Once Sangarre, being implicated in a very serious affair, had been saved by the Russian officer. She never forgot what she owed him, and had devoted herself to his service body and soul.

When Ivan Ogareff entered on the path of treason, he saw at once how he might turn this woman to account. Whatever order he might give her, Sangarre would execute it. An inexplicable instinct, more powerful still than that of gratitude, had urged her to make herself the slave of the traitor to whom she had been attached since the very beginning of his exile in Siberia.

Confidante and accomplice, Sangarre, without country, without family, had been delighted to put her vagabond life to the service of the invaders thrown by Ogareff on Siberia. To the wonderful cunning natural to her race she added a wild energy, which knew neither forgiveness nor pity. She was a savage worthy to share the wigwam of an Apache or the hut of an Andaman.

Since her arrival at Omsk, where she had rejoined him with her Tsiganes, Sangarre had not again left Ogareff. The circumstance that Michael and Marfa Strogoff had met was known to her. She knew and shared Ogareff's fears concerning the journey of a courier of the Czar. Having Marfa Strogoff in her power, she would have been the woman to torture her with all the refinement of a RedSkin in order to wrest her secret from her. But the hour had not yet come in which Ogareff wished the old Siberian to speak. Sangarre had to wait, and she waited, without losing sight of her whom she was watching, observing her slightest gestures, her slightest words, endeavoring to catch the word "son" escaping from her lips, but as yet always baffled by Marfa's taciturnity.
