Read the excerpt of chapter 12 in Frankenstein.

“My thoughts now became more active, and I longed to discover the motives and feelings of these lovely creatures; I was inquisitive to know why Felix appeared so miserable and Agatha so sad. I thought (foolish wretch!) that it might be in my power to restore happiness to these deserving people. When I slept or was absent, the forms of the venerable blind father, the gentle Agatha, and the excellent Felix flitted before me. I looked upon them as superior beings who would be the arbiters of my future destiny. I formed in my imagination a thousand pictures of presenting myself to them, and their reception of me. I imagined that they would be disgusted, until, by my gentle demeanour and conciliating words, I should first win their favour and afterwards their love.”
