Explanation:
Captain Walton gives the frame story in Frankenstein, the fictional epistolary means by which the complete story is designed and written. Walton corresponds with his sister, describing how he found Victor Frankenstein on the Arctic ice, and what effect Frankenstein's story (and later the Monster's story) had on him. Writing it down also presents Walton to study and reflect on Frankenstein's life in detail .
