There is only one I remember… and I can’t remember the name of it. There’s a little kid traveling with his parents on a train. I don’t remember the drama the parents were having, but he kept interrupting. Finally the dad says that if he can not say a word until [midnight?], he’ll give him a shiny silver dollar.
The train stalls in the snow and is stuck. There’s a report of an escaped lunatic. The kid sees someone outside of the train and wants to tell someone… but the lure of the shiny silver dollar keeps him quiet.
At the end…
… we find out that the lunatic is harmless, and the authorities just want to find him and bring him back to safety. As the tracks are cleared and the train begins to move, the little boy sees the man’s hands sliding down the rear window of the carriage.
