In this article, a recently published Dutch book on corruption in the port of Rotterdam is reviewed. De Schiedamse cocaïnemaffia. Een corrupte douanier, doorgewinterde criminelen en duizenden kilo’s coke was written by journalist Jan Meeus from NRC Handelsblad. The book can be seen as a case study of a customs officer – Gerrit – who fell for the big money. It gives a good insight into the connection between the legal and the illegal world and how this is experienced by those involved. The information in the book is based on seven large criminal files and dozens of conversations with people mentioned in those files. Meeus also attended the criminal proceedings intensively. It is now known that the film rights of the book have been sold and that Meeus will be writing the screenplay for the feature film together with director Jean van der Velde.
