I would have thought that redhead was tracking Manny Machado by now but if you're "going to the backwoods of Maine" clearly there is still danger. And yes I realize backwoods means mountains and Maine means some other state, but so does she.
About this fiancée. Careful. She could be in league with your tormentor and her "brother/mother/whoever else". It will be difficult because there will be no obvious signs. Don't bother with her phone, computer, etc.. Check out stuff like her makeup kits and shoes for communication and tracking devices. Are all the dogs yours or did she introduce one?
