"I promise that," he said. And the interview then terminated, Mrs.
Yeobright returning homeward as she had come.

By far the greatest effect of her simple strategy on that day was, as
often happens, in a quarter quite outside her view when arranging it. In
the first place, her visit sent Wildeve the same evening after dark to
Eustacia's house at Mistover.

At this hour the lonely dwelling was closely blinded and shuttered from
the chill and darkness without. Wildeve's clandestine plan with her was
to take a little gravel in his hand and hold it to the crevice at the
top of the window shutter, which was on the outside, so that it should
fall with a gentle rustle, resembling that of a mouse, between shutter
and glass. This precaution in attracting her attention was to avoid
arousing the suspicions of her grandfather.

The soft words, "I hear; wait for me," in Eustacia's voice from within
told him that she was alone.

He waited in his customary manner by walking round the enclosure and
idling by the pool, for Wildeve was never asked into the house by his
proud though condescending mistress. She showed no sign of coming out in
a hurry. The time wore on, and he began to grow impatient. In the course
of twenty minutes she appeared from round the corner, and advanced as if
merely taking an airing.

"You would not have kept me so long had you known what I come about," he
said with bitterness. "Still, you are worth waiting for."
