For 22 years, Sally Leydon has been searching for her missing mother Marion Barter - and for much of that time, she's felt incredibly alone. But now, following the launch of The Lady Vanishes - a 7NEWS.com.au podcast series dedicated to finding out what happened to Marion - tens of thousands of people around the world are helping to try to crack the case.
UPDATE: The first episode of 'The Lady Vanishes' is now live. You can listen and subscribe via acast, Spotify or Apple Podcasts. It's a case that's baffled NSW police for 22 years: the disappearance, without a trace, of Gold Coast teacher, Marion Barter.
