The Black Museum was a 52 episode BBC production whose main attributes are its gimmick (stories based on artifacts related to famous crimes worked on by Scotland Yard) and its narrator (American genius Orson Welles). Likely Welles found himself lacking money while working on the movie Othello in Europe and agreed to record The Black Museum series for a little extra cash. That would have been Wellesian.
Beyond the gimmicks, The Black Museum is standard crime fare spiced up by British sensibilities.

A quick bit of trivia about this particular show - Elliot Lewis as Carney plays opposite his lovely wife Cathy Lewis, as the beautiful but proper sister of the dead man. The Lewises often worked in the same show, and the shows were the better for it. Enjoy...
