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 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.

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 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.
