This is one of those books like The Slap and We Need to Talk About Kevin where no one is likeable and the outcome difficult to predict.  Here the family drama is related during a posh restaurant dinner as brothers and their wives partake of the sort of pretentious meal that the rich and famous revel in, only throughout this one there is a family crisis.  Both couples have teenage boys who have been involved in a violent crime caught on CCTV but in such a way as to make it almost impossible to identify the boys.  Their parents know who they are and now each is out to protect their own.  This is shocking, with a stunning conclusion.  A very clever book - dark, satirical and interestingly structured, made more complicated by an unreliable narrator.  Personally I could have done with less food.  Fascinating stuff.
