard digs, the more shocking truths he will uncover.

Police officer Sebastian Clifford never planned on becoming a private investigator. But when a scandal leads to the disbandment of his London based special squad, he finds himself out of a job. That is, until his cousin calls on him to investigate her husband’s high-profile death, and prove that it wasn’t a suicide. Clifford’s reluctant to get involved, but the more he digs, the more evidence he finds. With his ability to remember everything he's ever seen, he's the perfect person to untangle the layers of deceit.

While the residents of the Québec village of Three Pines take advantage of the deep snow to ski and toboggan, to drink hot chocolate in the bistro and share meals together, the Chief Inspector finds his holiday with his family interrupted by a simple request. He’s asked to provide security for what promises to be a non-event. A visiting Professor of Statistics will be giving a lecture at the nearby university.

Could something strange be happening? After all, the murder mirrors one of Fulton’s stories about Saxford’s dark past.
