The Darkness by Ragnar Jonasson takes place in Iceland. The unique central character is an older woman detective more or less being forced to retire. Resurrecting a cold case involving the drowning of a young Russia immigrant woman who had been seeking asylum turns her world upside down. It’s very atmospheric and chilling in every sense of the word. There are plenty of people who do not want her to unearth the truth. She just stays one step ahead of them, which certainly keeps the pages turning.
