Let's say it's the first paragraph of a book. Should it be written with definite articles:

The gun pointed to his brow; Mark stood silently looking at the table and the thickly carved turkey.

Or with indefinite articles(?):

A gun pointed to his brow; Mark stood silently looking at a table and a thickly carved turkey.

The logic behind the latter is that the reader doesn't yet know what: gun, table or turkey it is exactly.

Here's the first sentence from King's The Gunslinger

"The man in black fled across the desert, and the gunslinger followed."

But the reader doesn't know which man in black, which gunslinger or desert.

How does such narration differ from what we, learners are taught. Which is, if it wasn't previously mentioned you'd use indefinite article.
