Croft-Cooke, Rupert. Banquo's Chair: A Play in One Act. London: H.F.W. Deane & Sons, 1930.
You may recall the episode of Alfred Hitchcock Presents that dealt—not altogether obliquely—with Banquo's ghost (for which, q.v.).
With the help of an excellent librarian, I was able to track down the source material. It turned out to be a one-act play with the same title. The story is roughly the same, including the same cleverly twisting ending—but the ending works itself out slightly differently in the play.
I'm attaching images (click on them to enlarge them) of the last four pages of the play so that you can see the difference for yourself. And if you happen to direct any amateur dramatic societies, you might consider putting on this play—I think it is quite likely to please an audience!
