From the time they were little girls Camilla had been outgoing, popular, and successful at school, while Lisbeth had been ungiving and introverted, rarely responding to the teachers’ questions. Camilla’s grades were very good; Lisbeth’s never were. Already in elementary school Camilla had distanced herself from her sister to the point that she would not even take the same route to school that Lisbeth took. Teachers and friends noticed that the two girls never had anything to do with each other, never sat next to each other. From the age of eight they had been in separate classes.
