Coronation Street fans think they have figured out Stephen's sinister motive after spotting a clue that he may never have lived abroad.
Audrey's son Stephen emigrated to Canada in 1960 with his adoptive parents and has been living in Italy after moving there in 2007.
Sarah and Bethany Platt moved in with him for a number of years but returned home in 2014 - and it seems that since then, Stephen has been up to no good.
