Pursuit - Pursuit in the North Sea

Inspector Black, while at the Regents Bar, catches a vendor with a case of American made nylon stockings, worth about 500 pounds on the black market. Unfortunately, the source of these goods was not caught. The next morning, Inspector Black is in to the Home Secretary's office. He says "the Prime Minister is very concerned and takes a serious view of the violations of our Custom Laws. Smuggling has become big business, so much, in fact, that it is starting to have an effect on the economy. Something must be done."  The Inspector says "well sir, I hope you understand what we are up against. We know there is one large gang of smugglers with dozens of subsidiary gangs. They use planes piloted by ex-combat airmen, and torpedo boats to bring in the goods. We will have to have our own planes and boats to combat them."
