question: Whose parents did the White Bitch kill?
context: Lucy finds that her adoptive father, a museum curator, has been attacked by Silas. Before dying, he gives clues which lead her to a "Golden Ticket" in a vending machine candy bar. During "comedic" situations, Golden Tickets are found by other orphans, which include Edward, a disillusioned monk trainee; Susan, a displaced adopted girl; and Peter, a mutant at Mutant Academy who is often teased for his chicken-like wings. All four meet up at Willy's Chocolate Factory. Willy reveals his plot to use them all as a special ingredient in his treats.
  In an effort to hide from the maniacal Willy, Lucy finds a wardrobe. On the other side, in the middle of a wintry forest, she finds Mr. Tumnus, who welcomes Lucy to Gnarnia and warns her of danger. The others follow Lucy to Gnarnia, and Edward meets the White Bitch. She convinces him to trap the other orphans in order to become the king of Gnarnia in her White Castle. All four go to Tumnus' house, where they discover that they are all related to one another in a copy of the famous painting The Last Supper, and that the White Bitch killed their parents. They ally themselves with Harry Beaver, Tumnus' life partner, to defeat the White Bitch.
