Neil Bissoondath is a Canadian author. His has written six novels, one novella, and two collections of short stories. Many of his works depict characters who are struggling in life. They must face challenges which either insure their survival or constitute their demise. Given that one specific novel is not named, it is hard to speak about the specific comeuppance in context.
This said, comeuppance is the consequences or punishment one faces. This punishment matches the "crime." Essentially, the punishment does not fall short or exceed the crime. Historically in some literature, famous in Shakespeare, the punishment tends to exceed the crime.
