There have been veiled if persistent questions raised thus far about Victor's mental
stability. These will slowly increase over the course of the novel, to such an extent,
indeed, that near its end (III:WC:26), Walton has every reason to think he is himself
listening to "the ravings of insanity." Questions of conventional expectations and
of documentary evidence are present on all levels of this novel, in issues ranging
from verisimilitude in writing to justice in society.
