The Inspector asks Walter, the psychic, to write down three words from the Ripper's note, as if intending to compare the psychic's handwriting with the Ripper's to see if they were produced by the same man; yet after the psychic hands the Inspector the note, the Inspector does not do even a momentary visual comparison of the two pieces of writing. So, with no evidence that the two men have the same handwriting, on what grounds does he hold Walter in jail? It seems that the Inspector's reason for holding Walter was that he claimed to have foreseen the cut-off ear of a female victim -- a promise contained in the Ripper's note, which (the Inspector reasoned) only the Ripper could have known about. But if that was sufficient grounds to hold Walter, why bother to ask for a sample of Walter's handwriting? And if it was insufficient grounds, so that confirmation from handwriting was necessary, then why did the Inspector pay no attention to the handwriting sample? Apparently there was a slip-up in communication between screenwriter, actor, and director regarding what the handwriting sample was to establish.
In his opening monologue, host Boris Karloff refers to the principal character in the story as George Durst. In the program, the man's name is Walter Durst.
Walter flashes back to his dream. He says "...the building was all a blur, and then all at once..." however his mouth does not continue to move when he says "and then." The picture then fades to his dream.
