My assignment was to write a book report on The Railway Children, Bobbie (the eldest) just had figured out what happened to their father, he was framed for being a spy for some other country and so he was put in jail, but Bobbie knew that their father didn’t do it. So told her mother that she knew and her mother told her not to tell the other children, (Peter the middle kid and Phyllis the youngest) Bobbie (also known as Roberta, but everyone else calls her Bobbie) promises not to tell the others. 

One day the children are going up on the hills to watch some races, and have a picnic. There was this one person that they called the Hound In The Red Jersey, he was this older kid, whose name was Jim. While he was running in the tunnel he tripped over some wire, and hurt his leg, Peter and Phyllis went to go get help, while Bobbie stayed with Jim, once they got help they took him to The Three Chimneys (their house) and their mother helped him to bed. Bobbie went  to get the doctor, the children stayed downstairs while the doctor fixed Jim’s leg. Later the mother called Jim’s grandfather (who so happened to be the old gentleman) so also called Jim’s school teacher, and for reasons I do not understand she also sent them a letter, I’m guessing to let them know he’s ok. 

Later in the story Bobbie had sent a letter to the old gentlemen asking him if he knew anything about their father. At the end of the story the father returns, now that they had caught the actual person who had committed a crime.
