Some of the stories that are part of this literary work are anecdotes that were told to me by different characters, others are products of the author's imagination.
 The title of the book belongs to one of the stories that have been published, based on the guacas of drug trafficker Pablo Escobar Gaviria, one of the richest men on Earth. ''The patron of evil'', as he was known in the underworld, was the leader of the Medellin cartel, which was then responsible for 80% of the world's cocaine.
