" Miss Haxby, I thought, gazed at the plodding women with a kind of satisfaction. ‘See how they know their places,’ she said. ‘There must be kept a certain distance, look, between each prisoner.’ If that distance is breached, the offending woman is reported and loses privileges. If there are women who are old or sick or feeble, or if there are very young girls—‘We have had girls in the past—haven’t we, Miss Ridley?—of twelve and thirteen’—then the matron sets them walking in a circle of their own.
