“With enormous empathy for the troubled human soul--and an ending that makes your blood race and your heart break--Penny continues to raise the bar of her splendid series.” —People Magazine (4 out 4 stars)

“Louise Penny has crafted an almost perfect crime—haunting, puzzling, brilliant and indeed a most beautiful mystery. Chief Inspector Gamache is one of my favorite characters in fiction. Here he must penetrate a cloistered monastery deep in the northern woods of Quebec, where a murdered monk is his ticket to get in. This is a tour-de-force for Penny, and a thrilling, intelligent read.” —Linda Fairstein

“A. Ma. Zing!  A remarkably courageous—and very beautiful—book that leaps the abyss between faith and despair.” —Diana Gabaldon

“Elliptical and often oracular… also remarkably penetrating and humane. The most illuminating analogies are not to other contemporary detective fiction but to The Name of the Rose and Murder in the Cathedral.” —Kirkus Reviews

“An entire mystery novel centering on Gregorian chants (whose curiously hypnotic allure is called the "beautiful mystery")? Yes, indeed, and in the hands of the masterful Penny, the topic proves every bit as able to transfix readers as the chants do their listeners.” —Booklist (starred review)

“Elegant… This heart-rending tale is a marvelous addition to Penny's acclaimed series. Fans won't be disappointed.” —Library Journal (starred review)

“Traditional mystery fans can look forward to a captivating whodunit plot, a clever fair-play clue concealed in plain view, and the deft use of humor to lighten the story's dark patches. On a deeper level, the crime provides a means for Penny's unusually empathic, all-too-fallible lead to unearth truths about human passions and weaknesses while avoiding simple answers.” —Publishers Weekly (starred review)
