Jo Bettany is sixteen
Madge Bettany, now Russell, is happily settled on the Sonnalpe with Dr Jem and baby David
Also at the Sonnalpe are Stacie Benson, making a gradual recovery, and the Robin, her health a continual worry after the long hours of worry at Fulpmes earlier in the year
Juliet Carrick is now in her final year at the Royal Holloway and preparing to return to the Tyrol as the headmistress of the new Chalet School Annexe.
The Robin is tried and tested in every possible way, but at the end of a long and very difficult week Miss Annersley breaks the news to a distraught Joey that there is every reason to hope for good news.
The prank pulled in Oberammergau is one of the most outrageous ever perpetrated by the middles; outdoing one another with hair raising stories leads to the idea of acting out one of those stories, and, to the credit of the five, they are horrified when the excitement wears off and they realise what they have done.
Meanwhile, Juliet's background and the appalling behaviour of her father has become known to a certain young man at Holloway College. It takes Joey Bettany to set him straight, in blunt schoolgirl fashion.
The six middles who, in their final escapade of the term, shelter a runaway Biddy O'Ryan in the games shed, have no way of knowing that, as a result of their actions and the resulting interest of the school, she will go on to become one of its most popular mistresses ever.
