I’ll data dump whatever I can seem to remember.
The title was something like “Red _____”. Part of me wants to say it was a light source, like Red Candle or Red Sun, part of me wants to say it was Red Queen or other royalty / title.
It was shown on TV, may have been made for TV. It was at least two parts as I tried to record it as a kid. It was shown on TV then between 1990 and 1999 and not on cable, so ABC / CBS / NBC / PBS / Fox.
I seem to remember some kind of murder / assassination attempt using a worm in a bed.
It was sci-fi in that it wasn’t our reality, but I seem to remember more along the lines of clothing that suggested like a Robin Hood / medieval fantasy setting.
