And angelic voice murder countries in the land of fire and ice

Thrillers A. Indridason are unique as the part of the human being is as important as the story itself. This one is no exception to this rule. Indeed are not looking for serial killers or other psychopaths, but people like you and me with their flaws linked to their sometimes troubled past. Note that this is also true for suspects (or killers) and for police forces. In short novel (and author) must read.
Good reading.
