Project Nirvana is the second part of the Walter Grohn trilogy, and the sequel to Anger Mode.

The mastermind behind several brutal murders seems to have disappeared from the face of the planet and the investigation is stalled. Detective Inspector Walter Grohn searches in vain for clues when a hostage drama suddenly leads the hunt in an unexpected direction.

Everything points to a kidnapping of the man responsible, but by whom? And for what reason? At the same time, suspicions arise about an infiltrator in the investigation. Someone inside the police headquarters seems to be doing their utmost to prevent the murderer being found.

A special task force is assembled and once again, Walter and Jonna de Brugge are working side by side, against an adversary who always seems to be one step ahead.
