The Secret of Marrowbone

In the late 60's, Ms. Marrowbone travels from England to the Maine with her children Jack, Billy, Jane and Sam to flee from her evil husband. The siblings befriend the youth local librarian Allie, who lives in a nearby farm, and have a wonderful summer together. But soon their mother that is ill becomes terminal and asks their siblings to promise to stay in the house together until Jack is twenty-one and becomes capable to assume the family. She dies and they bury her in the property, while Jack and Allie fall in love with each other. Jack hides the death of his mother from the locals, and when the lawyer Porter requests her signature to transfer the real estate to her name, Jane forges her signature, but they need to pay a two-hundred-dollar tax. They are moneyless and Jack is forced to use the dirty money from his father that they had thrown away in a cave. But soon their evil father appears in the real estate and Jack hides his siblings in the attic. Soon a ghost terrifies the siblings, and all the mirrors are covered or hidden by Jack.
