Clementine Scrivener

 was the daughter of Cedric Scrivener. Despite being at least older than Leela she had the mind of a child, and spent her time hanging around Gralstead House's mausoleum. She welcomed the arrival of Mordrega and called it a 'ghost'.

She was adept in flower arranging. She knew of the Gralstead. She placed Leela in a cage. (AUDIO: The Ghosts of Gralstead)
