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

Maya thought that Mr Nath was a crook because he had a strange appearance. He did not work but always had money to order his meals from restaurants, and even gave tips. The tenants at Shankar House said that he was mad, strange and unfriendly. He sat in his room all day, and nobody except a spectacled, fair, fat man visited him. He had no friends and she thought that it was so because he feared someone might recognise him and inform the police. She thought that the Sunday visitor was his accomplice in crime. She said that the visitor perhaps kept all the loot, and would come now and then to give a part of it to his partner for expenses.

Maya thought that Mr. Nath was a crook because of his strange appearance and the fact that he did not work. He never talked to anyone at Shankar House though he had been living there for more than a year. He had scars on his face which according to Maya, must have been the burn scars which would have got when police had set his house on fire. Moreover, he didn't receive any letters and had only one visitor to visit him. She said that the Sunday visitor must be his accomplice in crime and he came every now and then to give part of the loot to his partner.
