Peggotty takes David to Yarmouth, where her family live in a boat which they had converted into a home. Peggotty’s brother, Mr. Daniel Peggotty, adopted his nephew, Ham, and his niece, Little Em’ly, who are not siblings, when their fathers drowned. Mrs. Gummidge, the widowed wife of Mr. Peggotty’s brother, lives with them too.

David has a lovely time on holiday and quite forgets about his mother back at home. When he arrives, Peggotty tells him that his mother married Mr. Murdstone while they were away. David is reunited with his mother. Mr. Murdstone orders David’s mother to control herself in her behavior toward her son. David sees Mr. Murdstone again, for the first time as his mother’s husband. David thinks that Mr. Murdsone, with his great black beard, looks like an enormous and threatening dog.
