O’Kelly interrupted this conference by whispering something in his ear.—“I will attend her instantly.” “Whom?” said Calantha. “Oh no one.” “Ah speak truly: tell me what mean those words—those mysterious looks: you smile: that moon bears witness against you; tell me all.” “I will trust you,” said Glenarvon. “Oh, my Lord, for God’s sake,” said O’Kelly interfering “remember your vows, I humbly entreat.” “Hear me,” said Glenarvon, in an authoritative tone, repulsing him. “What are you all without me? Tremble then at daring to advise, or to offend me. Lady Avondale is mine; we are but one, and she shall know my secret, though I were on the hour betrayed.” “My Lady you are lost,” said the man, “if you do not hasten home; you are watched: I do implore you to return to the castle.” Lord Glenarvon reluctantly permitted her to leave him; he promised to see her on the following morning; and she hastened home. CHAPTER XXX. Unable to rest, Calantha wrote during the whole of the night; and in the morning, she heard that the Duke was in possession of her letter. Lady Margaret entered, and informed her of this. She also stated that the note would soon be returned into her own hands, and that this might convince her that although much might be suspected from its contents, neither herself nor the Duke were of opinion that Lord Avondale should at present be informed of the transaction. While Lady Margaret was yet speaking, the Duke, opening the door, with a severe countenance approached Calantha, and placing the letter to Lord Glenarvon upon the table, assured her, with coldness, that he considered her as her own mistress, and should not interfere. Lady Margaret without a word being uttered on her part, left the room.
