For me this is a very very powerful book. First of all considered as a straight forward thriller I would give it my maximum mark. The quality of the writing and ther book's structure, could hardly be improved upon and I'm not surprised it took two authors with proven skills a couple of years to produce.Incidentally the translation into English also rates a maximum mark, as good as I've ever experienced. Its a thriller because being British I was unaware of the eventual outcome, and had found it gripping enough (as did other reviewers) to be rooting for both the police (especially the fictional prime investigator , John Broncks ) and for the criminals. Just read as a crime thriller i would give it 5 stars.
In addition as a parallel story of domestic abuse and its effects on the victims I would also give this novel five stars. The fact that one of the authors was a witness to much of the abuse that took place gives what happens a chilling reality that a purely fictional accoumt would struggle to replicate. I'm a pretty hardened old bastard who had a fairly rough childhood but at times I just had to stop reading for a while. These two strands of criminality and abuse are almost perfectly woven together as a story of human relationships that for me at least approaches perfection and is totally convincing. Obviously this would not be true were the dialog between characters not also spot on and totally convincing. In a novel ,unlike acted drama , the characters thoughts are revealed and also have to be totally convincing, along with the spoken dialog. In my opinion this was also pretty near perfect.
And then most staggering of all, its largely a true story. In fact I suspect that what is written in the book could be more true than what actually happened, and where it isn't it sheds additional light on domestic abuse and human relationships especially within families.
I see some fool has given the book one star and the comment"....boring...". Never rely on anyone's review--it could be written by this fool.
