Josie Smith at the Market by Magdalen Nabb
Josie Smith is the irrespressible little girl who's been on Granada TV in several series. She's the one who's jealous of her best friend Eileen (who always gets whatever she wants). She's also the one who gets into trouble all the time, but generally seems to come up smelling of roses! In this book Josie Smith wrecks Eileen's house, is caught copying at school, and gets lost at the market but makes a new, and very special friend.
