"The ghouls are out on Franklin Street. They wear black shawls and keep single file on the sidewalk. At the corner of Greenpoint Avenue, they turn and laugh. The bottoms of their faces are stained red. One takes the plastic knife from his belt and twirls it in the air in front of him. This is how I know they are not real ghouls, but impostors. Ghouls don't use knives: their touch causes paralysis."
