The Circles
There were three circular outlines in the wall, behind the paint — as if they had been painted over. Two of the circles were relatively small, but the third was much larger. Cyrex686 was intrigued to see that it may even be wide enough for a person to fit inside. He knew that there had been something there behind the wall. His first thought was that perhaps they were pipes that had been filled in. But he could never have guessed their true purpose just by looking.
