At Grandma Nickel's in the countryside, Karlchen spends the best holidays. There, he can play with cousin Käthe and help Grandma Nickel bake delicious carrot cake. For that, he goes to the garden to fetch the carrots. But sometimes something gets in his way, and he suddenly seems to disappear without a trace. This is the third of the Karlchen books, which bring joy not only to children.
