Mr. Noble intervenes in Francis’s attack on Adah because Adah is still recovering from her emergency C-section. His motive implies that, in the novel’s view, domestic violence is somewhat normal in mid-20th-century Nigerian culture but that Francis’s violence toward Adah goes beyond what is culturally acceptable. Mr. Noble’s claim that there is nothing wrong with contraception suggests that Francis is wrong that their landlord and neighbors would wholeheartedly take his side in the dispute—again indicating that Francis is abnormally controlling and abusive even relative to the sexist cultural norms of early-1960s Nigeria and England.
