Life at the white house on the hill changes after that. A maid（女仆）and a cook come to their house. Mother stops writing her stories and has more time for the children. Then one day Phyllis says, "We never go to see the railway now. "
"It's true," says Bobbie. "And we don't send our love to Father with the 9:15 train. "
The next day they run to the railway line and wave（挥动）their handkerchiefs（手帕）at the 9:15 train. The old gentleman waves back. But that day he waves his newspaper very hard. And all the passengers（乘客）on the train start to wave. They stand at the windows and wave their handkerchiefs, newspapers and hands.
"I think they are trying to tell us something," says Bobbie. She feels that something is going to happen. She has the same strange feeling when she is doing her homework later. At last she decides to walk to the station to talk to Mr. Perks, the worker at the station.
She meets many people on the way. They all smile at her and say "Good morning".
"Everyone is very nice today," she thinks. "And they all get a newspaper. How strange!"
At the station, the station master smiles at her. He tells her that the 11:54 train is a little late that day. When she sees Mr. Perks on the platform（站台），he has a newspaper in his hand， too.
"On a day like today, miss," he says," I must give you a kiss. "
Bobbie's very surprised. Is it a special day? She can't remember.
Suddenly the 11:54 train comes and Mr. Perks must go. When the train stops, three people get off. A farmer, a lady with some boxes and.. .
"Daddy! My daddy!" Bobbie shouts, "I can't believe you're really here. It is a very special day. I'm so happy!"
Father tells Bobbie that the man from his office is the spy（间谍）. He is in prison（监狱）now. "Thanks to Jim's grandfather," he says. " Now everyone knows the truth. They know that I'm not a spy. I'm very, very happy with my family again. "
