When she returns to the manor, she finds that her family was murdered and Barker that is still alive shows her a silver bracelet on the floor with the name of the killer. He tells that she is in danger since the killer will return to the manor to retrieve the bracelet. Barker dies and the killer comes back to the house. Will the frightened Sarah flee from him?
