The yellow butterfly
"It was then that she realized that the yellow butterflies preceded of the appearances of Mauricio Babilonia [...]
One morning, while she was pruning the roses, Fernanda let out a cry of fight and had Meme taken away from the spot where she was, which was the same place in the garden where Remedios the beauty had gone up to haven.
She had thought for an instant that the miracle was going to be repeated with her daughter, because she had been bothered by a sudden flapping of wings.
It was the butterflies" (14.23)
