The day after the Venlo-incident, I found in my father's room a very interesing book about this Velo-incident written by Johan P. Nater, the author thinks it strange that people like mr. Paul Koster,former Dutch Marine-officer, come to investigate on the incident.He was a European representative of the American Armament Corporation and he had his contacts within the Secret Intelligence Service of the Deuxième Bureau. His part in the Venlo-incident has never been fully understood (p.107)Koster was probably killed by Gestapo in Grenoble. Other sources say that he died in Paris 1 January 1941.
