Night Prey (Lucas Davenport, #6)

Porsche-driving Lucas Davenport, who has just returned to duty after recovering from a serious gunshot wound, is charged with saving the political life of Rose Marie Roux, the ambitious police chief who has her eye on a Senate seat. He's given the assignment of tracking to ground the sex-crazed perpetrator of a series of murders of young women. Davenport's unwelcome colleague in this case is feminist Meagan Connell, an abrasive State Bureau of Criminal Apprehension investigator who's obsessed with catching the killer before she dies of cancer.

Also bedeviled by the ill-timed assignment of a new partner, a yuppie who was formerly assigned to the grade schools as "Officer Friendly" and who happens to be the husband of the mayor's niece, Davenport is additionally saddled with the mystifying death of an elderly woman who died rather conveniently, freeing some local hoods to profit from a real-estate scam.

The killer is dropping bodies all over the metropolitan area ... and makes the mistake of becoming a little too obsessed with a potential victim and thus leaves a trail that Davenport and his fellow officers finally discover.
