Mario Vargas Llosa launched his "La fiesta del Chivo" novel in Madrid, Spain yesterday. The renown Peruvian author and politician said the grip late Dominican dictator Rafael Trujillo had on the psyche of the Dominican population for three decades was what inspired him to write the novel. Vargas Llosa said that it took him 25 years to write the book, including several months of research in the DR. In the novel, Vargas Llosa creates fictitious characters and situations, but he says that what happened to them could really have happened.
