The Stranger on the Ice — Frankenstein

Walton's fourth letter marks the novel's major turning point. His ship is trapped in ice near the North Pole in late August. The crew spots a gigantic figure crossing the ice on a dogsled, then hours later they discover a European man, nearly frozen, on a separate sledge. Walton's men rescue him and nurse him back aboard.

The stranger is Victor Frankenstein, and Walton immediately recognizes him as the intellectual companion he's been craving. Victor is educated, eloquent, and sensitive, but also broken, grieving, and pursuing something he calls a demon across the ice. When Walton shares his ambitious dreams of discovery, Victor reacts with horror, begging him to listen to his tale before it's too late.

Walton is so thrilled to have found a kindred spirit that he barely hears the warning. He has finally found someone who understands his passion, but that person is a living cautionary tale. The frame narrative shifts here: Walton will soon record Victor's story. Shelley sets up the central parallel between two men destroyed by ambition, one at the start of his quest, one at the end. The mysterious giant on the ice hints that Victor's creation is still out there, still driving the chase.
