In Edgar-finalist Lutz's entertaining fourth and final novel about the eccentric Spellman PI clan (after Revenge of the Spellmans
), Isabel “Izzy” Spellman juggles the usual family drama—her mother tries to sabotage Izzy's relationship with her Irish bartender boyfriend and younger sister Rae throws herself into freeing a wrongly convicted man—while helping to drum up business in a dreary economy. While Rae works on her “Free Schmidt” campaign, Izzy investigates the whereabouts of a missing valet with a checkered past and sifts through garbage for a screenwriter client. Older brother David, the only Spellman not involved in the family business, grows closer to his defense attorney girlfriend. On the sly, Izzy is also tailing Rick Harkey, a rival San Francisco PI, and discovers that Harkey left behind a trail of suspicious arrests and conveniently misplaced evidence in his career as a cop. Narrator Izzy's biting wit—mixed with a refreshing dose of humility and sadness—easily carries the story. (Mar.)
