As I read Walton’s letters, which frame Mary Shelley’s novel, I wonder about who he is? He seems to have conflicting characteristics.  Although we all have multiple facets, I can’t yet make sense of Walton’s various personality traits.  Is he confused, or am I?  Has Shelley created a credible character?  How deeply does she need to develop someone whose main role is to establish the novel’s verisimilitude?  In other words, am I applying inappropriate standards to the effectiveness of his character?
