Here’s a concise summary of from T. S. Eliot’s Old Possum’s Book of Practical Cats (the basis for the musical Cats ). Summary Skimbleshanks is the unofficial but utterly indispensable supervisor of the Night Mail train. He is a cheerful, energetic, and fastidious ginger cat who ensures everything runs smoothly and on time.
From the moment passengers prepare to board, Skimbleshanks is already busy—checking luggage, inspecting the driver’s cab, and making sure the signal lamps are clean. He patrols the train throughout the journey, keeping order, comforting passengers, and even dealing with any potential trouble. His presence is so essential that the train simply cannot leave without him. |
