“The landlady” is a story where everything is fine and normal at the beginning and then little by little it shows and gives clues in the text about what might happen to Billy.
Like what we discussed at the beginning of the meeting we had, at first, the setting was cold and gloomy and it doesn’t make you less aware of what might happen next because usually, people think that the more serious the setting, the more serious or sad the story that takes place in it.
