I think I’ve read all the Swedish murder mysteries (in English) by Viveca Sten. The locale is an island east of Stockholm. In the Heat of the Moment is my least favorite of the series – one of the recurring characters Nora has too little a role, usually making breakfast or worrying. This title has 99 chapters, written for easy adaptation to TV screenplays which also have been popular in Sweden.
The lady translator uses common American idioms and I can’t tell if the Swedes really talk that way.
This particular book is about teenagers so there’s vulgarity that I didn’t notice in the other novels.
As her novels unfold, the reader can tell that there’s one or two critical witnesses or characters who the cops can’t quite get to until the end, and then the murder is solved. So, there’s a lot of drivel dialog and throw-away actions. In this novel, I think there’s also two characters who sleep through most of the story.
