The lesson is a story of two young detectives who were curious about a man who is concerned about a person whom they find very strange, who was polite, a recluse with health problems. Nishad's mother, a doctor by profession, knew the man as a patient. They persistently searched for evidence against him. The person never has visitors to his home, does not have friends, does not talk to people, is very skeletal and pays excellent tips to Ramesh, who brings his food to his room. However, these were more imaginary than incriminating.
