the most dangerous game

The story goes down somewhere in the Caribbean Sea. Rainsford eventually lands on the ominous "ship-trap Island". The mood of the story is filled with danger and mystery in the thick Caribbean night. Words describing the island include "evil" and "danger". 

"Maybe. But sometimes I think sailors have an extra sense that tells them when they are in danger. Sometimes I think evil is a tangible thing--with wave lengths, just as sound and light have. An evil place can, so to speak, broadcast vibrations of evil. Anyhow, I'm glad we're getting out of this zone. Well, I think I'll turn in now, Rainsford."
