I read this book at the height of my Scandinavian thriller period, several years ago, and while I liked all book in the series, this one was always my favourite.
When a young girl is found murdered, the investigation only leads to more suspects and motives as time goes by...
But I tried to re-imagine just what made this one better than the others, and honestly, I can't be sure. The story is decent, as are most of the others, and there's the mixture between suspense and domestic story that is just right. It is a delightfully quick read, and especially to this novel I look back with very warm feelings.
Note: I read a Dutch translation of this book
