I never thought I would ever get into Norwegian crime novels until I read The Lion's Mouth by Anne Holt, which is part of her Hanne Wilhelmsen Series that was first published in 1997. Personally I love novels sans smart phones, they are a real treat.
When the prime minister of Norway is found shot in the head, Hanne Wilhelmsen, Chief Inspector of the Norwegian Police must travel back from her leave in California to solve such a shocking crime. And it turns out, more shocking than the crime is the past of the prime minister that starts unraveling once Hanne begins digging.
I love the format of this novel. It's very SVU. Dates, times, locations are documented, which definitely helps readers follow along.
