I observed that he wore a large coat and muffler and that he was walking under an umbrella.

Another man, also under an umbrella, fell in with us at the next corner.

As we walked along in silence I heard some person coming at a run down the street quite a distance behind us.

I was listening to this sound when I received a terrific blow on the back of the head.

I fell forward, one side of my face striking heavily upon the pavement.
