Captain Walton introductory narrative

Frankenstein is a frame story written in epistolary form. Set in the 18th century, it documents a fictional correspondence between Captain Robert Walton and his sister, Margaret Walton Saville. Robert Walton is a failed writer who sets out to explore the North Pole in hopes of expanding scientific knowledge. After departing from Archangel, the ship is trapped by pack ice on the journey across the Arctic Ocean. During this time, the crew spots a dog sled driven by a gigantic figure. A few hours later, the ice splits apart, freeing the ship, and the crew rescues a nearly frozen and emaciated man named Victor Frankenstein from a drifting ice floe. Frankenstein has been in pursuit of the gigantic man observed by Walton's crew. Frankenstein starts to recover from his exertion; he sees in Walton the same obsession that has destroyed him and recounts a story of his life's miseries to Walton as a warning. The recounted story serves as the frame for Frankenstein's narrative.
