Further news from Penelope states that the Rachel has been amusing herself in London, under the doctor's orders. Godfrey Ablewhite has visited often, and Rachel receives him happily. Penelope mentions Miss Clack in a letter, and Betteredge introduces her as the next narrator, warning us not to believe anything derogatory Miss Clack might say of himself.
The last news Betteredge has is a London newspaper sent by Cuff mentioning that the London moneylender of whom Cuff had warned Betteredge had reported being followed and bothered by several Indians. Thus Cuff's three predictions from Chapter XXII have come true.
Betteredge asks our forgiveness for the faults of his informal narrative and leaves the reader with a quotation from his personal bible, Robinson Crusoe.
Though Cuff has failed in his general assignment of finding the thief of the diamond (and, in fact, suspects the wrong person), he still remains a prophetic character. In these chapters we see Cuff make three predictions to Betteredge, all of which come true in the span of a week, though for different reasons from the reasons Cuff supposes (as we will see). These are the only further clues in the final chapters of Betteredge's narrative. Plot movement slows down here from the rapid pace of the middle chapters of Betteredge's narrative. Strangely, all two hundred or so pages of the narrative mainly cover the events of slightly more than a week: the Wednesday of Rachel's birthday through the following Sunday, on which Betteredge receives the last of his news from London.
In the final pages of Betteredge's narrative, the plot movement has proceeded to London and left him behind at the Verinder household. As with all of the narratives in The Moonstone, supplementary information comes from documents included within the narration—here Betteredge receives information about London events from letters from Penelope and others. Betteredge explains that we must follow the "devil's dance of the Indian Diamond" to London, leaving him behind in "the country-house," and reluctantly introduces the next narrator, Miss Clack. He also admits that he knows more of the mystery than he can tell us at this time. This commentary reminds us of the non-immediacy of Betteredge's narrative (he is writing of these events more than a year after their actual occurrence), as well as the larger editorial structure within which the narratives are contained.
Betteredge's narrative closes with a quotation from Robinson Crusoe by Daniel Defoe. Betteredge has associated himself with this novel throughout his narrative—he treats it as a cure-all and as a prophetic book similar to the Bible. He explained in Chapter I: "such a book as Robinson Crusoe never was written, and never will be written again. I have tried that book for years—generally in combination with a pipe of tobacco—and I have found it my friend in need in all the necessities of this mortal life." Robinson Crusoe, written by Defoe in the eighteenth century, was still an extremely popular book in Collins's time. Betteredge flips back and forth through it, happening upon singular phrases that he takes as miniature predictions, in much the same way that some used bibles. The setting of Robinson Crusoe highlights its connection to early English imperialism, much the same way that the tobacco Betteredge smokes while reading it relates to English tobacco crops in colonies. These themes of imperialism relate back to the history of the Moonstone's theft by John Herncastle, in the beginnings of English domination over India. Thus Betteredge's love for Robinson Crusoe and the tobacco that accompanies it can be read as another subtext gesturing critically toward the history of English imperial domination over other cultures and over the products and people of those cultures.
