Three years ago, Detective Saga Bauer received an ominous postcard describing a gun and nine white bullets - one of which was intended for her partner, Detective Joona Linna. The sender alleged that Saga was the only person who could save him. But as time passed, the threat faded.
Until now.
A sack with a decomposing body has been found hanging from a tree in the forest. A milky white bullet casing turns up at the scene. When the body count begins to rise, the police realise that the killer is sending riddles, offering them the chance to stop the murders before they happen.
An alarm sounds in the middle of the night for a burglary in progress at a winter-closed campsite in Bredäng, outside Stockholm.
The police spot a light in one of the farthest caravans and when the officers open the door they are greeted by a horrific sight. Floors, walls and furniture are completely covered in blood. A man has been killed with an axe and brutally dismembered.
On the floor lies a young man sleeping with a severed arm as a pillow. He is arrested and taken to Kronoberg prison, identified as seventeen-year-old Hugo Sand, the son of a famous writer.
