This story takes place outside of the Chalet School itself, revolving mainly around the Maynard family, during the summer holidays. Jack Maynard is to be Head of a new Sanatorium opening on the Görnetz Platz in Switzerland and the Maynard family must move out there with him. The Chalet School is to open a branch there in the September.
Daisy Venables marries Laurence Rosomon from Plas Gwyn, Jack and Joey's home, as Madge is still in quarantine following a bout of German Measles. The wedding takes place in the church in Howells village, and the reception in the village hall next door. Primula joins the Maynards when they move out to the Görnetz Platz.
Plas Gwyn is to be partially let to Gwensi Howells' stepbrother, and Robin Humphries leaves for Toronto where, at the Feast of the Assumption, she is received as a postulant in the convent of La Sagesse.
Joey and family set off for Switzerland, breaking their journey in Paris, where they stay with Joey's old school friend Simone de Bersac. With the help of other old friends they eventually reach their new home, next door to the school, but the stress of moving tells on everyone as they strive to get settled and organised in time for Daisy to visit just before the start of the school term.
