Elsewhere, the same amount of labor might've made a keg of butter or a week's worth of firewood; here it was spent on raising a block several inches, so that it could be carted into the city and raised by other workers, higher and higher, so that Parisians could have rooms higher than they were wide, and windows taller than the trees they looked out at. Paris was a city of stone, the color of bone, beautiful and hard – you could dash yourself against it and never leave a mark.

Off to the right, as he looked upstream, was the Île de la Cité, crowded and looming with important stuff: the twin, square towers of Notre Dame, and the twin, round towers of the Conciergerie, holding out prospects of salvation and damnation like a mountebank telling him to pick a card, any card. The Palais de Justice was there, too, a white stone monster decorated with eagles, ready to pounce.
