I am not sure about all the background for this, but instead of the usual pilot episode, "The Veil" went as far as making 10 episodes--yet was not, apparently, picked up by the networks as a series. Many of these original shows are available for free download at archive.org (a site often linked to IMDb). I've seen most of the shows and enjoy them--but this one has an unusual difference. Boris Karloff ONLY appears in this one to introduce and close the show--he does not act in the show itself (which he did in the other nine). I think this is because this particular episode was not really part of the series but was bought from the British production team that made it.
When the show begins, you know that several of the Jack the Ripper murders have already occurred. Walter Durst, a so-called 'clairvoyant' (i.e., a psychic who sees the future) begins receiving visions of the murders and can help the police locate him. At first, the police ignore him. Then, after they realize how much he knows, they arrest him and think HE is the Ripper! However, while he's incarcerated, another grisly murder occurs--and the police decide to use Durst to locate the killer.
This episode CLAIMS it's all true and based on real records of the time. However, my research into Durst as well as the name of the man they CLAIM was the Ripper came up with nothing. Clearly the show is total fiction but they did a nice job of making it seem plausible. All in all, very interesting...but blarney.
