"How can you live with all these skeeters?" asked Alvin.

"I breathe them in and cough them out," said Dead Mary.

"How come they call you that?" asked Alvin. "Dead Mary, I mean."

"Marie la Morte? Cause I know when someone is sick before he know himself. And I know how the sickness will end."

"Am I sick?"

"Not yet, no," said the girl.

"What makes you think I can heal your mother?"

"She will die if somebody does not help, and the yellow fever, personne who live here knows how to cure it."

It took Alvin a moment to decide that the French word she said must mean nobody. "I don't know a thing about yellow fever."

"It's a terrible thing," said the girl. "Quick hot fever. Then freezing cold. My mother's eyes turn yellow. She screams with pain in her neck and shoulders and back. And then when she's not screaming, she looks sad."

"Yellow and fevery," said Alvin. "I reckon the name kind of says it all." Alvin knew better than to ask what caused the disease. The two leading theories about the cause of disease were punishment for sin and a curse from somebody you offended. Course, if either one was right, it was out of Alvin's league.

Alvin was a healer, of a kind-that was just natural for a maker, being sort of included in the knack. But what he was good at healing was broken bones and failing organs. A man tore a muscle or chopped his foot, and Alvin could heal him up good. Or if gangrene set in, Alvin could clean it out, make the good flesh get shut of the bad. With gangrene, too, he knew the pus was full of all kinds of little animals, and he knew which ones didn't belong in the body. But he couldn't do like he did with the water and just tell everything alive to break apart-that would kill the person right along with the sickness.

Diseases that made your nose or bowels run were hard to track down, and Alvin never knew whether they were serious or something that would just get better if you left it alone or slept a lot. The stuff that went on inside a living body was just too complicated, and most of the important things was way too small for Alvin to understand what all was going on.
