Book - I picked up this book on audio, because it was billed as one of the best mysteries on audio, it received starred reviews from Library Journal, BookList, and Publisher’s Weekly and received numerous awards including the Agatha. I was not disappointed by this locked room mystery. It is set in the monastery of Saint-Gilbert-Entre-les-Loupes on a remote Island in the wilderness of Quebec. No outsiders are allowed in the monastery of 24 monks who live a serene and very isolated life, but Chief Inspector Armand Gamache and Jean-Guy Beauvoir are summoned to investigate the murder of Frère Mathieu, the monastery’s renowned choirmaster and prior. The investigation is difficult as the monks in the community haven taken a vow of silence. Ironically they have become world famous for a CD of their singing Gregorian chants. Their glorious voices, raised in ancient chants whose effect on both singer and listener is so profound it is known as the beautiful mystery. The investigators soon find grim discords among the seemingly unified and peaceful brothers as they search for the motive and murderer. This is the eighth book in the Inspector Armand Gamache mysteries. I now plan on reading the entire series. This book should appeal to fans of The Name of the Rose by Umberto Eco and Murder in the Cathedral by T.S. Eliot.
