When Mary Ann is sent from her native Tyneside to become a pupil at a high-class convent boarding school on the South Coast, the idea in her benefactor's mind was that she should be turned into a little lady. In this, the third story in the Mary Ann series, Mary Ann is seen again as that irrepressible child of Tyneside in all her cheeky delightfulness. As usual, however, despite the seemingly over-powering difficulties, everything is sorted out satisfactorily in the end.
