In the heart of Dalarna’s shadowy forests, the mind can be the most dangerous place of all.

Sweden’s most notorious clinic for forensic psychiatry Säter is hidden deep among the pines — a place where the country's most violent offenders are sent when prison isn’t an option. For young psychologist Anna Varga, a position at the prestigious institution is the opportunity of a lifetime: a fresh start, a career breakthrough, an escape from her past in Stockholm.

But behind the clinic’s cold walls, something is terribly wrong.

Patients whisper about Room 55. Anonymous notes appear with chilling warnings. And when a man is found dead under suspicious circumstances, Anna’s dream job spirals into a waking nightmare. Is someone watching her? Manipulating her? And what buried truths is the clinic so desperate to keep hidden?

A twisty, heart-pounding Scandi-noir thriller perfect for fans of Gillian Flynn's "Sharp Objects", Karin Fossum and Lars Kepler.

Helena Kubicek-Boye is a psychologist and author. She used her experience in a psychiatric ward as inspiration for the Säter Clinic Thriller series, which is celebrated in her home country as "Sweden's Twin Peaks".
