Madame Duval is lower-class but has married a French nobleman, seemingly so that she can join the nobility. However, although nobility was viewed as synonymous with virtue in the 18th century, Madame Duval is greedy and ambitious and does not care about Caroline, whom she tries to force into a marriage for the sake of prestige. Sir John, who is from a noble family, is also an immoral person and seduces the impressionable Caroline. This supports Burney’s point that nobility isn’t an inherent marker of goodness. Caroline’s reputation is destroyed because women of her time were expected to remain pure until marriage—by destroying the marriage license, Sir John makes it look like Caroline became pregnant out of wedlock.
