Everything necessary to understand my grandfather lies between two stories: the story of the tiger’s wife, and the story of the deathless man. These stories run like secret rivers through all the other stories of his life – of my grandfather’s days in the army; his great love for my grandmother; the years he spent as a surgeon and a tyrant of the University. One, which I learned after his death, is the story of how my grandfather became a man; the other, which he told to me, is of how he became a child again.
