How do sherlock holmes and arthur conan doyle handle class differences

In the novel, the element of class differences is added by Stapleton. ​John Stapleton was an extremely cunning and resourceful man. He knew how to play upon people and obtain the thing that he coveted. Although he belonged to the titled Baskerville family, circumstances had been such that he had grown up without having any access to the considerable means of his family. Therefore, he can be taken as the representative of the have-nots, those who grow up not in the lap of luxury but by their wits. He wanted to get his hands on the ancestral property but through unfair means and this is where he exposes himself as a criminal mastermind. He had the intelligence of a man who came from a good family but in the absence of opportunities, he had taken to a life of crime. This can be a seen as a statement on how circumstances and opportunities define the course of someone's life. However, we are also made aware of the fact that one's background determines their station in life and it is evident from Holmes' thinking. He can identify the culprit through certain socio-economic markers. The author has kept it quite subtle but the nuances are easily discernible in that Holmes shows that ultimately it is about money. Crimes are committed because of inequality in society in terms of one's socio-economic conditions.
