I’m inclined to think it does, because if you have an idea about a pub scene or a murder, you have to decide where it will take place and this gives you a location – streets, walkways, pier, fishing boats, yachts. (All with possibilities).
Also you have the variety of people who will frequent the locality – fishermen, yachtsmen, tourists, locals, pub crawlers, day trippers.
In ‘Body in a Bag’ I decided a murder could take place in a yacht. It was unfortunate for the victim that the mist delayed the yacht from sailing and forced the murderer’s hand.
