Paul was not slow in following Mike. He was a good runner, and would have had no difficulty in keeping up with his enemy if the streets had been empty. But to thread his way in and out among the numerous foot passengers that thronged the sidewalks was not so easy.

He glared in anger at Paul, but could not at first obtain breath enough to speak.
