The Prisoner has returned to
after a most dangerous sea voyage in 'Many Happy Returns.' He’s encountered a belligerent housemaid, gained the help of Mrs. Butterworth, and finally convinced the Colonel and Thorpe enough to be intrigued by his story. The Colonel puts checks put into motion of their ex-colleagues story, and finally convinced enough, call in a Naval Commander and RAF Group Captain to help calculate a search area for the Village. London
Then having calculated a search area of some 1,750 square miles, the Village thought to be lying somewhere on the coast of Morocco, South West of Portugal and Spain, the Naval Commander looks at the map saying "Just about here," who then takes a pencil and scribbles all over the search area!
Yes, "Just about here," it seems as though the Naval Commander obliterates the search area on the map, perhaps so that the viewers could not see where the Village might be! This scene never ceases to amuse every time I watch it.
