Continuity mistake: In Chapter 3, Perry describes how Hester Monk will be leaving the Portpool clinic, and says that Margaret Ballinger "knew Hester was going, but she refused to think of it." But then, in Chapter 5, Hester tells Margaret she is leaving, and "Margaret looked stunned" and asks Hester if she means she is leaving for always. Margaret should not be stunned in Chapter 5 if she already knew Hester was leaving, as indicated in Chapter 3.
