that he can help him get revenge on Mulgarath for killing his family. Mulgarath releases Simon so he can fetch the Book for him. Jared finds Simon and both fight over the Book before they are chased by the goblins. The twins flee back to the house, and Mallory, upon almost being ambushed by the goblins, which cause her to realize Jared was right, fights them off with her fencing sabre. After failing to try and burn the Book due to a protective spell over it, the children decide to visit Arthur's daughter, their great-aunt Lucinda Spiderwick, for advice.
