4. Prologue to "Expert Detectives"

 

Nishad, a boy of seven (also called Seven because his name means the seventh note on the musical scale) and his ten-year-old sister Maya are very curious about one Mr Nath. Then one day the children’s marble rolls into Mr Nath’s room, and Nishad gets a chance to see him. Is he a crook on the run? Why is his face badly scarred? Why has he no friends? Nishad’s mother, a doctor, knows Mr Nath as a patient, who is very polite.
