Sarah Castle was the young daughter of Mrs. Castle, the housekeeper at the stately mansion of Collinwood in Collinsport, Maine in the early 19th century. Sarah Castle became very close to Angelique Collins, a witch and lover to Collinwood's patriarch, Charles Collins. Angelique once gave Sarah a keepsake and told her that so long as she held onto it, she would always remember her. In the year 1810, Sarah was upstairs in the 3rd floor tower room of Collinwood where she witnessed Angelique being executed for witchcraft on the grounds outside.
