Book excerpt: In The Old Gringo, Carlos Fuentes brings the Mexico of 1916 uncannily to life. This novel is wise book, full of toughness and humanity and is without question one of the finest works of modern Latin American fiction. One of Fuentes's greatest works, the novel tells the story of Ambrose Bierce, the American writer, soldier, and journalist, and of his last mysterious days in Mexico living among Pancho Villa's soldiers, particularly his encounter with General Tomas Arroyo. In the end, the incompatibility of the two countries (or, paradoxically, their intimacy) claims both men, in a novel that is, most of all, about the tragic history of two cultures in conflict.
