The Complaints: that's the name given to the Internal Affairs department in the Edinburgh police. They seek out dirty and compromised cops, the ones who've made deals with the devil. A major inquiry into a neighbouring police force sees Malcolm Fox and his colleagues cast adrift, unsure of territory, protocol, or who they can trust. An entire station-house looks to have been compromised, but as Fox digs deeper he finds the trail leads him back a couple of decades to the suicide of a prominent politician and activist. There are secrets buried in the past, and reputations on the line.
