He had in his hand all this while neither letters nor telegrams, and now that he was close to her--for she was close to the counter-clerk--it brought her heart into her mouth merely to see him look at her neighbour and open his lips.

She was too nervous to bear it.

He asked for a Post- Office Guide, and the young man whipped out a new one; whereupon he said he wished not to purchase, but only to consult one a moment; with which, the copy kept on loan being produced, he once more wandered off.
What was he doing to her?
What did he want of her?
Well, it was just the aggravation of his "See here!" She felt at this moment strangely and portentously afraid of him--had in her ears the hum of a sense that, should it come to that kind of tension, she must fly on the spot to Chalk Farm.

Mixed with her dread and with her reflexion was the idea that, if he wanted her so much as he seemed to show, it might be after all simply to do for him the "anything" she had promised, the "everything" she had thought it so fine to bring out to Mr.Mudge.

He might want her to help him, might have some particular appeal; though indeed his manner didn't denote that--denoted on the contrary an embarrassment, an indecision, something of a desire not so much to be helped as to be treated rather more nicely than she had treated him the other time.
