Bringing Wimsey down from his godlike pedestal can only be good for all concerned. I am sure that (once the nervous breakdown at nearly killing Harriet is over with) Bunter will also derive considerable amusement from it.

I think that the chess pieces are currently in an unremarkable cardboard box either in Wimsey's hotel room or Harriet's locked bedroom, and will survive unscathed. Unless Mr Pomfret or his friend bought them, because Wimsey couldn't get there before closing time yesterday...
