" It's a curious thing with George. With his glasses off, his eyes looked small and weak - blinky and a bit baffled, like an unintelligent sheep that's taken a wrong turn. But when he put them on again, they went all sharp and steely, more like the eyes of an eagle that eats dumb sheep for breakfast. "

― Jonathan Stroud , The Screaming Staircase (Lockwood & Co., #1)
