I was put on a path to Scandinavian crime literature by
The Girl Who Kicked the Hornet’s Nest, The Girl Who Played with Fire, and The Girl with the Dragon Tattoo by Stieg Larsson (Swedish). I have to tell you, the writing is mediocre to bad at times. So what kept me reading? First, the story, the plot, and second, Lisabeth Salander, the main character of the trilogy.
The Snowman and Nemesis by Jo Nesbo (Norwegian). Fabulous. Harry Hole is a classic — alcoholic, demon-ridden, heavy smoker, and brilliant. Good writing with psychological depth.
