It's Christmas Eve, and you are all invited to King's College, Cambridge for a special Christmas revival of the legendary Chit-Chat Club. Mr Jim Moon is in the armchair by the fire and presenting a humorous seasonal haunting from Mr John Kendrick Bangs - The Water Ghost of Harrowby Hall, some festive verse from Sir Walter Scott and Walter de la Mare, and talking about the ancient traditions of Yuletide. But of course, the highlight of this evening's entertainment is a reading of a ghost story from MR James, The Tractate Middoth.
