The novel is notable for its use of the extreme "invasionist" model of Indo-Aryan migration into India, but for portraying the Aryans in a negative manner characteristic of post-World War II anti-Nazi sentiment and Dravidianist ideology of the era. It turns out that the disruptions to the dig arose from an attempt by a group of Brahmins to conceal evidence of a terrible massacre committed by the Aryan invaders, who had built a monument to their victory and had thrown to their deaths thousands of Dravidian workers who had created it. The monument, dedicated to Indra, is eventually uncovered, containing a large wall-carving depicting the Aryans crushing their enemies, and emphasising the racial differences between the two groups.
