What clues at the start of the story foreshadow danger for Rainsford?
In the short story "The Most Dangerous Game," there is some foreshadowing of the trouble toward which Rainsford is headed. We get some foreshadowing from the title itself. We can see from the title that something "dangerous" is going to happen. As the story opens the mood of the setting helps set the tone of the story too.
At the very beginning of the story Rainsford is onboard a ship and has a converstation that gives clues. The following quote is taken from the story by Richard Connell
"OFF THERE to the right--somewhere--is a large island," said Whitney." It's rather a mystery--"
"What island is it?" Rainsford asked.
"The old charts call it `Ship-Trap Island,"' Whitney replied." A suggestive name, isn't it? Sailors have a curious dread of the place. I don't know why. Some superstition--" (Book of Short Stories page 293)
Rainsford hears a shot far off in the distance and when he falls overboard, as he is swimming to the island, he hears the cry of an "animal" that he cannot place. These are all clues and I would have been swimming in the opposite direction.
