In this chapter, we are introduced to a new character, a young boy, who has come to live with his mother. The boy's name is Nemo, and he is the son of Nemo's first wife, who was killed during the Battle of Waterloo. Nemo has been orphaned, and his mother has been left to care for him. He has been forced to live in an abandoned part of the city, where he has no friends or family, and where he does not even know his own mother.
