"The general was playing with him! The general was saving him for another day's sport. The Cossack was the cat; he was the mouse. Then it was that Rainsford knew the full meaning of terror."
"Rainsford, called the general. If you are within the sound of my voice, which I suppose you are, I am to congratulate you."
"You've done well, Rainsford, the voice of the general called. Your Burmese tiger pit has claimed one of my best dogs. Again you score. I think, Mr. Rainsford, I'll see what you can do against my whole pack."
Rainsford has never dealt with being hunted before, but the person that was hunting him was way beyond his thinking level. For once Rainsford was scared he would die.
Rainsford has injured one of if not the best hunter in the world, and he was congratulating him for it. Normally you would expect him to be mad but not in this scenario.
Rainsford would feel great about himself since the trap he made has killed one of the general's best dogs.
Rainsford ends up taking this chance and it is what leads up to the end where Rainsford kills Zaroff because of his surprise.
"For a moment he stood there thinking an idea that held a wild chance."
Rainsford is confident that he can kill Zaroff and that he has won the hunt. Then Rainsford kills Zaroff and sleeps in the bed.
“Rainsford did not smile. I am a beast at bay, he said, hoarse voice.”
