'[Victorian] children's literature becomes extremely moralistic, associating violent punishment with even minor misbehaviour: obey your parents, or you'll become an orphan, do not play with matches or you will burn the whole house down.' [Anne Lundin, '"Victorian Horizons: the Reception of Children's Books in England and America', The Library Quarterly 64:1, 34]
