It was all dark and still in the car, and nobody came in, but the noise kept up outside, and I knew something had gone wrong with the train.

Perhaps Miss Laura had got hurt.

Something must have happened to her or she would come to me.
I barked and pulled at my chain till my neck was sore, but for a long, long time I was there alone.

The men running about outside must have heard me.

If ever I hear a man in trouble and crying for help I go to him and see what he wants.
After such a long time that it seemed to me it must be the middle of the night, the door at the end of the car opened, and a man looked in.
