In this elegant and literate adventure novel set in 1920's post-revolutionary Mexico, Paco Ignacio Taibo II is searching for a hero, specifically a leftist hero, and he thinks he has found him in the person of Sebastián San Vicente. But everyone, including the baffled novelist, is trying to figure out exactly who San Vicente really is. There is some record of San Vicente in FBI records during the Wilson era, and some mention of him in anarchist records and rumors, but the rest has to be filled in. And who better to do this than Taibo? Meanwhile, with Taibo busy in the background trying to resolve the mystery of his hero's identity, San Vicente goes about his heroic avocation of organizing strikes against the capitalists, dodging thugs and hiding out from the Mexican Army.
