Frankenstein is written in the form of a frame story that starts with Captain Robert Walton writing letters to his sister. It takes place at an unspecified time in the 18th century, as the letters' dates are given as ”17-”. In the story following the letters by Walton, the readers find that Victor Frankenstein creates a monster that brings tragedy to his life.
