The landlady intentionally deceives Billy here, creating an outward appearance that makes him feel at home, when in fact he is in grave danger. Although he fears “rapacious landladies,” Billy follows his host anyway, noticing how motherly she looks. In this context, the landlady stands in as a mother figure, and seventeen-year-old Billy succumbs to his desires to be guided by a nurturing adult. Dahl seems to suggest that environments of anonymity are especially dangerous to innocents like Billy, who are so desperate for personal connection that they rely on untrustworthy people.
