General Zaroff won't let him go without something in return. General Zaroff tells Rainsford that he wants to hunt for him. So the deal is that whoever wins the battle will be sleeping in that bed tonight and whoever loses will be they have to pay the price for the dog being dead.
General Zaroff challenge him to hunt each other. Zaroff said that he would come for him at dusk. Rainsford followed a trail and at dusk climbed up a tree. Zaroff than looked around and started to look up the tree and he stopped right before he seen him and turned around and laughed.
Next, Rainsford jumped out of the tree and went to the quicksand. He made a trap with the quicksand and another trapp with a knife. Then Ivan and one of the dogs came. The dog ran into the quicksand trap. Then Ivan ran into the knife trap and his head came off and just disappeared.

Then he said that the one how wins will get to sleep in this bed tonight and who ever loses will pay for the death of the dog. Rainsford than slept peacefully that night.
