“In the old days, when this story took place, time used to run by clockworks. Real clockwork, I mean, springs and cogwheels and gears and pendulums and so on. When you took it apart you could se how it worked, and how to put it together again. Nowadays time runs by electricity and vibrating crystals of quarts and goodness know what else.”
“And then at last she loosened the right screw! Whizz! Bang! the spring flew out with a whirr and hit the low ceiling. Screws and cog wheels flew in every direction. It was like an explosion.”
