Hidden deep in the wilderness are the cloisters of two dozen monks - men of prayer and music, famous the world over for their glorious voices. But a brutal death throws the monastery doors open to the world. And through them walks the only man who can shine light upon the dark deeds within: Chief Inspector Armand Gamache.
Who among the brothers has become an angel of death? As the peace of the monastery crumbles around him, Gamache finds clues in the divine, the human . . . and the cracks in between.
