If you wish to save the whole family from ruin, you must take steps to keep her away from Greshamsbury now at once.
Now is the time; now that Frank is to be away.

Where so much, so very much depends on a young man's marrying money, not one day ought to be lost." Instigated in this manner, Lady Arabella resolved to open her mind to the doctor, and to make it intelligible to him that, under present circumstances, Mary's visits at Greshamsbury had better be discontinued.

She would have given much, however, to have escaped this business.

She had in her time tried one or two falls with the doctor, and she was conscious that she had never yet got the better of him: and then she was in a slight degree afraid of Mary herself.
She had a presentiment that it would not be so easy to banish Mary from Greshamsbury: she was not sure that that young lady would not boldly assert her right to her place in the school-room; appeal loudly to the squire, and perhaps, declare her determination of marrying the heir, out before them all.

The squire would be sure to uphold her in that, or in anything else.
And then, too, there would be the greatest difficulty in wording her request to the doctor; and Lady Arabella was sufficiently conscious of her own weakness to know that she was not always very good at words.
