How does the author use ambiguity in the story, The Wives of the Dead?

Ambiguity is a literary device, often a word or phrase signifying multiple meanings. Poets and fiction writers use it to create possibility and mystery. The ambiguity of Hawthorne's story rests on the final sentence and the meaning of the words "her" and "she." Depending on which woman the pronoun refers to determines, in large part, what part of Hawthorne's story can be read as a dream.
