Summary: Gamache, now head of the Sûreté du Québec gambles.
The Chief Inspector Gamache series has been consistently the best mystery series I have read. It is rare series, 13 books in, that still keeps me engaged. And I think the last two books, while a bit unbelievable as mysteries, are probably the best two books of the series.
Armond Gamache has been a career homicide detective. The past several books he has been in an out of the Sûreté. Two books ago he took down the corrupt head of the Sûreté. The last book he was the head of the training academy where he again rooted out corruption. Now he is the head of the whole Sûreté and he turns his attention to the drug trade.
What I have loved about the series is the characters. I am not particularly interesting in the actual mysteries except as a means to see the characters. Penny falls into the common mystery series trap of thinking that she needs to make each successive crime bigger to keep the attention of the reader. (I think this is a false trap. Crimes do not need to be bigger, but the growth of the characters needs to be bigger.)
While I am not particularly interested massive governmental corruption or international terrorism plots or organized crime, I am interested in how those challenges impact Gamache. One of his faults is keeping the responsibility and information too close to his vest. This is a book where he is forced to plan with others a little bit. But because of previous corruption he keeps that circle very small.
