‘Have you come back?’ said the woman. ‘I thought that no one had come back.’ Does this statement give some clue about the story? If yes, what is it?

Yes, the above said statement in question gives us a clue about the story. It clearly proves that the lady, whom the young girl had paid a visit, knew her already and didn’t want to meet her. The given statement shows that the two families knew each other. Some people had left their homes due to the war many years ago. Those who had stayed back, thought that the ones who had left would never come back. That is why the woman feels surprised to see one of them come back.
