San Francisco PI Isabel “Izzy” Spellman endures court-ordered therapy sessions as well as blackmail in Lutz's wacky crime novel, the third entry (after Curse of the Spellmans
) in a series that keeps getting better and better. Albert and Olivia Spellman, Izzy's parents, want her to return to work for the family PI firm; otherwise, they may have to sell it. While Izzy contemplates their offer, she secretly moves into her brother's guest apartment; helps her elderly lawyer friend, Mort Schilling, accept his upcoming move to Florida; and mourns the loss of her bartending job. Will she rediscover her yen for snooping when she takes on “the Case of Ernie Black's Not Terribly Suspicious Wife Who Probably Wasn't Cheating on Him”? Or say sayonara to snooping? Hyper spy girl Rae, Izzy's teenage sister (who may have cheated on her PSAT), provides dizzy distractions. Punctuating the rapid-fire plot are amusing therapy session transcripts and footnotes. (Mar.)
