"Was he tall?" she asked.

"Very tall."

"And very handsome? Come, speak, my daughter."

"He was very handsome," replied Nadia, blushing.

"It was my son! I tell you it was my son!" exclaimed the old woman, embracing Nadia.

"Your son!" said Nadia amazed, "your son!"

"Come," said Marfa; "let us get to the bottom of this, my child. Your companion, your friend, your protector had a mother. Did he never speak to you of his mother?"

"Of his mother?" said Nadia. "He spoke to me of his mother as I spoke to him of my father--often, always. He adored her."

"Nadia, Nadia, you have just told me about my own son," said the old woman.

And she added impetuously, "Was he not going to see this mother, whom you say he loved, in Omsk?"

"No," answered Nadia, "no, he was not."

"Not!" cried Marfa. "You dare to tell me not!"

"I say so: but it remains to me to tell you that from motives which outweighed everything else, motives which I do not know, I understand that Nicholas Korpanoff had to traverse the country completely in secret. To him it was a question of life and death, and still more, a question of duty and honor."

"Duty, indeed, imperious duty," said the old Siberian, "of those who sacrifice everything, even the joy of giving a kiss, perhaps the last, to his old mother. All that you do not know, Nadia--all that I did not know myself--I now know. You have made me understand everything. But the light which you have thrown on the mysteries of my heart, I cannot return on yours. Since my son has not told you his secret, I must keep it. Forgive me, Nadia; I can never repay what you have done for me."

"Mother, I ask you nothing," replied Nadia.

All was thus explained to the old Siberian, all, even the conduct of her son with regard to herself in the inn at Omsk. There was no doubt that the young girl's companion was Michael Strogoff, and that a secret mission in the invaded country obliged him to conceal his quality of the Czar's courier.

"Ah, my brave boy!" thought Marfa. "No, I will not betray you, and tortures shall not wrest from me the avowal that it was you whom I saw at Omsk."

Marfa could with a word have paid Nadia for all her devotion to her. She could have told her that her companion, Nicholas Korpanoff, or rather Michael Strogoff, had not perished in the waters of the Irtych, since it was some days after that incident that she had met him, that she had spoken to him.

But she restrained herself, she was silent, and contented herself with saying, "Hope, my child! Misfortune will not overwhelm you. You will see your father again; I feel it; and perhaps he who gave you the name of sister is not dead. God cannot have allowed your brave companion to perish. Hope, my child, hope! Do as I do. The mourning which I wear is not yet for my son."

CHAPTER III BLOW FOR BLOW

SUCH were now the relative situations of Marfa Strogoff and Nadia. All was understood by the old Siberian, and though the young girl was ignorant that her much-regretted companion still lived, she at least knew his relationship to her whom she had made her mother; and she thanked God for having given her the joy of taking the place of the son whom the prisoner had lost.

But what neither of them could know was that Michael, having been captured at Kolyvan, was in the same convoy and was on his way to Tomsk with them.

The prisoners brought by Ivan Ogareff had been added to those already kept by the Emir in the Tartar camp. These unfortunate people, consisting of Russians, Siberians, soldiers and civilians, numbered some thousands, and formed a column which extended over several versts. Some among them being considered dangerous were handcuffed and fastened to a long chain. There were, too, women and children, many of the latter suspended to the pommels of the saddles, while the former were dragged mercilessly along the road on foot, or driven forward as if they were animals. The horsemen compelled them to maintain a certain order, and there were no laggards with the exception of those who fell never to rise again.
