First, I should confirm the author's full name and any related works. Maybe there's confusion with another author? There's a Colombian writer named Rodolfo Benavides? I'm not sure. Wait, there's a book entitled "La Verdad Está en las Manos" that might be linked to a person named Rodolfo Benavides. Let me check if that's a real publication. If not, perhaps the user is referring to a PDF they found online, which might not be an official publication. In that case, I need to caution the user about the legitimacy of the PDF and the source.
