'Premium' (iii) was a British deception undertaken as one of several similar efforts to draw German attentions away from the Normandy area as the late planning of 'Overlord' was being completed (February 1944).

A double agent known as 'Mullet' told an Abwehr contact in Lisbon, the capital of neutral Portugal, that he had recently taken employment with an association of British insurance companies specialising in fire insurance and therefore possessing a major database of buildings in many parts of the world. 'Mullet' was thus able to pass on the 'story' that the British authorities had asked the insurance companies for any information they might possess about Norway (especially Narvik and strategic areas farther to the south), Belgium and north-eastern France.
