Two spies land near Hythe in a dingy. They have a wireless set and an elementary cypher with orders to send back information of military importance; they had been given to understand that an invasion of the Kentish coast was imminent. They separate on landing.
The two men are of Dutch nationality and were completely untrained for their task. It seems they were selected because they had committed some misdemeanors known to the Germans and could be blackmailed into undertaking the enterprise.
Another pair of spies lands at Dungeness. One is German who speaks excellent French but no English. The other claims to be Dutch and speaks fluent English.
