By Camilla Grebe. I read the English translation.
Clearly this was translated by an English English person, because an American English translator wouldn’t use ‘knickers’ for underwear. If you don’t mind that little bit of jarring language difference (I sure don’t), it’s a good book. Psychologically, very interesting. Recommended!

I might download a sample! I’ve been stuck on the series by Hjorth & Rosenfeldt, but their next one isn’t on Amazon till June. Excellent writers!
Thank you for the recommendation!
