Donna Leon' s critically acclaimed, internationally bestselling Commissario Guido Brunetti series has attracted readers the world over with the beauty of its setting, the humanity of its characters, and its fearlessness in exploring politics, morality, and contemporary Italian culture. In the pages of Leon' s novels, the beloved conversations of the Brunetti family have drawn on topics of art and literature, but books are at the heart of this novel in a way they never have been before. One afternoon, Commissario Guido Brunetti gets a frantic call from the director of a prestigious Venetian library. Someone has stolen pages out of several rare books. After a round of questioning, the case seems clear: the culprit must be the man who requested the volumes, an American professor from a Kansas university. The only problem— the man fled the library earlier that day, and after checking his credentials, the American professor doesn' t exist. As the investigation proceeds, the suspects multiply. And when a seemingly harmless theologian, who had spent years reading at the library turns up brutally murdered, Brunetti must question his expectations about what makes a man innocent, or guilty.
