Thus begins An Accidental Murder, the latest book in Robert Rosenberg's acclaimed Avram Cohen mystery series. In a tale that takes the retired Jerusalem detective from Germany's Frankfurt book fair to the Negev desert, as he searches for a murderer in Germany and ends up in the dark netherworld of the new Russian mafia in Israel, Avram Cohen is revealed as never before -- a man with a complex past that makes his future most uncertain.

Someone wants to kill Cohen -- or so it seems -- possibly because of something he wrote in his memoir about his year as an avenger assassinating Nazis after his long-ago liberation from the Dachau concentration camp. But then his longtime protege Nissim Levy is found murdered on the road to Eilat.

Is this a revenge killing somehow aimed at Cohen, or as Nissim's former assistant believes, could the Russian mafioso be involved?

From private nightclubs where mafia kingpins entertain with vodka-drenched feasts to massage parlors where the women work with cold-blooded professionalism, Cohen's search for Levy's killer becomes a twisted journey into a new side of Israel hardly known to the outsider. On the way, Cohen must look back at his own guilt before he can unveil a killer with a misguided but nonetheless profound motive for murder.

This finely drawn novel is, like all the Cohen novels, a portrait of a deeply complicated man trying hard to be moral in a world where greed rules. Building an atmosphere of personal pain and paranoia up until the very last pages of the book, Rosenberg gives us a tour de force.
