This clue was for us old timers who knew Beryl Reid from her days in the early 1950s when she was Monica in the radio programme Educating Archie. Of course she went on to many other things and had a successful career in TV and films later on. She died in 1996.
Archie was a ventriloquist's dummy...............on radio!! His voice was provided by Peter Brough. When he progressed to TV it was apparent he was a rubbish ventriloquist so he went back to radio.
