They did not understand. The legends all said the same thing. The amulet, when used when the comet was passing, would turn them into humans once more. It did, it turned them into humans for a couple of days, but then they were back to vampires. The Sackville-Bagg family had spent over three hundred years searching for the amulet so that they could become humans, but it only lasted a couple of days. When they became vampires again they moved back into their graveyard home. They hoped to find out what happened. Why were they once again vampires? With Rookery no longer alive to bother them, they hoped it would easier for Tony and his family to help.
