Every action was expressive of her exhaustion.

The glancing at her watch, the critical inspection of the bundle of papers, yet untyped, that lay beside her on the desk; all these various movements were like the gestures of a dumb show.

Was she going to give in?
From the size of the bundle of papers which she had looked at, there was apparently still a great deal of work left for her to do.
The thought passed across his mind that he would give her until he had counted twenty; if she showed no signs of moving by that time, he decided to wait no longer.
One--two--three--four--she stood up from the desk.

He still watched her until he had seen her place the wooden cover over the machine; then he crossed to the other side of the road and began walking up and down the pavement, passing the door of Bonsfield & Co.

About every twenty yards or so, he turned and passed it again.
Five minutes elapsed.
