The Thirteen Little Black Pigs

Popular Victorian children's book. According to Wikipedia: "Mary Louisa Molesworth (29 May 1839 – 20 January 1921) was an English writer of children's stories who wrote for children under the name of Mrs Molesworth... "Mary Louisa Molesworth typified late Victorian writing for girls. Aimed at girls too old for fairies and princesses but too young for Austen and the Brontës, books by Molesworth had their share of amusement, but they also had a good deal of moral instruction. The girls reading Molesworth would grow up to be mothers; thus, the books emphasized Victorian notions of duty and self-sacrifice."
