The Sons of Norway blog recently published a post about this article from the Wall Street Journal: "The Strange Case of the Nordic Detectives." The article notes the international popularity of Scandinavian crime fiction and asks, "What's the appeal of all this blood on the snow, police boots crunching over frozen grass[,] and detectives whose every utterance comes in a puff of visible breath against a background of interminable night?"
The article is worth reading for the writer's answer to that question. Along the way, she mentions several Scandinavian authors and titles of their detective fiction so that you can head to the nearest library, bookstore, or online book source and sample the genre for yourself. Check it out!
