The Ghost Recording [SFX: Tape recorder playback. Cassette tape rewind] NARRATOR: The balcony voice came from an old show-control sampler. Its file contained Julian arguing that a theatre fire ten years earlier had not begun in faulty wiring. He accused Adrian of using smoke during an illegal audience stunt. MABEL ROOK: One dresser died in that fire. The company called it an accident and reopened in a month. ADRIAN FOX: Julian blamed me whenever attention wandered from him. IRIS KENT: He planned to expose the fire on opening night. NARRATOR: Jon discovered the blackout cable had been cut by a motorized scenery knife triggered from the same cue. The system could perform murder without anyone moving in darkness. [SFX: Electric motor. Knife cut rope] JON BELL: Whoever programmed it understood automation. SANA VALE: Adrian demanded automated transitions so reviewers would call the production seamless. NARRATOR: In Julian's dressing room, Iris found iron filings around the mirror and a costume needle magnetized strongly enough to point at the floor. Julian had discovered the blade in his lining before the show. Why had he worn it? MABEL ROOK: Because he thought it was evidence and wanted the trap to reveal itself publicly. IRIS KENT: He understood the blade. He did not know the magnet would be powerful enough to kill him.
