Maya thought that mr.nath is a crook because he had a very strange appearance.He didn't work but had money to order his meals from restaurants and give tips.  He would sit in his room all day, and nobody except a spectacled and fair man visited him on Sundays. He had no friends. Maya thought that the Sunday visitor was his accomplice in crime. She thought that the visitor perhaps kept all the loot, and would come to his house to give a part of it to his partner.
