Monsieur Du Bois is Madame Duval’s French lover who escorts her to London. Monsieur Du Bois is generally polite and reserved. He does not speak much English, so his perspective is mainly lost on the other characters—only Evelina, who speaks a little French, can converse with him. The relationship between Madame Duval and Monsieur Du Bois is ambiguous, but it is implied that Monsieur Du Bois does not really have feelings for Madame Duval and is probably with her for her money. Monsieur Du Bois ends up falling in love with Evelina and confessing his love to her—thus ending his relationship with Madame Duval. Although Evelina is annoyed by Monsieur Du Bois’s conduct, he is generally an unthreatening and somewhat pathetic character.
