We stepped out from behind a tapestry and George went up to a painting of a bowl of fruit on the wall. Fred let me down and handed me back my bag, grinning as George tickled the pear of the painting. I was very confused for a moment until the fruit giggled and the picture swung outward to reveal a doorway. They were both smiling ear-to-ear as we stepped into what appeared to be a giant kitchen. And inside were hundreds of bustling house elves.
