To my mind's eye, my buried memories of Brandham Hall are like effects of chiaroscuro, patches of light and dark: it is only with effort that I see them in terms of colour. There are things I know, though I don't know how I know them, and things that I remember. Certain things are established in my mind as facts, but no picture attaches to them; on the other hand there are pictures unverified by any fact which recur obsessively, like the landscape of a dream.
