El Sueño Del Celta by Mario Vargas Llosa

A historical novel that reconstructs the life of Roger Casement, an Irish diplomat who exposes the brutal abuses in the Congo and the Amazon rubber camps, becomes a passionate advocate for human rights, and later embraces Irish nationalism—leading to his arrest and execution for treason; through intimate interior monologue and factual episodes it examines colonial violence, moral conflict, identity, and the cost of idealism.
