Other, less volatile prisoners included elderly, garden-loving Jeanette "Mum" Brooks who was incarcerated for the euthanasia of her husband who had terminal cancer, teddy-clutching misfit and childlike Doreen Anderson (Colette Mann), alcoholic former cook recidivist Lizzie Birdsworth (Sheila Florance), who apparently poisoned a group of shearers and seductive prostitute Gladys "Marilyn" Mason (Margaret Laurence), who seduced prison electrician Eddie Cook (Richard Moir). The prison officers (or "screws", as the prisoners call them) included firm-but-fair well-heeled governor Erica Davidson (Patsy King); dour deputy governor Vera Bennett (Fiona Spence), who was always wanting to become Governor and was nicknamed by Franky "Vinegar Tits"; and firm but compassionate senior officer Meg Jackson (later Morris) (Elspeth Ballantyne).
