" I shuddered at the idea of this incarnate fiend, whose soul is black with shocking crimes, mingling free and unobserved amongst the harmless crowds, meditating perhaps a new and more fearful cycle of infamies. I tell you, sir, that an awful being stalks through the streets, a being before whom the sunlight itself should blacken, and the summer air grow chill and dank. "
