The Story of an Hour by Kate Chopin

At the end of the story, it is made known that her husband was not involved in the railroad disaster and upon his return home Mrs. Mallard suddenly dies. The cause of her death is ambiguous and left for analysis as it can range from her known heart problems to psychological factors. We can ask ourselves if the real reason for the death was knowing that she wouldn't be free after she sees that her husband isn't really dead.
