One evening, two gentlemen come to see Father, who leaves with them and does not come back. His three children, Roberta, Peter and Phyllis, leave London with their mother for a little house in the country, near a railway line. Every morning they wave at the passing train, and an old gentleman at the window ends up waving back.
The mystery of the missing father hangs over this tender story full of adventures, in which the children even stop a train by waving red petticoats.
Simply written, with plenty of dialogue, the novel is easy to read in the language you are learning.
