neck and who almost dies as a result. Adam learns that another child has already been killed by a snake bite and that animals have also been killed mysteriously throughout the county. Caswall's Black African servant, Oolanga, a man obsessed with death and torture, prowls around the Castra Regis estate, enjoying the carnage left by the White Worm. Adam's mongoose attacks Arabella, who shoots it to death. Adam buys more mongooses and keeps them locked in trunks when not using them to hunt. Arabella tears another mongoose apart with her hands. Oolanga takes a liking to Arabella, perhaps sensing something violent in her, and makes advances. Arabella scorns Oolanga and is deeply insulted that he would dare to approach her. In an attempt to win her over, Oolanga steals one of Adam's trunks (which he believes is filled with treasure, but is actually just another mongoose), and Adam follows Oolanga. Arabella lures Oolanga to a deep well in her house, then in rage and disgust murders him by dragging him down into the deep pit tunneled through a bed of white china clay. Adam witnesses the murder, but has no evidence of it apart from his own word. Arabella writes him a letter the next day, with the previous night's events twisted, claiming her complete innocence. Adam and Sir Nathaniel begin to suspect that Arabella is guilty of other crimes and that she wants to murder Mimi Watford.

The White Worm is a large snake-like creature dwelling deep under Arabella's house at Diana's Grove. It has green glowing eyes and feeds on whatever living creatures it can find to eat. Sir Nathaniel believes the Worm is descended from dragons, who traded their physical power for cunning. The Worm ascends from its pit and seeks to attack Adam and Mimi Watford in the forest of Diana's Grove. Adam is able to foil Arabella's multiple attempts to murder Mimi, and Arabella offers to sell Diana's Grove, which Adam buys with the aim of destroying the White Worm. He plans to fill the pit with sand and set dynamite to kill the Worm while it is underground. Caswall's last visit to Lilla ends in her
