My Lady, looking out of window at her favourite son, and lost in gloomy depths of thought, had entirely forgotten that she had invited Miss Rose Aynton to bear her company. She did not venture to look upon her questioner's face, though she felt that it was fixed on hers, reading Heaven knew what. How had she dared to think of liberty with this domestic spy under her very roof! What should she answer to this dreadful question? Something this girl must know, or must suspect, or she would never have ventured thus to allude a second time to the man Derrick, after her rebuff in the morning. Above all things, she would follow Mistress Forest's advice, and get Miss Aynton out of Mirk Abbey. She had intended to speak to her respecting what had just occurred at the breakfast-table; that would also offer an opportunity to say something more.

“Yes, Rose, I am going with you to Belcomb. It is a very favourite spot of mine—very. It was about that expedition, partly, that I wished to speak with you. I was about to ask you to be very careful in your conduct towards my sons this day. It is the last time they will be together for weeks, perhaps. Be kind to my poor Richard. Of course, Walter knew nothing of what has passed between you and his brother; but the bow which he drew at a venture sent home a barbed shot.”

“Under these circumstances, dear Rose,” pursued my Lady, “do you not think it would be better—I know how embarrassing it would be to you to propose it, and therefore, although your hostess, I relieve you of the task—do you not think it would, on the whole, be wiser for you to leave us a little sooner than you had intended?”

The humming of the opera tune, and the odour of the Havana, were growing more distinct, and the elastic footfall on the gravel was coming very near.

“If I consulted my own feelings,” returned Miss Aynton, in firm, clear tones, “I should certainly have left Mirk before this, Lady Lisgard.”

“Hush, Miss Aynton, for Heaven's sake!” cried my Lady, “the window is open.”

“But unless Sir Richard himself,” pursued the girl in more subdued accents, “releases me from my promise to remain until after his birthday, I must, with your permission, madam, do so; otherwise, he might possibly imagine that his presence is too great a trial for me, and I should be loath indeed to have my departure so misconstrued.” There was bitterness in the tone with which she spoke, but determination too.

“I am to understand, then,” returned my Lady flushing, “that contrary to my advice and wish”——
