"I dare say poor old Lord Dreddlington's notion is, that this will be a fine opportunity for bringing about his favorite scheme of _reuniting the families_--Heaven save the mark!" said Mr. Aubrey, just as the twopenny postman's knock at the door was heard; and within a few moments' time the servant brought up-stairs a letter addressed to Mr. Aubrey. The very first glance at its contents expelled the smile from his countenance, and the color from his cheek: he turned, in fact, so pale, that Mrs. Aubrey and Kate also changed color--and came and stood with beating hearts, and suddenly suspended breath, one on each side of him, looking over the letter while he was reading it. As I intend presently to lay a copy of it before the reader, I shall first state a few circumstances, which will make it appear that this same letter may be compared to a shell thrown into a peaceful little citadel, by a skilful, though distant and unseen engineer--in short, I mean Mr. Gammon. CHAPTER XII. The astute and determined person mentioned at the close of our last chapter, had long been bent upon securing one object--namely, access to Mr. Aubrey's family circle, for reasons which have been already communicated to the reader. That Mr. Aubrey was, at all events, by no means _anxious_ for such a favor, had been long before abundantly manifest to Gammon, and yet not in a way to give him any legitimate, or excusable, grounds of offence.

Her beauty, her grace, her elevated character, (of which he had heard much on all hands,) her accomplishments, her high birth--all were exquisitely appreciated by him, and conspired to constitute a prize, for the gaining of which he deemed no exertion too great, no sacrifice too serious, no enterprise too hazardous. He had, moreover, other most important objects in view, to which a union with Miss Aubrey was in fact essential. She was, again, the only person, the sight of whom had in any measure given vitality to his marble heart, exciting totally new thoughts and desires, such as stimulated him to a fierce and inflexible determination to succeed in his purposes. He was, in short, prepared to make almost any sacrifice, to wait any length of time, to do or suffer anything that man could do or suffer, whether derogatory to his personal honor or not--in order either to secure the affections of Miss Aubrey, or, at all events, her consent to a union with him.
