The overall strategy that Toni Morrison employs is multiplicity. She conveys the complexity of the situation that the novel explores in part through the book's complicated structure. She employs multiple genres as well as multiple narrators (and types of narrators) and frames the past from the perspective of the present. Although the novel is not essentially a mystery, the gradual revealing of significant information creates a thread of suspense that runs through it.
While much of the novel is concerned with Pecola and her many problems, the reader primarily gets to know her through Claudia. As the two women are the same age and Claudia is concerned about her, the reader could infer that they were close while growing up. Instead, by using Claudia as a first-person narrator, the author shows the distance between the two girls, stemming in large part from their distinct family situations. Rather than make them polar opposites, which would reduce both to stereotypes, Morrison endows Claudia with the characteristic of curiosity and, to some extent, compassion.
In this way we are guided into understanding why Claudia is so concerned with the other woman's problems. Providing some sections that use a third-person narrator, the author allows the reader insights into situations and people that Claudia would not readily access. In addition, by using a reading primer with an all-white world, Morrison offers examples of the kind of dominant media image that appealed to Pecola and other children who grew up with unfulfillable desires and, tragically in her case, self-loathing.
