"I don't know," said Pat. "I've forgotten most of my Poe."
"Remember that story of his—'The Black Cat'?"
"Dimly. The man murdered his wife."
"Yes. That isn't the part I mean. I mean the cat itself—the second cat. You know a cat, used rightly, can be a symbol of horror."
"Indeed yes!" The girl shuddered. "I don't like the treacherous beasts!"
"And this cat of Poe's," continued Nick, warming to his subject. "Just think of it—in the first place, it's black; element of horror. Then, it's gigantic, unnaturally, abnormally large. And then it's not all black—that would be inartistically perfect—but has a formless white mark on its breast, a mark that little by little assumes a fantastic form—do you remember what?"
"No."
"The form of a gallows!"
"Oh!" said the girl. "Ugh!"
"And then—climax of genius—the eyes! Blind in one eye, the other a baleful yellow orb! Do you feel it? A black cat, an enormous black cat marked with a gallows, and lacking one eye, to make the other even more terrible! Literary tricks, of course, but they work, and that's genius! Isn't it?"
