"Rainsford held his breath. The general's eyes had left the ground and were traveling inch by inch up the tree. Rainsford froze there, every muscle tensed for a spring. But the sharp eyes of the hunter stopped before they reached the limb where Rainsford lay; a smile spread over his brown face. Very deliberately he blew a smoke ring into the air; then he turned his back on the tree and walked carelessly away, back along the trail he had come."
This quote shows the conflict between Rainsford and Zaroff because Zaroff is hunting Rainsford and while also toying with him. This shows the man vs. man conflict by showing Zaroff walking up to the tree ready to kill Rainsford but choosing to wait for another time.
