Harry Houdini: Magic Among The Spirits first ran on KRCB in 2014. Because it deals so specifically with local history, I don't expect it will air on PBS nationally. It is available on DVD under the original title, The Annual Harry Houdini Séances, although it's tricky to find. (Joe Notaro recently reviewed the DVD at Harry Houdini Circumstantial Evidence.)
