The Swiss Twins centers around a Swiss family of six; a Mother, Father, older brother, the twins, and a baby sister. The Twins went away with Fritz in the early morning and stayed all day long with the goats and came home with him in the sunset glow. But on the fourth day it was quite, quite different. It was different not only because they were to go alone with the goats for the first time, but also because it was the day when the greatest event of the whole year was to happen. One in a series of stories introducing a period of history and geographical location through the adventures of twins. Here, Swiss twins, Seppi and Leneli, survive an avalanche in the mountains where their chalet is situated.
