The Sucking Pit

Tom 'Romany' Lawson, aged woodman, is discovered dead. His virginal niece Jenny mixes up a potion described in his diary and is immediately transformed into a murderous sex maniac. She ends up helping a giant gypsy leader named Cornelius to regain the local ancient Romany burial site, the Sucking Pit, by blackmailing the owner of the land with sexual favours. But her ex-boyfriend, a reporter, is astounded by the changes within her and won't give up the search for the truth.
