Just a little mystery scenario that popped into my head as recent thoughts about the Halloween story contest and the Netflix Wednesday series played tag in my head. As always, authors are more than welcome to use all, part, or none of these ideas as they wish (but definitely make sure your muse is okay with your decision - don't want to piss off that scary B with a serious itch!).
