"Arctic Chill" is about the stabbing or a bi-racial boy in Iceland (he's part Icelandic, part Thai). The police can't immediately find a motive. Was it racists? Was it drug dealers targeting the estate? Was it someone who was targeting the murdered boy's brother? The police try to look at all these possibilities before finally working out who the killer is.
The book isn't bad, I certainly learned something about Iceland by reading this book. The problem is that there isn't much description of the inner lives of the detectives. Even the lead detective doesn't seem that 3-dimensional if you ask me.
In addition, the book seemed to suggest (to me at least) that I had nothing to fear from Icelandic coppers. Their whole investigation smacked of chaos and inadequate forward planning. They jumped from one theory to another, without anyone getting the feeling that they knew what they were doing.
The book is short and could have done with more flow between ideas.
