Lower and lower drooped her head, brighter shone the shame on her hectic cheek.  An awful blow to Mr. Carlyle it must have been; she was feeling it in all its bitter intensity.  Lord Mount Severn read her repentant looks.

“Isabel,” he said, in a tone which had lost something of its harshness, and it was the first time he had called her by her Christian name, “I see that you are reaping the fruits.  Tell me how it happened.  What demon prompted you to sell yourself to that bad man?”

“He is a bad man!” she exclaimed.  “A base, heartless man!”

“I warned you at the commencement of your married life to avoid him; to shun all association with him; not to admit him to your house.”

“His coming to East Lynne was not my doing,” she whispered.  “Mr. Carlyle invited him.”

“I know he did.  Invited him in his unsuspicious confidence, believing his wife to be his wife, a trustworthy woman of honor,” was the severe remark.

She did not reply; she could not gainsay it; she only sat with her meek face of shame and her eyelids drooping.

“If ever a woman had a good husband, in every sense of the word, you had, in Carlyle; if ever man loved his wife, he loved you. How could you so requite him?”

She rolled, in a confused manner, the corners of her warm shawl over her unconscious fingers.

“I read the note you left for your husband.  He showed it to me; the only one, I believe, to whom he did show it.  It was to him entirely inexplicable, it was so to me.  A notion had been suggested to him, after your departure, that his sister had somewhat marred your peace at East Lynne, and he blamed you much, if it was so, for not giving him your full confidence on the point, that he might set matters on the right footing.  But it was impossible, and there was the evidence in the note besides, that the presence of Miss Carlyle at East Lynne could be any excuse for your disgracing us all and ruining yourself.”

“Do not let us speak of these things,” said Lady Isabel, faintly.  “It cannot redeem the past.”

“But I must speak of them; I came to speak of them,” persisted the earl; “I could not do it as long as that man was here.  When these inexplicable things take place in the career of a woman, it is a father’s duty to look into motives and causes and actions, although the events in themselves may be, as in this case, irreparable.  Your father is gone, but I stand in his place, there is no one else to stand in it.”

Her tears began to fall.  And she let them fall—­in silence.  The earl resumed.

“But for that extraordinary letter, I should have supposed you had been actuated by a mad infatuation for the cur, Levison; its tenor gave the matter a different aspect.  To what did you allude when you asserted that your husband had driven you to it?”

“He knew,” she answered, scarcely above her breath.

“He did not know,” sternly replied the earl.  “A more truthful, honorable man than Carlyle does not exist on the face of the earth.  When he told me then, in his agony of grief, that he was unable to form even a suspicion of your meaning, I could have staked my earldom on his veracity.  I would stake it still.”
