"The Tale of Two Bad Mice" had its genesis in June 1903 when Potter rescued two mice from a cage-trap in her cousin Caroline Hutton's kitchen at Harescombe Grange, Gloucestershire, and named them Tom Thumb and Hunca Munca after characters in Henry Fielding's play, "Tom Thumb". Tom Thumb was never mentioned in Potter's letters after his rescue from the trap (he may have escaped) but Hunca Munca became a pet and a model; she developed an affectionate personality and displayed good housekeeping skills.
