The young man has no soap to prove to Norman that his story is legit and forces Norman and the readers to believe that the young man was simply trying to scam Norman out of money. While researching Saki and some of her works, I came across an interesting fact about some of Saki's stories. Saki wrote about 135 stories and most of them have trap endings. In Dusk, after the young man leaves, Norman finds a bar of soap that immediately makes him feel guilty because it stereotypes the young man as a con artist and gives him money and goes back to the bench. This is where the old man comes in, his role in the story makes the reader reconsider the entire story, the twist giving the story a hanging ending feel. Norman returned to the bench and ran towards the old man looking for something. Norman asks the old man what he's looking for and he says a bar of soap. This final twist makes the story confusing because there is no way to know who owns the soap. Creates many different theories as to whether the young man made up the story when he saw the soap on the ground or whether he used the old man's story and disappeared.
