In this book, Rebus, who's wangled himself a job on Scotland's equivalent of New Tricks, accidentally (on purpose) backs himself into a multiple murder inquiry when a "Cold Case" he's working on is linked to a mass murderer stalking women of Scotland's A9 trunk road.
It wan't a bad read, it just stretched credibility on occasions when Rebus was dealing with Malcolm Fox (an Internal Affairs officer who had an unreasonably silly lock on Rebus) and certain members of the Edinburgh underworld. Overall, though it wasn't a bad read. Not the greatest book in the series, but still pretty good.
