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. Everywhere Gamache turns, he sees Amelia Choquet, one of the cadets. Tattooed and pierced. Guarded and angry. Amelia is more likely to be found on the other side of a police line-up. And yet she is in the academy. A protégée of the murdered professor....

On a quiet August morning, Judge Deborah Knott's father Kezzie makes a shocking discovery on a remote corner of his farm: the body of a man bludgeoned to death. Investigating this crime, Deborah's husband, Sheriff's Deputy Dwight Bryant, soon uncovers a long-simmering hostility between Kezzie and the slain man over a land dispute. The local newspaper implies that Deborah's family may have had something to do with the murder-and that Dwight is dragging his feet on the case. Meanwhile, Deborah is given a cigarette lighter that once belonged to her mother. The cryptic inscription inside rekindles Deborah's curiosity about her parents' past, and how they met. For years she has wondered how the daughter of a wealthy attorney could have married a widowed, semi-illiterate bootlegger, and this time she's determined to find the answer. But why are Deborah's brothers so reluctant to talk about the dead man? Is the murder linked to Kezzie's illegal whiskey business? And could his courtship of Deborah's mother have something to do with the bad blood between the two families? Despite Deborah's promise not to interfere in Dwight's work, she cannot stop herself from doing everything she can to help clear her brothers and her father from suspicion.
