"Mr and Mrs Homeowner have a mouse in their house, and they want it gone. Mr Bosh--big chief mouse-catcher, and Mr Bumble--assistant mouse-catcher (wearing shoes that squeak like a mouse) arrive on the scene. They try all the old tricks: setting a trap, bringing in a (big!) cat, inviting an elephant round . . . but the mouse is always one step ahead"--OCLC.
