Highland Twins at the Chalet School
Synopsis:
Mrs Jean Mackenzie, a friend of Jo's, writes to Jo about her cousins; Archie (24), Sheina (a little younger than Jo), Hugh (late teens), Kenneth (15) and twins Flora and Fiona Macdonald (11). Their parents are dead and they live in a remote island in the Outer Hebridies called Erisay.
The Admiralty have taken over the island and they girls are going to have to go to school and Sheina expects to be called up. As they are unused to people Jean wants them to go to Jo's first. Jo instantly nicknames the twins "Flora and Fauna".
The triplets are nearly 2, Margot nearly died of bronchitis the previous winter as she was always the most fragile of them and the family are just realising that the triplets are not going to be identical after all.
Jack sailed to the East 2 months ago and will be gone for a long time.
There are nearly 150 girls at the school by this time. During the term, Miss Annersley gets a telegram from London signed by two of the peace league and believes it may be the Linders.
One twin mentions the chart of Erisay and its secret and Betty WynneDavies overhears the Junior's chattering. Sheina had given it to the twins for safe keeping. A spy overhears Betty planning to take the chart to spite the twins who had annoyed her.
Jo receives news that Jack was swept overboard and can't be found. Daisy goes to fetch Jem who has known him since he started at the San when Jo was a schoolgirl of 14. Fiona uses her second sight and believes that Jack is not dead. Jo makes the final transformation to adulthood.
