In the story "Dusk," Gortsby was out witted by a young man who claimed to have lost a bar of soap. Gortsby is sitting in the park when an older gentleman sits down. Gortsby who is a good judge of character imagines that the older gentleman gets no respect at home. Gortsby values his own sense of judging another person's character.
The older gentleman leaves. A younger man sits down. The young man begins sharing his story of how he has lost his way back to his hotel. He had only gone out to buy a bar of soap. Now, he cannot seem to find his way back.
Gortsby would have believed the younger man's story if he could have provided a bar a soap. The young man realized that his scam would not be believed by Gortsby. The young man leaves the park bench, feeling defeated.
Gortsby then finds a bar of soap under the park bench. Gortsby chases after the young man and gives him the bar of soap and loans him money so he will not have to sleep out doors tonight.
Feeling good about his deed in helping the young man out, Gortsby walks past the park bench and sees the older gentleman looking for something:
As Gortsby walks back, he passes the bench where he had been sitting. He notices the old man who had also been sitting there earlier. The old man is now searching for something. When Gortsby asks if the old man has lost anything, the man replies, “Yes, sir, a cake of soap.”
This is when Gortsby feels out witted by the young man's story. He loaned him money that he will never see again.
