However varied the reasons might be for the phenomenon, Frankenstein continually reverts
to the importance of documentary evidence to substantiate the truth of its events
or assertions. This will be seen as crucial in the case of the Creature's existence
and experiences (see II:6:7), of Victor's rectitude as a narrator (see III:WC:2),
even of Walton's day-to-day account of his voyage (likewise contained in letters "in
[his] own handwriting"). The pattern suggests that what is at stake here is the underlying
truth of all fictions.
