The Darkness Knows

The Darkness Knows is a prime example of how to write Icelandic Noir.
An unsolved case that has long troubled Inspector Konrad is reopened when the body of a missing man is discovered in the melting ice of a glacier. The death was not accidental. Thirty years have passed since the disappearance, and Konrad has never completely stepped away from the case. Now retired, Konrad begins an unofficial investigation. Former friends and associates of the deceased are interviewed. Old memories come to the surface. Forgotten conversations are recalled.
This was a thoroughly enjoyable book. The resolution was not expected, and I wholeheartedly recommend it.
