Steve Punt turns super sleuth and goes in search of a most unusual royal relic: Queen Victoria's voice. He embarks on a journey to the dawn of recorded sound as he tracks down a wax cylinder which may contain the voice, the only suspected recording of Victoria in existence. Via sound archives, strong rooms, forensic audiologists, royal voice coaches, the Queen's apartments and Palace letters he pieces together the story of the lost recording of Queen Victoria and tries to get to the bottom of any message she left for her subjects.
