The Loss of El Dorado by V. S. Naipaul
Focusing on the early 19th century, when British occupants inflicted a reign of terror on the island's black population, V.S. Naipaul's recreation of the history of Trinidad exposes the barbaric cruelties of slavery and torture and their consequences on all strata of society - from the idealist to the reactionary - in an account which penetrates aspects of a complex society.
