When Father goes away with two strangers one evening, the lives of Roberta, Peter and Phyllis are shattered. They and their mother have to move from London home to a simple country cottage, where Mother writes books to make ends meet. However, they soon come to love the railway that runs near their cottage. When they save a train from disaster, an Old Gentleman they often waved to from the platform helps to solve the mystery of their father's disappearance. These Collectors Edition compact hardbacks are ‘cloth-bound’ with matching coloured end papers and embossed gold lettering.
