None of us is immortal. However, I hope he has made the great escape to a private room with yummy food and nice whisky and whatever. Must be better than mooching around Sandringham with all the crap that has been going on with his son and the forced jollity and NOISE.
I wish him well, and hope it is nothing serious, but that family is quite practical and a little cold if you ask me, so there will no deathbed gatherings I don't think. Probably what he wants anyway, stiff upper lip Officer Class.
He will emerge in Mid January or something and go on a carriage ride with Lady Sarah. Sorted.
