" Julius Harper found home by chance one day. He was walking along Perdita Street on an errand when he saw the winking sun symbol at the top of a derelict, abandoned building.
The sight awakened a slumbering memory in Papa. His mother told him when he was a very little boy that if he ever lost his way to look for the building with the winking sun. It was a distinctive feature on the facade, a sun with a face and one eye open, the other eye shut. In olden times many people didn't know how to read, so they looked for symbols instead.
"Mam drew a picture of it for me," Papa said. Years later, when he saw that symbol, he realized he was looking at the place where he had lived when he was a little boy. "
