Bea and Judy give Kathy's cell a thorough check for any more booby-traps. Inspector Grace arrives to see Kathy. Vera is most unpleasant to him and explains to Terry that she's had dealings with him in the past. Dinah eavesdrops on this conversation. Bea and Judy are concerned about Lizzie, who is moping about and won't reveal why. Terry arrives to take Kathy to Grace. Kathy doesn't want to go and Bea tells her she doesn't have to. Terry then points out that if she doesn't go the police will certainly suspect she knows more than she does. Bea concedes to this point and Kathy goes with Terry. While in the corridor, the riot alarm is sounded. Terry leaves Kathy behind a locked gate while he goes to investigate. Dinah sneaks up behind Kathy and smashes her head into the gate twice. Terry finds her a minute later unconscious. Jim tells the women in the laundry that Kathy has been bashed. Bea is getting pretty irritated with the unknown assailant.
