Olivia made no reply to this speech. She had seated herself in her chair by the window; she looked straight before her into the flagged quadrangle, with her hands lying idle in her lap. It seemed as if she were actually unconscious of her visitor's presence, or as if, in her scornful indifference, she did not even care to affect any interest in that visitor's conversation.

Lavinia Weston returned again to the attack.

"Pray, Mrs. Marchmont, do not think me intrusive or impertinent," she said pleadingly, "if I ask you to favour me with the true particulars of this sad event. I am sure you will be good enough to remember that my brother Paul, my sister, and myself are Mary Marchmont's nearest relatives on her father's side, and that we have therefore some right to feel interested in her?"

By this very polite speech Lavinia Weston plainly reminded the widow of the insignificance of her own position at Marchmont Towers. In her ordinary frame of mind Olivia would have resented the ladylike slight, but to–day she neither heard nor heeded it; she was brooding with a stupid, unreasonable persistency over the words "mental deficiency," "weak intellect." She only roused herself by a great effort to answer Mrs. Weston's question, when that lady had repeated it in very plain words.

"I can tell you nothing about Miss Marchmont's flight," she said, coldly, "except that she chose to run away from her home. I found reason to object to her conduct upon the night of the ball; and the next morning she left the house, assigning no reason––to me, at any rate––for her absurd and improper behaviour."

"She assigned no reason to you, my dear Mrs. Marchmont; but she assigned a reason to somebody, I infer, from what you say?"

"Yes; she wrote a letter to my cousin, Captain Arundel."

"Telling him the reason of her departure?"

"I don't know––I forget. The letter told nothing clearly; it was wild and incoherent."

Mrs. Weston sighed,––a long–drawn, desponding sigh.
