When Armand Gamache and Three Pines bookseller Myrna Landers are named executors of a local cleaning woman’s will, they are puzzled. They meet the third executor, a young builder, when they visit the woman’s former home to meet her attorney. The deceased woman seems to have been delusional; she leaves her children a title and vast properties in Europe. But when the house later literally falls down, trapping the young builder, endangering Gamache and Beauvoir, and hiding a dead body, the mystery deepens.

Gamache is still on suspension from the Surete, and determined to find and destroy the opioids missing from his last case. An absorbing entry in this much-loved series that leaves many questions unanswered at the end.
