How does Rainsford manage to wound Zaroff?
My question is about this passage: "I will not lose my nerve. I will not." He slid down from the tree and struck off again into the woods. His face was set, and forced the machinery of his mind to function.
Rainsford manages to hurt Zaroff just a little bit by setting a trap for him.
Specifically, Rainsford uses a big tree that is leaning on a little one. We are not told exactly how he manages it with only a knife as a tool, but he is able to make it so that the big tree will fall when Zaroff touches a trigger (a protruding branch). Zaroff touches the trigger and the tree falls. But Zaroff is quick enough and is paying good attention so the tree only hits his shoulder a little.
