A Chief Inspector Gamache Mystery Book 12, by Louise Penny, 2016, Audiobook narrated by Robert Bathurst, released in 2016 Macmillan Audio

Gamache has come out retirement and has taken over leadership of the Sûreté academy, hoping to weed out further corruption. He makes some very questionable decisions, but he is confronted with a murder of one of the professors that he had decided to keep on rather than fire. The mystery hinges on what was going on at the academy and the involvement of three students.

The book, as other Penny books in the Three Pines series, starts slow (and continues to be slow throughout). The murder is eventually solved and there are no major twists in the plot of this one. The real enjoyment from reading her novels is to be able to follow the development and career of Gamach as well as of his friends and family.
