Meet Tommy Twitchnose, who lives with his wife and two children in a cosy little house under the floorboards in a converted barnhouse. Tommy and his family have a happy life, foraging for scraps of food and doing up their home with bits and pieces dropped by the humans who live above them. But then, one day, their peaceful life is rudely interrupted. A large family of town mice suddenly appears on their doorstep, led by a daring and determined mouse called Danny, who announces that they're moving in... The adventures that follow will charm, amuse and amaze all who read them - children and grown-ups alike!
