“I don't know why it is that one kind of dark can be so different from another. Real dark is thicker and quieter, it fills up the space between your jacket and your heart. It gets in your eyes. When I have to be out late at night, it's not knives and kicks I'm afraid of, though there are plenty of those behind walls and hedges. I'm afraid of the Dark. You, who walk so cheerfully, whistling your way, stand still for five minutes. Stand still in the Dark in a field or down a track. It's then you know you're there on sufferance. The Dark only lets you take one step at a time. Step and the Dark closes round your back. In front, there is no space for you until you take it. Darkness is absolute. Walking in the Dark is like swimming underwater except you can't come up for air.”
