Horseplay. I am playing hide and seek in a carpet-lined compound where all rooms are connected to other rooms by way of steep ladders. In a moment of carelessness I knock two playmates off their own ladders onto a small landing. One of them can't stop laughing about the fall. The other brushes herself off with a hesitant look. At first it seems that her face has been deeply scarred, with blood welling up from five parallel gashes that run the length of her cheek and jaw. As her look turns to one of disgust, I notice that the darkness under her skin is not blood. It is the surface of a mask fitted beneath her flesh and skin, a smooth red mask wrapped tightly around her skull.
