I the cause
Here, in a sudden reversal, Victor indicts himself, recognizing his
responsibility for the consequences of a scientific experiment over which
he exerted no intellectual or moral control. And yet, since he has
neither evidence to offer nor can even place himself within Switzerland
when the crime was committed, he is effectually without any responsibility
in the eyes of society. Also, of course, he does not truly know that the
Creature was William's murderer and thus has, in any objective sense,
nothing to offer but supposition that would be inadmissible in a judicial
proceeding.
