But then she meets Susan Burke.Susan moved to the city one year ago with her husband and 15-year-old stepson Miles. They live in a Victorian house called Carterhook Manor. Susan has become convinced that some malevolent spirit is inhabiting their home. The young woman doesn't believe in exorcism or the supernatural. However when she enters the house for the first time, she begins to feel it too, as if the very house is watching her, waiting, biding its time . . .The Grownup, which originally appeared as 'What Do You Do?' in George R. R. Martin's Rogues anthology, proves once again that Gillian Flynn is one of the world's most original and skilled voices in fiction.
