Imagine you've just managed to catch your train and you realise it's the wrong one. You'd be annoyed, of course, but not scared . . . yet.Imagine you get off the wrong train at the next station hoping to catch a train going back the way you came, but the station is empty. Again, you'd be annoyed, but not scared . . . yet.Imagine someone comes to the station, someone who starts to tell you stories to help you pass the time, but these aren't any old stories . . . Scared yet? You will be.
