A little girl pointed at her and jumped up and down, "Look, Mummy, it’s Hermione Granger!" Witches and wizards were turning toward her, gawking. She ran around the corner of the nearest tent and dug out a cloak that looked like an inky night speckled with stars. She threw it over herself and crouched into a ball.  She lay there quiet and unmoving as a small woman, dressed in green tweed robes with a toady face marched between the tents, "Homenum revelio." She sniffed when nothing happened.
