Sister – Kjell Ola Dahl (2018)

Suspended from duty, Detective Frølich is working as a private investigator, when his girlfriend’s colleague asks for his help with a female asylum seeker, who the authorities are about to deport. She claims to have a sister in Norway, and fears that returning to her home country will mean instant death. Frølich quickly discovers the whereabouts of the young woman’s sister, but things become increasingly complex when she denies having a sibling, and Frølich is threatened off the case by the police. As the body count rises, it becomes clear that the answers lie in an old investigation, and the mysterious sister, who is now on the run. A dark, chilling and up-to-the-minute Nordic Noir thriller, Sister is also a tense and well-plotted murder mystery with a moving tragedy at its heart, cementing Kjell Ola Dahl as one of the greatest crime writers of our generation.
