So I recently finished the Joona Linna series and I loved it. The killers in it like Josef, Lydia and Nellie were genuinely disturbing. Jurek Walter was something else entirely, less a man and more a presence that is somehow very human. I've read some other crime series mostly American and British but the killers there are nothing compared to the ones in Joona Linna. It was very dark and I really loved that. I also did read the Schaffer and Kaldan series which was also pretty good.
Are there any other Nordic crime series that are psychologically dark and disturbing like Joona Linna?
