The fifth installment in the New York Times bestselling series by Lisa Lutz, featuring the fearless private investigator Izzy Spellman and her quirky, yet endearing, family of sleuths.  Isabel Spellman, PI, might be the most normal member of her family. Mom has taken on an outrageous assortment of extracurricular activities.  Dad has a secret. Izzy's brother and sister are at war.  And her niece keeps saying "banana" even though she hates bananas.  That's not to say that Izzy isn't without her own troubles. Her boyfriend, Henry Stone, keeps wanting "to talk,".  Things aren't any simpler on the business side of Spellman Investigations. First, Rae is hired to follow a girl, only to fake the surveillance reports. Then a math professor hires Izzy to watch his immaculate apartment while he unravels like a bad formula. And as the questions pile up, Izzy won't stop hunting for the answers—even when they threaten to shatter both the business and the family.
