Alonso Salazar, former Mayor of Medellin, has published a number of books on the reality of Colombia, especially in terms of understanding the phenomenon of drug trafficking and its sickly hold on society. No nacimos pa´semilla (1990), La parábola de Pablo (2001) and Profeta en el desierto: Vida y muerte de Luis Carlos Galán (2003) are his most important books. He will talk to the writer Mario Jursich about his most recent book, No hubo fiesta, in which the author draws intimate portraits of the main figures in the war, including Bateman, Pizarro, Marulanda, Iván Ríos and Carlos Castaño.
