Julian, Dick, Anne, George and Timmy the dog find excitement and adventure wherever they go in Enid Blyton's most popular series. In book seven, the Famous Five investigate spook trains in the dead of night. The trains seem to vanish into thin air, but where do they go? The Five discover an unusual underground tunnel system and a secret train-service. If they follow the tracks, will they solve the mystery?
