chunk: The novel begins in Marseilles "thirty years ago" (i.e., c. 1826), with the notorious murderer Rigaud telling his cell mate how he killed his wife. Arthur Clennam is returning to London to see his mother after the death of his father, with whom he had lived for twenty years in China. On his deathbed, his father had given him a mysterious watch murmuring "Your mother," which Arthur naturally assumed was intended for Mrs. Clennam, whom he and everyone else believed to be his mother.
  Inside the watch casing was an old silk paper with the initials DNF (Do Not Forget) worked into it in beads. It was a message, but when Arthur showed it to the harsh and implacable Mrs Clennam, a religious fanatic, she refused to tell him what it meant and the two become estranged.
