I remember several of the Marilyn Ross DS novels took place during snowstorms & the characters would be essentially stranded on the estate. The characters would go back & forth between Collinwood & the Old House, but were unable to use the roads going into the village. I always liked those DS novels - the wintertime atmosphere was always very effective.
If Barnabas was still a vampire during a blizzard, what would he do about obtaining blood? If he transformed himself into a bat, would he be able to fly through heavy snowfall to the village? It would be interesting to see him in a situation where he would be forced to turn to one of the inhabitants of Collinwood for blood. Would Julia or Willie offer themselves? Would he, in a weak moment, bite Maggie? Carolyn? Elizabeth? Would Quentin be able to help Barnabas? Would would happen to Barnabas if he drank some of Quentin's blood?
