I have the shape of a dead man on the wall of my cell. It was left behind by the last occupant. He stood against the wall and traced around himself with a pencil, then shaded it in. It looks like a very faint shadow, and it’s barely noticeable until you see it. It took me nearly a week to notice it for the first time, but once you see it you can’t un-see it.…Perhaps it’s just superstition, but I can’t help feeling that erasing it would be like erasing the fact that he ever existed. That may not be such a bad thing, all things considered, but I won’t be the one to do it.
