Lair of the White Worm: Chapter IV
For the first time we meet Lady Arabella March of Diana's Grove, or as she is called in the film, Lady Sylvia Marsh of Temple House. Though, the character in the book apparently likes to dress in white, and the character in the film apparently likes to dress in black, the dress alone is sufficent enough to attract atteion for both characters. And both characters have a sinuous figure like a snake.
We also for the first time meet Mr. Caswell. One advnatage the film film has over the book, is that while the villainies in the book are divided between Caswell and Lady March, in the film, all the villainies are performed by Lady Marsh.
We also meet Caswell's black servant, Oolanga, who has no counterpart in the film. Which is probably a good thing, as I have yet to meet anyone who has not described Oolanga as being one of the most racistly depicted characters in fiction.
We also meet the Watfords or Trents as they are called in the film. While Mr. Waford or Trent is a tenant of Caswell and not D'Amptin, they are or were farmers and lived at Mercy Farm. (Mercy Farm is apparently the only name that has not been changed from book to film.)
We also meet his granddaughters or daughters in the film, Lilla and Mimi. While sisters in the film, they are cousins in the book. Lilla being the older at about 20, and Mimi being the younger at about 19. Or a difference of seven and five years from the characters in the films.
If Eve represents Lilla in the book, and Mary represents Mimi in the book, then Angus or Adam loves the younger and more dark complected of the two cousins or sisters.
