“It seemed like a mistake. And mistakes ought to be rectified, only this one couldn't be. Between the way things used to be and the way they were now was a void that couldn't be crossed. I had to find an explanation other than the real one, which was that we were no more immune to misfortune than anybody else, and the idea that kept recurring to me...was that I had inadvertently walked through a door that I shouldn't have gone through and couldn't get back to the place I hadn't meant to leave. Actually, it was other way round: I hadn't gone anywhere and nothing was changed, so far as the roof over our heads was concerned, it was just that she was in the cemetery.”
