We were friends for more than thirty years, which is a long time but, now that he is gone, seems not nearly long enough. I was rather nervous when I first met him, one night in London in 1977, along with his great friend Martin Amis. I had read his journalism and was already in awe of his brilliance and wit and couldn’t think what on earth I could bring to his table. I don’t know if he sensed the diffidence on my part—no, of course he did; he never missed anything—but he set me instantly at ease, and so began one of the great friendships and benisons of my life. It occurs to me that “benison” is a word I first learned from Christopher, along with so much else.
