To be frankly jaime increasingly this series! First, because from the beginning we follow several characters, we sattache to them, we sidentifie are compared and the other side, investigations for the murders are really well done, original, surprising. It sounds a little book of Henning Mankell "the return of the dance teacher" because we learn a lot about the period of World War II in Sweden without it being boring or traumatic. Then technical side of the audio book, the book is brilliantly played by Eric Herson-Macarel (they washed heard in "Bird of bad omen"), so we really impression to have a sequel, so that this is not the case with very first opus! And to top it all, Audiolib editions have finally between cut-paragraphs with jingles during which enables better follow the story and not confuse sequences!
