She alone could rescue him," so ran the letter, "and he only could rescue her." He was in such circumstances, the billet farther informed her, that an attempt to bring any witness of their conference, or even to mention to her father, or any other person whatsoever, the letter which requested it, would inevitably prevent its taking place, and ensure the destruction of her sister.

The letter concluded with incoherent but violent protestations, that in obeying this summons she had nothing to fear personally.
The message delivered to her by Butler from the stranger in the Park tallied exactly with the contents of the letter, but assigned a later hour and a different place of meeting.

Apparently the writer of the letter had been compelled to let Butler so far into his confidence, for the sake of announcing this change to Jeanie.

She was more than once on the point of producing the billet, in vindication of herself from her lover's half-hinted suspicions.

But there is something in stooping to justification which the pride of innocence does not at all times willingly submit to; besides that the threats contained in the letter, in case of her betraying the secret, hung heavy on her heart.
