The Blue Hour — T. Jefferson Parker

Do you always check the backseat of your car before you get in?
You should.

Tim Hess is a semiretired veteran cop staring at a death sentence - his own. Detective Merci Rayborn, young enough to be his daughter, is brash, impatient, and not someone from whom Hess wants to be taking orders. He certainly isn't planning on falling in love with her...

Together they must track down a psychopathic killer who's been abducting beautiful young women from the malls of Orange County. Dubbed the "Purse Snatcher" for the chilling way he brags about his shockingly distinctive crimes, he is T. Jefferson Parker's most original creation yet.
