What is the point of view used in "The Ambitious Guest"?
The story is told from a third person omniscient point of view. Readers are told what happens, but also what is happening in each person's mind and heart, and even invited to reflect on the meaning of it all. This can be seen in passages like this: "Woe for the high-souled youth, with his dream of Earthly Immortality! His name and person utterly unknown; his history, his way of life, his plans, a mystery never to be solved, his death and his existence equally a doubt! Whose was the agony of that death moment?"
Even the soul of the "youth" is commented on, as is his fate.
