There is a children’s picture book about a little boy sent to visit his aunt, whom he is told has many wonderful old things. It looks like it will be tedious, but a bearskin rug comes to life as a kind of floppy bear, and then they are attacked by the Mouse King and an army of animate bric-a-brac. Then the aunt comes and says “I suppose the bear is in tatters again,” and they spend the afternoon drinking tea and stitching the bear back together, but the Mouse King has eaten all the cookies. Does anyone know the author or title of this book?
James in the House of Aunt Prudence, 1993, by Timothy Bush!
