Rosanna Spearman is introduced in Chapter IV. Collins is particularly noted for the realistic detail involved with his non-central characters. Thus, Rosanna, being a former thief with a deformity, is something of an outcast. Yet she does not exist as a mere stereotype. Her character is immediately associated with tragedy, and the potential for her character to be central or heroic is expressed in spite of her servant stature. Betteredge explains that "there was just a dash of something that wasn't like a housemaid, and that was like a lady." Rosanna seems to be the outcast counterpart to Rachel Verinder.
