The Spellman Files [EPUB ebook] 

‘Fast-paced, irreverent, and very funny,  The Spellman Files is like Harriet the Spy for grown-ups’ Curtis Sittenfeld, author of Eligible and American Wife
Izzy Spellman is 28, single and works for Spellman Investigations, a family-run private detective agency. She might have a chequered past littered with romantic mistakes — but at least she’s good at her job. Invading people’s privacy comes naturally. To the whole family. To be a Spellman is to snoop on a Spellman; tail a Spellman; dig up dirt on, blackmail and wire-tap a Spellman.
But when Izzy’s parents hire her 14-year-old sister to discover the identity of her new boyfriend, Izzy decides she wants out. Before they’ll let her go, her parents ask her to solve one last case — a 15-year-old, ice-cold, missing person, impossible-to-solve case. But when a disappearance occurs far closer to home, Izzy’s Impossible Case becomes the most important of her life.
‘Hilarious. My enjoyment of The Spellman Files was only slightly undercut by my irritation that I hadn’t written it myself. The funniest book I’ve read in years!’ Lauren Weisberger, author of The Devil Wears Prada
‘The Spellman Files is hilarious, outrageous, and hip. Izzy Spellman, P.I., is a total original, with a voice so fresh and real, you want more, more, more. At long last, we know what Nancy Drew would have been like had she come from a family of lovable crackpots. Lisa Lutz has created a delicious comedy with skill and truth. I loved it’ Adriana Trigiani, author of Lucia, Lucia and Big Stone Gap
