George's dog, Timmy, discovers an adventure when he notices some suspicious passengers on a train. He is very interested in one of them, but what has he noticed? Can the Famous Five solve this mystery? In addition to the Famous Five novels, Enid Blyton wrote a series of short stories based on these characters. These were published in magazines and gathered in the Famous Five Short Story Collection. For the first time, the full text of the story "Five and a Half-Term Adventure" (1956) appears in a separate volume, illustrated with vivid modern color images by Jamie Littler.
