Chief Inspector Armand Gamache returns to the village of Three Pines in a layered mystery that links a present-day arrival to a murder from decades earlier. As spring thaws the village, two people connected to an old tragedy reappear, stirring memories and unease for the investigators who first worked the case.

A 160-year-old letter written by a stone mason and the discovery of a bricked-up attic room set off a chain of revelations. Removing the bricks uncovers a collection of strange objects, hidden messages and clues that suggest revenge and calculated malice. Gamache and Jean-Guy Beauvoir must piece together puzzles within puzzles to understand who is back — and why.

Blending atmospheric setting with procedural insight, the novel examines memory, grief and how buried secrets shape a community. Ideal for readers who enjoy thoughtful detective fiction with moral complexity and strong character work.
