Foreshadowing

"A being which had the shape of a man, but apparently of gigantic stature, sat in the sledge, and guided the dogs."

The beginning of Frankenstein starts out with four letters written by Robert Walton to a Mrs. Saville. In this letter, Robert is describing a strange event that he witnessed one morning. He describes a large figure commanding a sled of dogs racing across the ice. As the reader, we can foreshadow that this is the creature that will appear later on in the novel. Soon after we see this, we learn that this is indeed the creature created by Victor Frankenstein. Frankenstein proceeds to tell his story to Robert after this. He warns Robert of making the same mistakes he did. Victor is on the move chasing his creature down for some unknown reason.
