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 doll's house 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.
