In chapter II of Part II of Camus's novel The Stranger, Meursault narrates a story that he read in an old newspaper cutting that he found under his mattress in prison. Below is a summary.
A man from a Czech village makes a fortune abroad and returns to his village twenty-five years later. He leaves his wife and daughter in a hotel and then checks into the hotel run by his mother and sister (to surprise them), who don't recognise him. During the night, they kill him for his money. The next morning, the man's wife and daughter arrive at the hotel and unintentionally reveal who the man was. The victim's mother and sister kill themselves.
As far as I can remember, Meursault never refers to this story again in the remainder of the novel. What is its relevance here or to the novel as a whole?
