After a short time I saw that for the present it was useless to speak to him.

He was sulky, and so I came away.
Later in the day he sent for me.

Ordinarily I would not have come without special reason, but just at present I am so interested in him that I would gladly make an effort.

Besides, I am glad to have anything to help pass the time.

Harker is out, following up clues, and so are Lord Godalming and Quincey.
