When father is taken away unexpectedly, Roberta, Peter, Phyllis and their mother have to leave their wonderful life in London to go and live in a tiny cottage in the country. The children in the nearby railway station, 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.
I would reccommemd this book to 10 year olds and over. The book is quite older so younger children may find it slightly unentertaining. I really enjoyed this book as I always wanted to know what was going to happen next.
