The story in itself is interesting and well told- better than the last instalment of the Rebus series. Rebus had mellowed in the last books and now he really is back as a complex character and not an entirely likeable one. His old problems with authority are back with a vengeance. Exit Music tells the story of Rebus' last case and his last ten days before retirement.Rankin said in interviews that he was still undecided as to whether Rebus will return or not. The ending of Exit Music is very good as it shows as a very dark side of Rebus' psyche and the true nature of his relationship with Cafferty. From my point of view this is one of Rankin's best.
