I've just added The Water's Edge by Karin Fossum to my database and also my amazon list of forthcoming Scandinavian crime novels in 2009. It's a new Sejer novel and is the eighth in the series which means the seventh has been skipped over.
Synopsis: Walking through the woods to Lake Linde one warm September day, Reinhardt and Kristine Ris pass a man who is in a state of agitation. Unusually in a small town, he does not return Kristine's smile and drives off in a hurry. Near the end of their walk they make a terrible discovery: lying in a cluster of trees is the lifeless body of a young boy. It is a moment that will change their lives for ever. Inspector Sejer is called to the scene, but can find no immediate cause of death. That evening he is faced with the heavy task of telling the boy's mother that her missing son has been found. As the weeks go by, the appeal for the man seen in the woods to come forward remains unanswered. A once peaceful community is deeply shaken and the children lose their freedom to walk alone and play wherever they wish. Then a second boy goes missing.
Unfortunately The Water's Edge is not published until July in the UK and August in the US.
