This extraordinary scholar benefits from being given access by an enlightened secret intelligence service whose Parliament demands full transparency as required. His book is one of those very, very few that can legitimately claim to be fully informed from a full examination of all classified messages and archives, as well as the usual unclassified or publicly available information, and the author is himself an extraordinary scholar and a founding member of the Netherlands Intelligence Studies Association, which which his photo connects absent an English-language biographic page.
This book is worth getting at any price from any source–we have urged the author to send us the book for a reprint at cost if his publisher will not do it imemdiately. It should not be out of print.
Below left are his remarks on the book and his investigation as made to OSS '04.
