I think you are refering to the second chapter of this excellent book, because the book actually starts in media res, or in the middle of things, and then cuts to the beginning in the second chapter. This chapter introduces a very important character and her central conflict. April Hall has been sent to live with her grandmother by her mother, however April deeply resents this and feels that this is just a temporary arrangement, and that her mother will send for her very soon. Note how this second chapter introduces the scenario:
Exactly one month before the Egypt Game began in the Professor's backyard she had come, very reluctantly, to live in teh shabby splendour of an old California-Spanish apartment house called the Casa Rosada. She came because she had been sent away by Dorothea, her beautiful and glamorous mother, to live with a grandmother she hardly knew, and who wore her grey hair in a bun on the back of her head.
April's conflict thus lies in the way that she has been effectively sent away by her mother to live with a stranger. She refuses to settle down in this place, as this would signal that she recognises her mother is highly unlikely to send for her and ask her to come and live with her again.
The conflict in the story is that everyone is scared of the Professor because he is kind of frightening and even the bravest bullies dare to tease the old man but they fail. So before April Hall arrives there was something going on at the Professors backyard. She says that her mother will never let her live with her again.
