Why didn't rainsford escape from his room during the night?

Rainsford didn't escape from his room during the night because he was likely assessing his situation and waiting for the right moment to act. He understood that attempting to escape might be risky, as the island was controlled by the cunning General Zaroff, who was always on the lookout for his prey. Additionally, Rainsford needed to strategize and prepare for the hunt rather than make a hasty decision that could lead to his capture. Ultimately, he chose to confront the danger head-on rather than flee in the dark.
