In the broom cupboard of a small dwelling called Rose Cottage, stands a house fit for a mouse - well, two mice actually. A house made of pebblestone, with gables on the windows and turrets peeking out of the roof. A house with a ballroom, a billiard room, a banqueting room, a butler's room and a drawing room. The house belongs to Mr and Mrs Nutmouse, or Tumtum and Nutmeg as they affectionately call each other.
