He had charm, of course; he still has. Charm is often despised but I can never see why. No one has it who isn’t capable of genuinely liking others, at least at the actual moment of meeting and speaking. Charm is always genuine; it may be superficial but it isn’t false. When Xan is with another person he gives the impression of intimacy, interest, of not wanting any other company. He could hear of that person’s death the next day with equanimity, could probably even kill him without scruple. Now I can watch him on television as he gives his quarterly report to the nation and see the same charm.

Both our mothers are now dead. They were nursed to the end at Woolcombe, which is now a nursing home for the nominees of the Council. Xan’s father was killed in a car crash in France the year after Xan became Warden of England. There was some mystery about it; no details were ever released. I wondered about the crash at the time, still do wonder, which tells me a lot about my relationship with Xan. With part of my mind I still believe him capable of anything, half needing to believe him ruthless, invincible, beyond the bounds of ordinary behaviour, as he had seemed to be when we were boys.

The sisters’ lives had taken very different paths. My aunt, by a fortunate combination of beauty, ambition and good luck, had married a middle-aged baronet, my mother a middle-grade civil servant. Xan was born at Woolcombe, one of the most beautiful manor houses in Dorset. I was born in Kingston, Surrey, in the maternity wing of the local hospital, and taken home to a semi-detached Victorian house in a long, dull road of identical houses leading up to Richmond Park. I was brought up in an atmosphere redolent of resentment. I remember my mother packing for my summer visit to Woolcombe, anxiously sorting out clean shirts, holding up my best jacket, shaking it and scrutinizing it with what seemed a personal animosity, as if simultaneously resenting what it had cost and the fact that, since it had been bought too large, to allow for growth, and was now too small for comfort, there had been no intervening period in which it had actually fitted.
