The triumph of the Indians in stealing the diamond, along with their murder of Godfrey, is presented within the sphere of poetic justice. Godfrey, as a casualty, is parallel to the three Brahmins killed by John Herncastle in India in 1799. Since Godfrey is discovered to be a dishonest and evil man, his death is not much mourned among the other characters. The search for the diamond continues, but, notably, no one has truly expressed a desire for the return of the diamond—there is an almost supernatural sense that the diamond brings ill luck with it when it is outside of India.

Cuff's final report to Franklin in which he explains the background of both his own detective work—and Godfrey's criminal past—has become a common characteristic of detective fiction. It is common for the detective, after he correctly guesses and exposes the criminal, to fill in the details of the crime, as well as the method of his detection.
