chunk: The White Worm is a large snake-like creature that dwells in the hole or pit in Arabella's house located in Diana's Grove. The White Worm has green glowing eyes and feeds on whatever is thrown to it in the pit. The White Worm ascends from the pit and seeks to attack Adam and Mimi Watford in a forest.
  Adam plans to pour sand into the pit and to use dynamite to kill the giant White Worm while it is inside the pit.
  In the final scene, Adam Salton, Mimi Watford, and Nathaniel de Salis confront Arabella and Edgar Caswall. A thunderstorm and lightning destroy Diana's Grove by igniting the dynamite.
