This is the 13th book in the Inspector Gamache novels. It is another excellent outing by Louise Penny. I love that the characters continue to evolve throughout the entire series. This book centers on the drug trade within Canada and between Canada and the US and focuses on the theme of conscience through the use of a cobrador del franc. The frame of the book is hung around Gamache's testimony in the court case of the defendant accused of killing a woman in the basement of the church in Three Pines.
