Unbelievably The Grownup is my first read from Gillian Flynn and I did quite enjoy this dark little novella.
You may have seen this quote already but I have to include it because, well it's a legend, a quote amongst quotes. Chances are it might not stand up to the test of time but I'll never forget it and it introduces the stories protagonist and vocation.
'I quit because when you give 23,546 hand jobs over a three-year period , carpal tunnel syndrome is a very real thing.'
So she's in the process of moving from hand jobs to scam artist in the guise of a fortune-teller when she meets Susan Burke. And soon she is employed to rid Susan's house of evil spirits and step-son Miles is integral. Then it's exploration of the demon child phenomena and it did grip me as things swung from is he? To isn't he? All told this was a story that keeps you guessing, some delicious twists and the kid is pretty likable for a possible sociopath, definitely interesting with an ambiguous finale.
