S3·E22 Episode 187

Vera thinks that Lizzie hasn't escaped at all and that the women are hiding her to play a joke on the officers. Jim says the same thing to Erica, and Erica throws a fit of pique and has the women confined to their cells until Lizzie turns up - or the women admit what they are doing. Lizzie selects some clothes and a hat from a charity shop then pretends to have left her bag on the bus: the woman running the shop not only says she can take the clothes and pay for them later, but also give Lizzie two dollars from her own purse. Lizzie makes the money go further by buying something in a chemist's and conning the assistant into giving her change from ten dollars instead of the two she really gives him. Doreen predicts Lizzie will be back by the next day at the latest. David goes to Bea's cell to find out what's going on, as he suspects it's another trick to have his classes cancelled. Vera finds him and tells him off for straying outside his allotted area.
