Showing Sun and Shadow by Åke Edwardson

From the three-time winner of the Swedish Crime Writers' Award.

A couple are found murdered in their flat in Gothenburg, their bodies symbolically arranged in a mysterious and grotesque fashion. As Winter follows the trail of clues into the cult world of the gothic, he becomes enmeshed in a riddle of nightmares, where he must untangle good from evil and sun from shadow.
