Plot hole: Barney Kale decides to reopen a case he couldn't solve. Based on the outcome it makes no logic whatsoever. He is the murderer. Why would he bring attention to it put himself in danger? (00:46:50)
Suggested correction: He was being blackmailed by Gary Roberts. He "reopened" the case as a ruse to kill Roberts.
Trivia: The song Angela Lansbury sings, "Little Yellow Bird," when she plays musical hall performer Emma, is the same song she sang in the 1945 film The Picture of Dorian Gray, when she played music hall performer Sybil Vane.

Question: Why did the Phantom run out of nowhere after tying up the killer when Grady came into the room with Jessica? Did the Phantom try to avoid being seen by others except Jessica?
Answer: Yes, he didn't want to be a hero. He liked being the Phantom going anywhere and doing what he pleases with people thinking there was a ghost.
