Half a Life is largely about people of mixed racial descent—half-castes, mestizos, mulattos, Euro-Africans and others—half-whites, half-browns or blacks. However physically desirable they may be, they remain socially unacceptable to the majority which prides itself on being pure-blooded. In a prefatory note, Naipaul describes his novel as "an invention. It is not exact about the countries, periods or situations it appears to describe". In fact, his story begins in India, travels to England and ends in a Portuguese colony on the west coast of Africa. The main theme in every country is miscegenation. In India, a Brahmin boy, instead of marrying a Brahmin girl approved of by his parents, takes a fancy to the plainest looking Harijan girl in his college. There is no way out because the girl’s uncle is a powerful trade union leader. His niece’s reputation has been compromised by the two being seen sitting together in the college classrooms and a cafe. They marry and lose their castes. They have a son and a daughter who find it comfortable to pose as Christians. Meanwhile, the outcaste-Brahmin, who is by now in deep trouble because of charges of corruption, seeks sanctuary in a temple, takes a vow of silence and becomes a minor godman. Amongst the celebrities who come for his darshan is Somerset Maugham. The father inserts Maugham’s first name in the middle of his son’s—Willie Somerset Chandran, the hero of Naipaul’s story.
