‘What are the possibilities of my strength? That is a thought I have never had before. What if some morning as the old woman stood at the head of the staircase she were suddenly to feel a weight thrusting against the back of her legs? What if she were to lunge forward, grasping at the air, striking her thin skull against the edge of a stair? What would become of me if she were found unmoving at the bottom of the stairway?’
