Part One-Shelf

We all know that one kid that no one knows about. He doesn't talk and sits at the back of the class in that dark corner. And we both know that one hallway that's always empty and creepy and only has two lights working. That looks like no one has stepped foot on in fifty years.
That one mute kid and dark hallway have seemingly no connection. But no one knows what goes on in the mute one's head.
