How does the author use foreshadowing in An Astrologer's Day?

The astrologer's appearance serves as an indication of what kind of person he is. The abnormal light in his eyes, which his customers take to be prophetic, is nothing more than the gleam of a man in search of his next sale. Further, the ambiguity with which the author describes the astrologer's quick departure from his village, that he had to leave without a word to anyone, will serve as foreshadowing that there is more to the tale than the reader knows at that moment.
