A Death in Vienna (Silva, Daniel)
Gabriel Allon hasn't been back to Vienna since his wife and child died there in a terrorist bombing. But when his mentor in the Israeli intelligence agency dispatches him to the Austrian capitol to investigate a murderous explosion at  the Wartime Claims and Inquiry Office, his presence alerts the attention of police officials who have reasons to stand in the way of his investigation. When a concentration camp survivor is killed who could link the father of Austria's next chancellor to Nazi atrocities and an ongoing coverup by the Catholic Church, Allon discovers another connection to the conspiracy, this one closer to his own past than he could ever have imagined. This is the third of Silva's   thrillers featuring Allon, the art restorer who's also a spy (The ConfessorandThe English Assassinare the first two). In an endnote, the author calls them a "completed cycle dealing with the unfinished business of the Holocaust." Allon is such a compelling hero that one hopes Silva, a skilled craftsman and a terrific story-teller, will bring him back in another series.--Jane Adams
