And since we've moved to the realm of fantasy, I'm going to imagine myself invited to this tea, where I would doubtless be struck dumb by the brain-power surrounding me, spill tea on myself, be wittily cut in half by the other participants and take the train back to Claridge's to sob myself to sleep:
Oh, Lytton. He was Duncan Grant's main thing. Grant was also involved (concurrently? The dates of their dalliance don't come to mind) with John Maynard Keynes, the economist whose ideas are running our economic policy in Washington these days (as parsed in the third act of this fascinating This American Life Story story).
