If his daughter, Nadia Fedor, had left Russia on the date fixed by the last letter he had received from Riga, what had become of her? Was she still trying to cross the invaded provinces, or had she long since been taken prisoner? The only alleviation to Wassili Fedor's anxiety was when he could obtain an opportunity of engaging in battle with the Tartars-- opportunities which came too seldom for his taste. The very evening the pretended courier arrived, Wassili Fedor went to the governor-general's palace and, acquainting Ogareff with the circumstances under which his daughter must have left European Russia, told him all his uneasiness about her. Ogareff did not know Nadia, although he had met her at Ichim on the day she was there with Michael Strogoff; but then, he had not paid more attention to her than to the two reporters, who at the same time were in the post-house; he therefore could give Wassili Fedor no news of his daughter.

"But at what time," asked Ogareff, "must your daughter have left the Russian territory?"

"About the same time that you did," replied Fedor.

"I left Moscow on the 15th of July."

"Nadia must also have quitted Moscow at that time. Her letter told me so expressly."

"She was in Moscow on the 15th of July?"

"Yes, certainly, by that date."

"Then it was impossible for her--But no, I am mistaken-- I was confusing dates. Unfortunately, it is too probable that your daughter must have passed the frontier, and you can only have one hope, that she stopped on learning the news of the Tartar invasion!"

The father's head fell! He knew Nadia, and he knew too well that nothing would have prevented her from setting out. Ivan Ogareff had just committed gratuitously an act of real cruelty. With a word he might have reassured Fedor. Although Nadia had passed the frontier under circumstances with which we are acquainted, Fedor, by comparing the date on which his daughter would have been at Nijni-Novgorod, and the date of the proclamation which forbade anyone to leave it, would no doubt have concluded thus: that Nadia had not been exposed to the dangers of the invasion, and that she was still, in spite of herself, in the European territory of the Empire.

Ogareff obedient to his nature, a man who was never touched by the sufferings of others, might have said that word. He did not say it. Fedor retired with his heart broken. In that interview his last hope was crushed.

During the two following days, the 3rd and 4th of October, the Grand Duke often spoke to the pretended Michael Strogoff, and made him repeat all that he had heard in the Imperial Cabinet of the New Palace. Ogareff, prepared for all these questions, replied without the least hesitation. He intentionally did not conceal that the Czar's government had been utterly surprised by the invasion, that the insurrection had been prepared in the greatest possible secrecy, that the Tartars were already masters of the line of the Obi when the news reached Moscow, and lastly, that none of the necessary preparations were completed in the Russian provinces for sending into Siberia the troops requisite for repulsing the invaders.

Ivan Ogareff, being entirely free in his movements, began to study Irkutsk, the state of its fortifications, their weak points, so as to profit subsequently by his observations, in the event of being prevented from consummating his act of treason. He examined particularly the Bolchaia Gate, the one he wished to deliver up.

Twice in the evening he came upon the glacis of this gate. He walked up and down, without fear of being discovered by the besiegers, whose nearest posts were at least a mile from the ramparts. He fancied that he was recognized by no one, till he caught sight of a shadow gliding along outside the earthworks. Sangarre had come at the risk of her life for the purpose of putting herself in communication with Ivan Ogareff.

For two days the besieged had enjoyed a tranquillity to which the Tartars had not accustomed them since the commencement of the investment. This was by Ogareff's orders.
