Vals Spel (Lucas Davenport, #12)

When a spring thaw disinters the body of a young woman who's been missing for over a year, Minneapolis detective Lucas Davenport doesn't have much to go on except the victim's rumored connection with an unnamed man, who may be an artist and also, perhaps, a priest. But then the deserted property where her body was discovered turns out to be a killing field full of other young blondes last seen in the company of a man with a nasty habit of superimposing their faces on pornographic drawings. Davenport begins to close in on a serial killer whose perverted hobby provides the clues Davenport needs to stop him in his bloody tracks. James Qatar isn't a priest, and he's not really an artist, but he's definitely a monster, one who's met his match in Davenport.

Davenport is a smart, thoughtful cop whose girlfriend is pressuring him to make a commitment to parenthood and whose boss is about to lose her job in a political turnover. While the search for the killer is handled in author John Sandford's usual, crisp, procedural style, it almost seems to be a pretext for exploring the evolution of Davenport's relationship with Dr. Weather Karkinnen.
