The novel begins in Marseilles “thirty years ago” (c. 1826), with the notorious murderer Rigaud telling his cellmate John Baptiste Cavalletto how he killed his wife. Arthur Clennam is detained in Marseilles with a group of travellers in quarantine. He meets new friends in the quarantine. He is returning to London to see his mother after 20 years in China with his father, handling that part of the family business. His father died there. On his deathbed, his father had given him a mysterious message, murmuring “Your mother,” which message and a watch Arthur mails to Mrs Clennam.

Inside the watch casing is an old silk paper with the initials DNF (do not forget) worked in beads. It is a message, but the implacable Mrs Clennam, who now uses a wheelchair, refuses to tell him what it means. The two become estranged.

In London, William Dorrit, imprisoned as a debtor, has been a resident of Marshalsea debtors’ prison for over twenty years. He has three children: Edward, Fanny and Amy. The youngest daughter, Amy, was born in the prison and is affectionately known as Little Dorrit. Their mother died when Amy was eight years old. Fanny lives outside the prison with William’s older brother, Frederick. The adult children are free to pass in and out of the prison as they please. Little Dorrit, devoted to her father, supports them both through her sewing. To the honour of her father, who is embarrassed to acknowledge his financial position, Little Dorrit avoids mentioning her work outside the prison or his inability to leave. Mr Dorrit assumes the role of Father of the Marshalsea, and is held in great respect by its inhabitants, as if he had chosen to live there. Available in store and online.
