Question

Why does Dancy want to get to Nairobi? What is Mabel's response?

Answer 1

Dancy says that apart from the accusation made by De Levis life was a ghastly tame-cat sort of life. (life without excitement). So he thinks it would be better to go to Nairobi.
Mabel is bothered about what others would say. She says that it looks like running away and they must stay and fight it. She also questions Dancy saying that if she was accused of stealing pearls, what would he think of her, if she ran away from it.
