Mistry is more interested in having a reader come to know and understand the characters in his novel than he is in telling the reader about Bombay, so he does not spend time describing the geography. The story is told largely in conversation, because by hearing a characters own words the reader comes to understand the character better. For example, it is more effective to have Vilas Rane tell Yezad in his own words how he feels about his work as a scribe than is would be to have the author describe it for you.
