Conclusion
MICHAEL STROGOFF was not, had never been, blind. A purely human phenomenon, at the same time moral and physical, had neutralized the action of the incandescent blade which Feofar's executioner had passed before his eyes.

It may be remembered, that at the moment of the execution, Marfa Strogoff was present, stretching out her hands towards her son. Michael gazed at her as a son would gaze at his mother, when it is for the last time. The tears, which his pride in vain endeavored to subdue, welling up from his heart, gathered under his eyelids, and volatiliz-ing on the cornea, had saved his sight. The vapor formed by his tears interposing between the glowing saber and his eyeballs, had been sufficient to annihilate the action of the heat. A similar effect is produced, when a workman smelter, after dipping his hand in vapor, can with impunity hold it over a stream of melted iron.

Michael had immediately understood the danger in which he would be placed should he make known his secret to anyone. He at once saw, on the other hand, that he might make use of his supposed blindness for the accomplishment of his designs. Because it was believed that he was blind, he would be allowed to go free. He must therefore be blind, blind to all, even to Nadia, blind everywhere, and not a gesture at any moment must let the truth be suspected. His resolution was taken. He must risk his life even to afford to all he might meet the proof of his want of sight. We know how perfectly he acted the part he had determined on.
