The novel argues that authoritarian rule degrades a society less through spectacular violence than through countless small compromises: businessmen trading loyalty for contracts, journalists writing what is safe, servants covering for masters. Because each person's corruption is local and self-justified, no single moment of collapse can be identified, which is why Santiago's question of when Peru 'fucked itself up' has no answer.
Santiago rebels against his class by opting out: leaving his family, drifting from the student communist cell, and settling into an unambitious newspaper job and marriage. The novel shows this withdrawal leaving him paralyzed and self-reproaching rather than clean, since he still works inside the system, writing editorials for a compliant paper.
The novel splices several conversations from different years into single passages, so a line spoken in 1963 answers a line spoken in 1951. Reading this way forces you to see present events as direct continuations of past choices, making causation and moral responsibility visible across time rather than in isolated scenes. It is a way of seeing how memory, evasion and consequence coexist in one exchange.
