at your door----"

"When?"

"At a quarter to eight."

"Good evening," returned Montriveau, and he hurried home to ask the
porter whether he had seen a lady standing on the doorstep that evening.

"Yes, my Lord Marquis, a handsome woman, who seemed very much put out.
She was crying like a Magdalen, but she never made a sound, and stood
as upright as a post. Then at last she went, and my wife and I that were
watching her while she could not see us, heard her say, 'Oh, God!' so
that it went to our hearts, asking your pardon, to hear her say it."

Montriveau, in spite of all his firmness, turned pale at those few
words. He wrote a few lines to Ronquerolles, sent off the message at
once, and went up to his rooms. Ronquerolles came just about midnight.

Armand gave him the Duchess's letter to read.

"Well?" asked Ronquerolles.

"She was here at my door at eight o'clock; at a quarter-past eight she
had gone. I have lost her, and I love her. Oh! if my life were my own, I

tomorrow we will ride six.--Confound it! Mme de Langeais is no ordinary

The police will put us on her track during the day. She must have a

she is on the road or hidden in Paris. There is the semaphore. We can
stop her. You shall be happy. But, my dear fellow, you have made a
blunder, of which men of your energy are very often guilty. They judge
others by themselves, and do not know the point when human nature gives
way if you strain the cords too tightly. Why did you not say a word
to me sooner? I would have told you to be punctual. Good-bye till
tomorrow," he added, as Montriveau said nothing. "Sleep if you can," he
added, with a grasp of the hand.

But the greatest resources which society has ever placed at the disposal
of statesmen, kings, ministers, bankers, or any human power, in fact,
were all exhausted in vain. Neither Montriveau nor his friends could
find any trace of the Duchess. It was clear that she had entered a
convent. Montriveau determined to search, or to institute a search, for
her through every convent in the world. He must have her, even at the
cost of all the lives in a town. And in justice to this extraordinary
man, it must b
