I love this moment in China Miéville's The City & the City: The narrator (for this is an I-book), Inspector Tyador Borlu, is a noir cop in a fictional Balkan capital, Corwi is his assistant, and in their language aj Tyrko means Turkish-style.
At the end of a work of fiction, the ideal reader knows as much as the author. How could it be otherwise? There is nothing else to know.This means that the end of the work is the end of omniscience.
