‘I have pressed the first lever,’ said O’Brien. ‘You understand the construction of this cage. The mask will fit over your head, leaving no exit. When I press this other lever, the door of the cage will slide up. These starving brutes will shoot out of it like bullets. Have you ever seen a rat leap through the air? They will leap onto your face and bore straight into it. Sometimes they attack the eyes first. Sometimes they burrow through the cheeks and devour the tongue.’
