The name of Maria Griepe is no less known in Sweden than the name of Astrid Lindgren. Her books for children and teenagers are a fascinating mixture of a sharp plot, subtle psychologism and a light touch of mysticism. The book offered to the reader is a clear confirmation of this. Sweden, the beginning of the last century, a new maid Caroline comes to the house of Bertha, Roland and Nadya, who is very different from her predecessors. She is smart, charming, very capricious, and besides, there is undoubtedly some kind of mystery surrounding her... In the story of the famous Swedish writer about the complex relationship between two teenage girls, an almost detective plot and a slick psychological drama are surprisingly harmoniously intertwined.
