"Well documented, interesting, practical, and useful book"

Andrew S. Clydeham, former intelligence officer (MI6, British Foreign Intelligence Service)
"Dear Mr. Dylewski,
I have just finished your book. I would like to tell you that it has its place in a police academy or an intelligence training center. I believe that this is already the case in France and in Belgium.
Simple, practical, concrete. A synthesis of the different aspects of intelligence and investigation. My only criticism is the total absence of references to the moral and ethical aspects of these methods."

Why is the book only available on Amazon (and not on this site)?
Because I have no choice. Readers live in the USA, Great Britain, Australia, India, South Africa...and the postage from my home country, Belgium, would double the price of the book.
