Amhurst

Rebecca Barnes-Cabot (Amy Tiehel) used to be a twin. She and her sister, Rosie went to stay with their alcoholic and sometimes abusive grandfather after their mother's death. When they were ten-years-old, Rosie went missing.... and never returned.

It has long been suspected that their grandfather, Meryl Barnes (Tim Field), was responsible for little Rosie's disappearance.
