Will he someone to save Hanna?

In making his morning jog, the inspector Petra Westman discovers a baby from hypothermia in a bush. In a sand container, the lifeless body of a young woman could be his mother.
This is the team of Commissioner Conny Sjöberg is responsible to clarify this matter. At the same time, he must find the murderer of a girl strangled in the bathroom of a ferry.
Meanwhile, little Hanna is home alone and nobody knows.
I stayed glued to the breathless thriller, not content to follow us two exciting investigations, we also attaches to the members of the police Hammarby. Conny Sjöberg protects his team. He himself, however, is not foolproof: the victim of a recurring nightmare, he feels terribly attracted by a flaming red. The daughter of his friend Jens, slightly handicapped, is manipulated by an unscrupulous man. Petra suspected members of his entourage to have abused her.
The stories intersect, intersect, overlap. Carin Gerhardsen, in good mathematician, built his intrigues with rigorous logic and built his series as a huge chess.
I can only advise you that taking this thriller loose only once reached the last line.
