This eight part Danish crime drama is centred on Jan Michelsen, a detective, and Louise Bergstein, a profiler. He has been working on the case of a missing woman, although after six months most people assume she is dead. Then a second woman of similar appearance vanishes. Desperate to solve the case he brings Louise in to help. Her profile leads to another, older, missing person's case... and the body from that case. While we observe their investigation we also see what is happening to the kidnapped woman and learn that she actually has two captors.
When I saw this advertised I wondered if it was a remake or a sequel to the earlier 'Those Who Kill', from 2011... in fact it is neither. It is thematically linked by the detective/profiler pairing, although the genders were the other way round in the previous series. Early on one might expect this to be a whodunit but we learn that very quickly; that doesn't make it any less interesting; it is an impressive psychological thriller that isn't afraid to use horror tropes as we are shown how the victims are treated. There is a real sense of danger both for the victims and our investigators. Kenneth M. Christensen and Natalie Madueño impress as Jan and Louise but it is Signe Egholm Olsen who stands out as Stine Velin, one of the kidnappers who despite outward appearances seems to be the more frightening of the two. The rest of the cast are solid too. Overall I'd certainly recommend this to fans of Nordic crime thrillers.
