This is an utterly fantastic book. Two narrative strands, one historic and one contemporary, are intertwined, leaving the reader intrigued as to exactly what the connection will turn out to be.
The historic strand addresses issues which must be painful to many Norwegians; specifically the involvement that some of them had in supporting the Nazis to the extent of fighting alongside them on the Russian front.
The writing in this novel is absolutely superb. There is one sequence in particular where Nesbo absolutely captivates the reader and enables him to feel the pain experienced by his central character, Harry Hole. This starts with a chapter which flits between events which are happening simultaneously, much like jump cuts in certain films. This is followed by a series of chapters consisting simply of telephone messages left by Harry. These communicate very effectively all of the pain, anguish and guilt he feels at this point lifting this novel above the run of the mill detective story.
The book has many sub-plots, but these are all handled so well that they do not detract from the narrative drive and the pace of the story is well maintained.
The two strands of the narrative come together at the end in a way which is both convincing and (at least to this reader) unexpected.
Nesbo is quite simply one of the best crime novelists on the planet and the Redbreast finds him absolutely at the top of his game. I cannot recommend this enough.
