Could someone tell me whether Hemingway is a reliable author in "Hills Like White Elephants" please? Would someone be able to help me with this...

I think
all authors can be considered reliable. They may sometimes use a narrator who is or is not
reliable. But in "," Hemingway is not using a fictitious narrator; he is writing in
what is called third-person omniscient. Whatever he says is reliable, although he may have left
out a great deal of information, as he liked to do in his short stories. There is a big
difference between a reliable author and a reliable narrator.
