Cryptogram from Frankenstein; or, the modern prometheus, chapter 9

My father observed with pain the alteration perceptible in my disposition and habits and endeavoured by arguments deduced from the feelings of his serene conscience and guiltless life to inspire me with fortitude and awaken in me the courage to dispel the dark cloud which brooded over me. "Do you think, Victor," said he, "that I do not suffer also?

But I was restrained, when I thought of the heroic and suffering Elizabeth, whom I tenderly loved, and whose existence was bound up in mine. I thought also of my father and surviving brother; should I by my base desertion leave them exposed and unprotected to the malice of the fiend whom I had let loose among them?
