Who is a detective

Oxford Dictionary gives the meaning as a person whose occupation is to investigate and solve crimes. Crime is an illegal act for which punishment may be given by the government. That may be reason Indian writer Satyajith Ray gave his detective a wider scope by giving the character a claim as he is a Satyanweshi: meaning seeker of truth. So a Satyanweshi can solve anything that leads to truth, and that need not necessarily be a crime.
