ide?"

"Your ladyship is too kind to me."

"It is impossible to be too kind to you."

Mercy started. The color flowed charmingly over her pale face. "Oh!" she
exclaimed, impulsively. "Say that again!"

"Say it again?" repeated Lady Janet, with a look of surprise.

"Yes! Don't think me presuming; only think me vain. I can't hear you say
too often that you have learned to like me. Is it really a pleasure to
you to have me in the house? Have I always behaved well since I have
been with you?"

(The one excuse for the act of personation--if excuse there could
be--lay in the affirmative answer to those questions. It would be
something, surely, to say of the false Grace that the true Grace could
not have been worthier of her welcome, if the true Grace had been
received at Mablethorpe House!)

Lady Janet was partly touched, partly amused, by the extraordinary
earnestness of the appeal that had been made to her.

"Have you behaved well?" she repeated. "My dear, you talk as if you were
a child!" She laid her hand caressingly on Mercy's arm, and continued,
in a graver tone: "It is hardly too much to say, Grace, that I bless the
day when you first came to me. I do believe I could be hardly fonder of
you if you were my own daughter."

Mercy suddenly turned her head aside, so as to hide her face. Lady
Janet, still touching her arm, felt it tremble. "What is the matter with
you?" she asked, in her abrupt, downright manner.

"I am only very grateful to your ladyship--that is all." The words were
spoken faintly, in broken tones. The face was still averted from Lady
Janet's view. "What have I said to provoke this?" wondered the old lady.
"Is she in the melting mood to-day? If she is, now is the time to say
a word for Horace!" Keeping that excellent object in view, Lady Janet
approached the delicate topic with all needful caution at starting.

"We have got on so well together," she resumed, "that it will not be
easy for either of us to feel reconciled to a change in our lives. At
my age, it will fall hardest on me. What shall I do, Grace, when the day
comes for parting with my adopted daughter?"

Mercy started, and showed her face again. The traces of tears were in
her eyes. "Why should I leave you?" she asked, in a tone of alarm.

"Surely you know!" exclaimed Lady Janet.

"Indeed I don't. Tell me why."

"Ask Horace to tell you."

The last allusion was too plain to be misunderstood. Mercy's head
drooped. She began to t
