The TV programme had a misprint, last name should have been Fowler, therefore the answer is 'The Thin Blue Line' I have managed most of this puzzle but am stuck on a few place names and not sure whether I have found all the colours in the story.
Thanks for Insp. Fuller/Fowler info. As for the colours I have found 25 but don't know if they are all right.
