The Traitor





Detective William Wisting is back in this captivating, atmospheric new thriller from Norway's most successful thriller writer, Jørn Lier Horst

Following weeks of heavy rain, the earth comes sliding down on one of Larvik’s residential areas, burying a handful of houses.

Detective William Wisting is quick to join the rescue operation. Luckily, by sunrise the next day, it becomes clear that the landslide has claimed no victims.

And yet, just twenty-four hours later, a body is found – a victim who was killed before the landslide.

As Wisting opens an investigation into the mysterious murder, he soon discovers this death might have dangerous ties to a series of ongoing cases.

And the clues start leading Wisting not towards an enemy on the outside – but to a traitor in his own unit…
