Dünnes Blut

Alexander Bischoff grew up without parents. He has never had a family, nor does he have any children. He works as a Detective Superintendent in a specialized department. It is a profession that Bischoff chose deliberately, because, he says, he wanted to be part of something good. But after twenty-five years in the job he has become disillusioned. When he is assigned a
case concerning an Arabic extended family which offers him at long last the opportunity he has been seeking, the lines between good and bad, right and wrong become very blurred.
