There Are No Monsters on Rancho Buenavista
In Folktales of Mexico, compiled by Américo Paredes (one of the founding fathers of Chicano studies in the U.S.), I read a story about a man who discovered that his wife was a monster. Any night the man was away, the wife stripped away her skin and flew through the air as a skeleton, terrorizing the people of the town and stealing infants to eat.
