Every week, the series aired rebroadcasts of episodes of many popular radio shows of the time. Some include rebroadcast of The Whistler, Mr. and Mrs. North, Inner Sanctum Mystery, and The Adventures of Nero Wolfe.
These are two typical intros that a viewer could find when watching the series;
Host: "Two pairs of footsteps echoed down the alley. He stopped. Waited. Waited for Jack the Ripper to Strike! But this is not London in 1888. No, this is Chicago in 1945! Yet, Jack the Ripper is loose again to knife, to butcher his victims... without a trace!"
Host: "Hello... Creeps. This is Peter Lorre opening the doors to the Mystery Playhouse. If you recall, some 50 years ago, London was terrorized by a one man crime wave. A murderer, who was never captured and never seen. And tonight, we follow the investigations of Sir Guy Holless, who firmly believes that Jack the Ripper is still alive. That it is he that is the fiend, that once again slashes and kills! There is an element of the supernatural in this story, that will amaze you. For it seems that the spirit world has given the black heart of Jack the Ripper, the power of everlasting life!"
