There are two Jewish cops in all of Helsinki. One of them, Ariel Kafka, a lieutenant in the Violent Crime Unit, identifies himself as a policeman first, then a Finn, and lastly a Jew. Kafka is a religiously non-observant 40-something bachelor who is such a stubborn, dedicated policeman that he's willing to risk his career to get an answer. Murky circumstances surround his investigation of a Jewish businessman's murder. Neo-Nazi violence, intergenerational intrigue, shady loans - predictable lines of investigation lead to unpredictable culprits. But a second killing strikes closer to home, and the Finnish Security Police come knocking. The tentacles of Israeli politics and Mossad reach surprisingly far, once again wrapping Kafka in their sticky embrace.
