What happened to General Zaroff at the end of the story?

Zaroff was killed by Rainsford.

The general made one of his deepest bows. "I see," he said. "Splendid! One of us is to furnish a repast for the hounds. The other will sleep in this very excellent bed. On guard, Rainsford." . . .

He had never slept in a better bed, Rainsford decided.
