Inspired by a bit of (I think) Rivals, which mentions that Madge Russell came back to the school and took over her old lessons, leaving whichever mistress was free to look after David. The thought occurred to me - what if the mistress in question didn't really want to be left alone with a baby? This is Nell Wilson's story.

What might Tristan and Sarah Denny have felt on arriving in Tiernsee and coming upon the Chalet School?
