The Kingdom by Jo Nesbo

In the mountains of Norway a man lives a peaceful existence. However one day his younger brother, always the more successful and charming of the two, turns up to visit, accompanied by his new wife. It soon turns out that the little brother is not quite as angelic as he seems.

Set in a small town filled with secrets, this compellingly dark new thriller from the Sunday Times number one bestseller has a plot as explosive and multi-layered as any of the Harry Hole novels.
