A pretty dark police procedural. Twisty plot with a whole series of interlocking crimes (there is a fairly high body count) and fairly graphic, though there is not either villain POV or abducted child POV, thankfully. It is always freezing, windy, raining or snowing in MacBride's Aberdeen (not that this isn't accurate, it just adds to the grimness of the world he creates). What saves it from being unrelentingly grim are the fundamentally decent DS Logan McRae and WPC Jackie Watson, and the humor in the relationships between some of the police. It's nice not to have a totally gloomy, self-destructive detective in a book of this kind. I will read more, but please let there be something besides the serial-killer-preying-on-children story. I am so tired of that.
