And suddenly, what I had imagined was control now seemed mere passivity, what appeared to be harmony was merely a façade. I felt as if I were standing with my back braced against the door of an overstuffed cupboard, struggling to keep the avalanche of clutter inside from sweeping out and overwhelming me. Coming to this house had opened that door, and memories had begun to trickle out: Mah the cook, Micah the gardener. My mother's fingers brushing the door frame, her hand cupping the back of my head.

How many childhood memories does the average person retain? I suspect not many, and those either a generalised composite of experiences or striking events that lodge in the mind like boulders in a stream. And if the average person were to be told that those memories were unreliable, that the utterly familiar home never existed, that the vividly remembered fall from the tree never took place outside of dreams, what then?

That person would begin to mistrust his or her mind.

And that person would be right to do so.

Instead of going to the stairs, I turned the other way and found the library, tugging back one of the sheets to uncover a leather chair. I sat down, dimly aware of creaking floorboards overhead, more immediately interested in the ghosts this room might have.

It was a man's room. So I sat, waiting for my father.

I had been lucky in my parents, blessed for fourteen years to live in the vicinity of two lively, intelligent individuals who loved me, and each other, unreservedly. My self-imposed amnesia, if that is what it was, no doubt had its roots, as Holmes had said, with the double trauma of the accident that took my family's life.

My father had been driving a difficult piece of road in the autumn of 1914, a last family week-end at the lake-house before he enlisted and the war engulfed our lives. He had been distracted, and the motorcar had swerved, hesitated, and then plunged down the cliff into the sea. With the swerve, I had been thrown free; father, mother, and brother had sailed off the world and into the resulting flames.

I spent the rest of the autumn in hospital, and still bore the scars and twinges from my injuries. Worse than the scars, however, was the guilt that started up as soon as consciousness returned—not just the grinding offence of having survived when they had not, but the burning agony of knowing that I, myself, had been the cause of the accident. That I had distracted my father, by starting a loud and petty argument with my younger brother. That I had killed them, and lived to bear the guilt.
