She was portrayed by Janette Scott. For she lived in Femm Hall her whole life so she could have her claim to the share of the family fortune (a long standing will stated, only the last member that stayed in tha house could have it), at first seemingly normal unlike her family (each one caught up in an obsession or unsual behaviour for them to deal with the will's specifications), but her whole life she lived in fear of the house and what it did to her family. After many years this finally drove her mad.
