Certainly, the authors from the cold take shape now. Following the patriarch Henning Mankell - may be the most famous - the Jo Nesbo, Arnaldur Indridason, Styg Larsson, Kristina Ohlsson, Ake Edwarson and probably others I do not even have the pleasure of knowing, have all an undeniable seductive power in the genre thriller.
I highly recommend all these authors that will make you go, I am sure, very pleasant reading time
