The caustic soda was working. It was dissolving the clog—a monstrous tangle of bacon grease, potato peels, and a clump of her own long, gray hair. But the reaction was more violent than she’d anticipated. The pipe, old cast iron already pitted with rust, was not just being cleared. It was being eaten.
