Sheppard is certainly there for us to identify with, to some degree. That said, the sidekick and the audience are not the same thing. But both were, like Poe’s purloined letter on its filigree card-rack, hidden in plain sight the whole time, even if our own ‘little grey cells’ do not have the wit to detect the deception. Up until the reveal, the murderer and the act of murder were not to be found within the pages, as such. The reader has in a sense been used as an unwitting ‘vessel’, concealing Sheppard’s true actions within the act of reading itself.
