This story is about some children who are shattered after the disappearance of their father but the railway line is always there to lift their sad spirits; so are the Old Gentleman and the porter, Perks. Nevertheless, how will they ever find out the reason of their dear father went missing?
I think that this book is a bit old fashioned but it is still very, very, very good; the author is the next (or actually the previous) Agatha Christy!
E Nesbit is the author of this book and many, many others. Some of the titles of her other works include: ‘The Amulet’, ‘The Phoenix and the Carpet’, and ‘The Five Children and It’
