In this “powerful” novel in the New York Times–bestselling series, an Italian police detective delves into two deaths and a dark era of history (The Times, London).

When Commissario Guido Brunetti first meets her, Claudia Leonardo is merely one of his wife’s students. Intelligent and serious, she asks for his help in obtaining a pardon for a crime once committed by her now-dead grandfather. Brunetti thinks little of it—until Claudia is found dead.

Unable to find any living relatives, he visits the elderly Austrian woman who was once Claudia’s grandfather’s lover and with whom Claudia was close—and is stunned by the extraordinary art collection she keeps in her otherwise modest apartment. When she, too, is murdered, Brunetti’s investigation uncovers shocking skeletons in the closet of Nazi collaboration that few in Italy want revealed . . .
