When Father is taken away unexpectedly; they have to leave their comfortable life in London to go and live in a small cottage in the country. The children seek solace in the nearby railway station; and make friends with Perks the Porter and the Station Master himself. Each day; Roberta; Peter and Phyllis run down the field to the railway track and wave at the passing London train; sending their love to Father. Little do they know that the kindly old gentleman passenger who waves back holds the key to their father's disappearance. ----------- One of the best-loved classics of all time published in hardback with a wonderful introduction by Jacqueline Wilson.
