Excellent! They're putting on another christmas ghost story adaptation of one of M.R. James' short stories. This time it's Number 13. I've got a warning to the curious and Oh, whistle and I'll come to you. Did they do any others? The Signal man is also superb but not M.R. James
Right, I didn't know that. I've google'd it and you're correct: 1973, Ghost Story for Chrismas, Lost Hearts. Can't find it on Amazon though, shame I'd like to see that. They should put them all together into a collector's edition. They're all quality British films.
