In the last episode of the festive season, and indeed of the year, Mr Jim Moon takes a look at what makes a good Christmas ghost story. We have a chat about the latest BBC Ghost Story for Christmas, The Dead Room starring Simon Callow and written and directed by Mark Gatiss, which aired this Christmas Eve. And then we hear from the master of the ghost story himself, MR James, with three readings of various essays and articles where he outlined his own rules for writing ghost stories.
