Nana Sahib
The book takes place in the aftermath of the Indian Rebellion of 1857 against British rule, with the passions and traumas aroused still very much alive among Indians and British alike. An alternate title by which the book was known - "The End of Nana Sahib" - refers to the appearance in the book of the historical figure—rebel leader Nana Sahib—who disappeared after the crushing of the rebellion, his ultimate fate unknown. Verne offers a fictional explanation to his disappearance.
