In this tale of Kinsey Millhone, she celebrates her thirty-third birthday as only she can. Kinsey moves back into her renovated apartment, gets hired to find an elderly lady supposedly living in the Mojave Desert by herself, and makes the top of triggerman Tyrone Patty's hit list. As much as she hates to admit it, Kinsey realizes she's going to need help fending off a hit man and she hires a bodyguard: Robert Dietz, a Porsche-driving P.I. who takes his job very seriously. With Dietz watching her for the merest sign of her usual recklessness, Kinsey plunges into a case that will lead her into a gruesome truth about a long buried betrayal. And, in the process, will bring her face-to-face with her own mortality.
