Donna Leons mastery of plot, her understanding of Venetian manners and mores, and above all her philosophical, unfailingly decent protagonist have made the Commissario Brunetti mysteries bestsellers around the world, including an ever-growing American audience. In "The Death of Faith," Brunetti comes to the aid of a young nursing sister who is leaving her convent following the unexpected death of five patients. At first Brunettis inquiries reveal nothing amiss, and he wonders whether the nun is simply creating a smoke screen to justify abandoning her vocation. But perhaps she has stumbled onto something very real and very sinistersomething that puts her life in imminent danger.
