Suspense's "The Cave of Ali Baba," was closely adapted from the short story of the same name by Dorothy L. Sayers. You can find the original text in the book, Dorothy L. Sayers-The Complete Stories (2002), or Lord Peter: The Complete Lord Peter Wimsey Stories (1986).
This episode relates one adventure in the life of Lord Peter Wimsey, the fictional crime-solving character of Sayers' novels and short stories. The time of this particular case, in which Lord Peter comes back from the dead to infiltrate a secret organization, is December, 1927.
As the episode opens, Joseph Rogers is eating kippers and reading the paper on a Saturday afternoon. Suddenly, a noise at the door gets his attention. When he investigates, he finds that an envelope has been left on the hatstand of his hallway. It contains an invitation and a password to a general meeting that evening--one that he must attend...
Mr. Rogers then begins meticulous preparations for his evening out. Why would he need to go to so much trouble?
Stage actor/director/writer/producer Romney Brent starred as Peter Wimsey, and also appearing, was an unusual group of actors that did not normally appear on Suspense. Perhaps they were chosen by Brent for this performance. They are a collection of Broadway stage actors and silent/early film performers: William Malten, Ara Gerald, Cathleen Cordell, Victor Beecroft, Roland Bottomley, J.W. Austin, William Podmoor, and Ian Martin. This episode aired August 19, 1942.
Romney Brent later appeared in a couple of episodes of the Suspense television series, The Cask of Amontillado (1949) and All Hallows Eve (1952). Like Brent, some of the other actors in this episode went on to work in early television:
