"With the superstition common to his brotherhood, he fancied himself given over to a fiend, to be tortured with frightful dreams, and desperate, the sting of remorse, and despair of pardon; as a foretaste of what awaits him beyond the grave. But it was the constant shadow of my presence!—the closest propinquity of the man whom he had most vilely wronged!--and who had grown to exist only by this perpetual poison of the direst revenge! Yea, indeed!—he did not err!—there was a fiend at his elbow! A mortal man, with once a human heart, has become a fiend for his especial torment!" (Chapter 14)
