Quote 1
"All unfortunate natives are criminals at heart, for the simple reason that they live south of latitude 30." (2.18.1)
Here, McBryde professes his racist view of Indian psychology as a scientific fact: according to McBryde, it's the geographical location that makes the Indians criminal. Of course, this doesn't explain why someone like himself, who was born in Karachi, happens to be a policeman. Ironically, McBryde is discovered to be having an affair later in the novel.
Quote 2
"[…] When you think of crime, you think of English crime. The psychology here is different […] Read any of the Mutiny records; which, rather than the Bhagavad Gita, should be your Bible in this country. Though I'm not sure that the one and the other are not closely connected […] (2.18.25)
McBryde again rambles on about Indian criminal psychology. He's referring to records of the Mutiny of 1857, an important event that many regard as the first move toward Indian independence (for more on this, check out our "Setting"). But to the British this event signifies only the Indians' natural tendency to violence and disorder, as McBryde's association of the Mutiny with the Bhagavad Gita, a sacred Hindu text, suggests.
