Lair of the White Worm: Chapter XV-XVI
Several comments made about Lady Arabella March in these two chapters, also apply to Lady Sylvia Marsh, as she is called in the film. "Cold-blooded." Yes, to both characters. "Plucky." Yes, to both characters. And, "At a disadvantage." Yes, especially, when Kevin plays his harmonica or mouth organ, and Lady Sylvia begins to move or dance like a snake
And as there is a hole or well-hole beneath Lady Arabella's house, Diana's Grove, in the book, so there is a hole beneath Lady Sylvia's house, Temple House, in the film.
