"I can do whatever I like, out here I can call it self defence."
Kay first started out as a bookkeeper at Andrew Reynolds' work factory, she gets very friendly with the women on the work release scheme, especially Margo Gaffney and Judy Bryant, when she places a bet with Margo and Judy Bryant gives her winnings to Kay to get her a dress for her escape (127). She has been stealing goods from the factory for quite a while and sees the opportunity to blame it on the women on the work release: she sets up Noeline Burke to be caught throwing a roll of material out of the factory window to her brother (132). When Andrew Reynolds announces the firm's accounts are to be audited, she stuffs the factory pay envelopes with paper and "borrows" the money to place a huge bet to pay back what she has stolen but her deception is discovered while she is away and she is caught when she returns to replace the stake money (134). Remanded to Wentworth for embezzlement and theft, where the women prey on her and try to tempt her back into gambling to undermine her defense of accepting psychiatric treatment for her compulsive gambling. Dr Weissman gives evidence against her at her trial and she is sentenced to 5 years (140). After Bea has been sent to solitary for 10 days for giving Kay a bashing (142), Kay takes over the book from Margo, until Judy and Lizzie trick her into accepting bets she can't pay out for.
After she's been set up, she runs to Lizzie Birdsworth's cell and attacks her until Linda Jones defends her by smashes Kays head with a jug kettle, she later dies of a blood clot to the brain. Linda was taken to solitary for 12 days.
