Broken Prey by John Sandford

BROKEN PREY opens with pervert (and possible murderer) Charlie Pope smelling rancid and miserably scratching out an existence as a garbageman, the only job that he could get since being released on parole from St. John's Security Hospital. Every time Charlie sees a good-looking woman he is reminded of the fact that he is tethered to an electronic ankle bracelet and constantly branded in the press as a danger to the community; after over eight years of incarceration Charlie is desperate enough to fulfill his physical desires by whatever manner necessary. 

The narrative then switches to an upscale Minnesota suburb as Lucas Davenport arrives at a truly horrific murder scene in the Porsche so familiar to the legions of fans of the PREY series by John Sandford. Even to law enforcement professionals involved, the details of the gruesome crime are almost stomach turning. (In fact, it threatens to be the crime which finally causes Lucas' long time associate Sloan to totally burn out and retire from the police force.) The victim is a young woman; her body was systematically scourged, after her throat cut the body was arranged by the killer so that the display would have maximum impact. The details of the killing are not released to the press, both so as to avoid alarming the public and to aid the police in their investigation. When a second victim (a older male who was killed and displayed in the same manner ) is discovered several miles away three weeks later, it is clear that there is not only a serial killer but a true sociopath at large in southern Minnesota. 

All the evidence that Lucas and his team assemble points to Charlie Pope, who has cut off his ankle bracelet and disappeared. And yet confusion and doubt linger. The crimes have been so meticulously plotted and carefully executed that Lucas wonders whether Charlie, a man of limited intellgence and supposedly subject to emotional impulse, could really have committed such acts on his own or is simply being manipulated in some manner by a clever mastermind. (Perhaps Charlie has somehow remained in contact with the "Gods Down The Hall", the three most dangerous prisoners at St. John's; they are all kept in solitary confinement due to the extreme danger which they pose to anyone with whom they come into contact). 

 This is my first John Sandford, but i will be looking out for more.

A rocketing roller-coaster of a ride, likeable characters (well, mostly) and I didn't work out who-dunnit.
