I know the author personally, have followed his work over many years, and consider him to be one of the top authorities on intelligence writing in the Spanish language. I recently worked with him in Spain on an initiative he has been developing, to help the Spanish government and Spanish commerce make better use of open sources of intelligence while also refining their methods in relation to data integrity, product integrity, and system or behavioral integrity.
Although I am not familiar with all the publications in Spanish on intelligence, people I trust tell me that this is one of the top books in Spanish. I do not look for it to be translated soon, but would certainly recommend to any publishing house that they consider doing so, as we are all [except the Western governments] moving toward M4IS2 hybrid eight tribe governance, and this is something the author is helping to explain to all governments and business and academic and non-governmental communities that work in the Spanish languages.
M4IS2: Multinational, Multiagency, Multidisciplinary, Multidomain Information-Sharing and Sense-Making
Eight Tribes: Academic, Civil Society, Commercial, Government, Law Enforcement, Media, Military, Non-Governmental / Non-Profit
Rather than list specific books I also recommend here, I want to point readers to my full list of most intelligence books that I have reviewed for Amazon, just search for intelligence (most and get right to it with links to the Amazon pages for each book.
