Mary Roy's brother, George Isaac, who figures in the book as Uncle Chacko, is ambiguous on the question: "Mary Roy is Ammu," he contends, but declines to comment on the identity of Velutha, Ammu's paramour, saying: "I would prefer not to answer that question." Isaac thinks the book contains an explosive message—"that an aristocratic Christian woman breaks the rules by having sex with a low-caste Hindu and yet nothing happens. The universe does not come to an end." This message may not go down well with the Christian plantation owners in their stately mansions along the banks of the Meenachil. Curiously, this is also the strata that celebrates Arundhati's accomplishment. "She has put Aymanam on the world map," says Thomas Kollenkeril, an estate owner whose wife Basil teaches at Corpus Christie.
