Detective Inspector Joona Linna has been called to a home for troubled girls, north of Stockholm. A young girl has been brutally murdered, her body arranged in bed with her hands covering her eyes. Vicky Bennet is the only girl unaccounted for. Did she run away to escape the chaos or does a bloody hammer found under her pillow make her the prime suspect? As Joona refuses to accept the easy answers, his search leads him into darker, more violent territory, and, finally, to a shocking confrontation with his past.
