When the lights go down near the city of the Ringwraiths, Gollum is anxious to continue east as quickly as possible. Frodo and Sam follow, heedless of the danger — which is all around in this place where even the flowers are twisted and foul, the watchtower inexplicably revolves, and an evil army is about to issue from the gates any minute now. All this, plus weather-nerdery about lightning, nightmare-inducing word-nerdery about charnel houses, and your hosts’ presumptuous ideas for changes to Tolkien’s books and the movies based on them.
