However, he never stops writing about a subject he always were passionate: the far west. His novels of “bang bang” are true films that catch the reader from the first to the last page in such a way that, sometimes, the cars assembly plants companies used to forbidden their employees to get into with this books, because, they were able to leave the production line until they finish completely the reading.
