The story is OK as a murder mystery. There’s an emphasis on procedure, with detailed exploration of dead-ends and alternative hypotheses. The Scandinavian theme has a certain amount of local color. Characterization is OK. The main problem is that the narration is somewhat muddy. It comes out as a sussurrating, staccato monotone that is difficult to follow, unless you are a dedicated fan paying very close attention and have a little or no environmental sounds, such as traffic, a/c, etc.. I had to stop and rewind more than once.
