Hilda Sheen was an elderly woman and a patient at the Auriga Clinic. After being injected with gold, she came under the control of the Keratin, who directed her to acquire more gold. After being arrested by the police for robbing a jeweller's, she tried to get away and was picked up again near the clinic. Sarah Jane Smith read the newspaper report on her the morning after Dana Price tried to steal from her, and decided to investigate. Mrs Sheen was freed after the Keratin were defeated.
