Wire in the blood. Val McDermid. 2012.

Young girls are disappearing around the country, and there is nothing to connect them to one another, let alone the killer whose charming manner hides a warped and sick mind.

Nobody gets inside the messy heads of serial killers like Dr Tony Hill. Now heading up a National Profiling Task Force, he sets his team an exercise : they are given the details of missing teenagers and asked to discover whether there is a sinister link between any of the cases. Only one officer comes up with a concrete theory - a theory that is ridiculed by the group…until one of their number is murdered and mutilated.

For Tony Hill, the murder becomes a matter of personal revenge, and joined again by colleague Carol Jordan, he embarks on a campaign of psychological terrorism - a game where hunter and hunted can all too easily be reversed.
