The Tale of Two Bad Mice is a children's book written and illustrated by Beatrix Potter, and published by Frederick Warne & Co. in September 1904. Potter took inspiration for the tale from two mice caught in a cage-trap in her cousin's home and a dollhouse being constructed by her editor and publisher Norman Warne as a Christmas gift for his niece Winifred. While the tale was being developed, Potter and Warne fell in love and became engaged, much to the annoyance of Potter's parents, who were grooming their daughter to be a permanent resident and housekeeper in their London home. The tale is about two mice who vandalize a dollhouse. After finding the food on the dining room table made of plaster, they smash the dishes, throw the doll clothing out the window, tear the bolster, and carry off a number of articles to their mouse-hole. When the little girl who owns the dollhouse discovers the destruction, she positions a policeman doll outside the front door to ward off any future depredation. The two mice atone for their crime spree by putting a crooked sixpence in the doll's stocking on Christmas Eve and sweeping the house every morning with a dust-pan and broom. The tale's themes of rebellion, insurrection, and individualism reflect not only Potter's desire to free herself of her domineering parents and build a home of her own, but her fears about independence and her frustrations with Victorian domesticity. The book was critically well received and brought Potter her first fan letter from America. The tale was adapted to a segment in the 1971 Royal Ballet film The Tales of Beatrix Potter and to an animated episode in the BBC series The World of Peter Rabbit and Friends. Merchandise inspired by the tale includes Beswick Pottery porcelain figurines and Schmid music boxes. Two Bad Mice reflects Potter's deepening happiness in her professional and personal relationship with Norman Warne and her delight in trouncing the rigors and strictures of middle class domesticity. Author Helen Beatrix Potter (28 July 1866 – 22 December 1943) was an English writer, illustrator, natural scientist, and conservationist best known for her children's books featuring animals, such as those in The Tale of Peter Rabbit. Born into a privileged household, Potter was educated by governesses and grew up isolated from other children. She had numerous pets and spent holidays in Scotland and the Lake District, developing a love of landscape, flora, and fauna, all of which she closely observed and painted. Though Potter was typical of women of her generation in having limited opportunities for higher education, her study and watercolours of fungi led to her being widely respected in the field of mycology. In her thirties, Potter self-published the highly successful children's book, The Tale of Peter Rabbit. Potter began writing and illustrating children's books full-time. Potter wrote about 30 books; the best known being her 24 children's tales. With the proceeds from the books and a legacy from an aunt, in 1905 Potter bought Hill Top Farm in Near Sawrey, a village in the Lake District, which at that time was in Lancashire. Over the following decades, she purchased additional farms to preserve the unique hill country landscape. In 1913, at the age of 47, she married William Heelis, a respected local solicitor from Hawkshead. Potter was also a prize-winning breeder of Herdwick sheep and a prosperous farmer keenly interested in land preservation. She continued to write and illustrate, and to design spin-off merchandise based on her children's books for British publisher Warne, until the duties of land management and her diminishing eyesight made it difficult to continue. She died of pneumonia and heart disease on 22 December 1943 at her home in Near Sawrey at the age of 77, leaving almost all her property to the National Trust.
