Why does Maya think that Mr. Nath is a crook? Who does she say the Sunday visitor is?

Maya’s view abut Mr. Nath was that she did not think him to be a poor man and was sure that he was a crook, because he did not talk to anybody and had no friends. She believed that his scars were the result of some shootout with police. He didn’t work anywhere and sat at home all day and there were no visitors at his place, except for a guest who came to visit him every Sunday. She thought that Sunday visitor was Mr. Nath’s partner in the crime. He kept the money from the loot and came to give Mr. Nath his share every Sunday.
