Two corpses have been found. One on the riverbank and the other in an isolated farmhouse. They have been savagely beaten and the skin flayed from their bodies with their throats slit. On both victims the DNA of Charlie Pope, a convicted sex offender, has been found, and now all Davenport has to do is find him. But something doesn't sit well with Davenport because the killings appear to be calculated and methodical, and Pope is of low mental intelligence. He is incapable of the forethought and planning that these killings would have required. However, all the evidence points right at Pope - but Davenport isn't convinced of his guilt, and to find the answers he needs to locate Pope, and to do this he will need the help of three vicious serial killers who are as cunning as they are deranged...
