" Something pressed against the window, nudging the submarine. Its hide was almost as dark as the waters around it, but its scales glistened from the light inside the room. Jacob badly wanted to douse the oil lamp, to hide inside a different darkness, but he had a feeling that any change inside the room, any step, any dimming of a light, any sound, might be like a beacon to the beast outside. "
