This story in the original contains a little less than two thousand
words. It will be seen at once that unless handled in such fashion as to
appeal vividly to the imagination, a story with this for its theme will
seem weak and unreal. It must be made as suggestive as possible or it
will fail. It preaches, but it must avoid the air of preaching. Consider
carefully how you would present the stranger--whether first at the
window or before--so as to affect the reader with a sense of something
more than human in him.
