It's been fifteen years since Simon Meier walked out of his house, never to be seen again.

And just one day since politician Bernard Clausen was found dead at his cabin on the Norwegian coast.

When Chief Inspector William Wisting is asked to investigate he soon discovers he may have found the key to solving Meier's disappearance.

But doing so means he must work with an old adversary to piece together what really happened all those years ago.

It's a puzzle that leads them into a dark underworld on the trail of Clausen's interests and vices . A shady place from which may never emerge - especially when he finds it leads closer to home than he ever could have imagined.
