1: i'm getting surrell's books on amazon right now, god knows why i haven't gotten them already.
2: i thought i dreamt up the green mist idea. unrelated, but there's a secluded and very dark stretch of woods in the city with a windy 2 way road (that leads to heaven for the occasional drunk driver unfortunately) within my city. it gets very foggy and people call it "green mist" because they swear it's green late at night.
at any rate, it's a very british, hammer-horror thing to do. maybe it could be enhanced slightly?
