The story is about siblings Maya and Nishad. They were very curious about Mr.Nath, who was a patient of their mother and living in Room number 10 of Shankar Guest House for more than a year. Maya thinks that Mr.Nath is a criminal who is hiding and had got scars on his face during a shootout with the police. And also thinks he had lots of treasure in his trunk. However, Nishad thinks that Mr.Nath is a poor and sick person, starving as he doesn’t have enough money. And according to him the scares on Mr.Nath’s face is burn marks.
One day Nishad went alone to Mr.Nath’s room and gave him a piece of chocolate. When Maya came to know about this incident she was very disappointed as she missed the chance. But she was also excited at the same time as his brother had found something about Mr. Nath. Nishad says that he went to Ramesh. Ramesh told him that Mr. Nath is not very specific about the food, he takes the same meal and two cups of tea, one in the morning and one in the evening. Mr. Nath pays him in cash and also gives tips. Ramesh also says that Mr.Nath has a visitor every Sunday who is the same person every time. But Maya thinks that the visitor is Mr.Nath’s crime partner and who comes to give him his share of the money. Both Maya and Nishad were discussing Mr. Nath.
The next day, their schools were reopening after the summer holidays. But due to the heavy rain, there was an unexpected holiday. Maya thought to use the time in writing down the facts about Mr.Nath which will help to trap him. Whereas, Nishad was lying on the bed and reading comics. Maya asks Nishad whether he wants to listen to what she had written. She beings with her concern about the name of Mr. Nath, she thinks this might be not his real name, and says that tenants of Shankar House think that Mr.Nath is mad, strange, and doesn’t have any friends, doesn’t talk to anyone, never receives any letter, doesn’t work but still lives in the room for more than a year, doesn’t have any visitor except that Sunday man.
