"Dear Miss Henley, let me help you to pack up."

Iris positively refused.

"No," she said, "I don't agree with Mr. Mountjoy. My father leaves it
to me to name the day when we meet. I hold you, my dear, to our
engagement--I don't leave an affectionate friend as I might leave a
stranger."

Even if Mr. Mountjoy communicated his discoveries to Miss Henley, on
the way home, there would be no danger now of her believing him. Mrs.
Vimpany put her powerful arm round the generous Iris, and, with
infinite grace, thanked her by a kiss.

"Your kindness will make my lonely lot in life harder than ever to
bear," she murmured, "when you are gone."

"But we may hope to meet in London," Iris reminded her; "unless Mr.
Vimpany alters his mind about leaving this place."

"My husband will not do that, dear. He is determined to try his luck,
as he says, in London. In the meantime you will give me your address,
won't you? Perhaps you will even promise to write to me?"

Iris instantly gave her promise, and wrote down her address in London.

Mountjoy made no attempt to interfere: it was needless.

If the maid had not fallen ill on the journey, and if Mrs. Vimpany had
followed Miss Henley to London, there would have been little to fear in
the discovery of her address--and there was little to fear now. The
danger to Iris was not in what might happen while she was living under
her father's roof, but in what might happen if she was detained (by
plans for excursions) in Mr. Vimpany's house, until Lord Harry might
join her there.

Rather than permit this to happen, Hugh (in sheer desperation)
meditated charging Mrs. Vimpany, to her face, with being the Irish
lord's spy, and proving the accusation by challenging her to produce
the registered letter and the diamond pin.

While he was still struggling with his own reluctance to inflict this
degrading exposure on a woman, the talk between the two ladies came to
an end. Mrs. Vimpany returned again to the window. On this occasion,
she looked out into the street--with her handkerchief (was it used as a
signal?) exhibited in her hand. Iris, on her side, advanced to
Mountjoy. Easily moved to anger, her nature was incapable of sullen
perseverance in a state of enmity. To see Hugh still patiently
waiting--still risking the chances of insult--devoted to her, and
forgiving her--was at once a reproach that punished Iris, and a mute
appeal that no true woman's heart could resist.
