“ The past had already been dealt with, to one end or another, it was certain, fixed, the horror of it was already over.For the living at least. They grieved, yes, but they were not trapped in the terror of the moment.Not so for my poor, elegant wraiths. They were like the old-fashioned zoetropes you find at the seaside: a tiny slice of a world in a box, brief yet somehow also eternal. ”
